Compare all eSIM plans in Argentina

How we got these numbers: we read 78 public customer reviews that mention Argentina or a place in it, published between November 2024 and July 2026, and counted a report as "worked" when the reviewer said the eSIM connected, even with small hiccups. We treat 20 or more reports as strong evidence, 3 to 19 as limited, and fewer than 3 as too few to judge. A count like 20 of 21 means the eSIM worked well for 20 of the 21 travelers who reported from here; each provider section says what went wrong for the rest. The Vefru test score is a separate number: our own hands-on test of the provider, run outside Argentina, so it says how the provider behaves, not how the network performs here. Local operator prices in the text were checked on 25 Sep 2026; provider ratings, the plan tables and the price-per-GB chart are live and update on their own.

We chose the Best group on traveler reports from Argentina first, price position second and our own hands-on findings third; eSIM4Travel is included on its price and test results, because nobody has reported from Argentina with it yet.

Maya Mobile eSIM in our hands

Go to Maya Mobile website View full review

Maya Mobile is the pick for most trips to Argentina because it has the strongest record by a wide margin: it worked well for 20 of 21 travelers who reported from Argentina (95%), the only provider here with 20 or more reports, which we count as strong evidence. The successes cover the places most trips touch: all 4 reports from Buenos Aires worked, and so did single reports from Bariloche, El Chaltén, Iguazú and Patagonia. That spread matters in a country where the research shows coverage thinning out fast beyond the cities.

The one miss, and the place-level reports that did not work, point away from Buenos Aires: one report from El Calafate and one from northern Argentina said the eSIM did not work. Those are the areas where the research shows that which operator you land on decides whether you have signal, and Maya Mobile did not name an Argentine network on its page when we checked in September 2026. Its page also claims no throttling, which the research marks as disputed, so we go by what we measured instead.

What sets it apart is the product: one global unlimited plan that also covers Argentina, in 3, 7, 14 and 30 day versions, with or without cruise coverage, and nothing else, no country plan and nothing under 3 days. Our comparison tool lists it at 5 GB a day at full speed, then slowed until the daily reset, and in our hands-on test that is roughly what happened: no cap from the start, a slowdown only after about 5 GB in a day, the fairest unlimited rule we tested. The QR code arrives by email and on the thank-you page, the app is optional, and you set the APN "globaldata" and data roaming yourself. Hotspot is included. In our price analysis it is by far the cheapest global unlimited plan, below every provider's median 30-day unlimited price, but poor value for a one or two day trip because it sells nothing small. The help desk was the weak spot in our test: a WhatsApp bot that ignored our message, then a five-step form, then a human after about nine minutes with template replies; the details are in our Maya Mobile review. A full refund is available if no data was used within 30 days. Maya Mobile suits a week or more in Argentina, a trip that crosses into Chile or Brazil, and heavy users.

Holafly eSIM in our hands

Go to Holafly website View full review

Holafly is the choice for travelers who want unlimited data and do not want to think about it, and a clean record backs that up: it worked well for 8 of 8 travelers who reported from Argentina (100%), which is limited evidence because of the small number. The one caveat is speed. In our test, Holafly's speed was capped from the start, before any data was used, the only provider slowed that way. In practice that is enough for maps, messaging, browsing and streaming, and slow for large downloads, uploads, cloud backups and laptop work. The same block of terms caps the hotspot at 1 GB a day and allows no top-ups: when the days run out you buy a new eSIM.

There were no misses to describe. The only place-level report is from Buenos Aires, where it worked, so the record says nothing yet about Patagonia or the northwest. Holafly's page names Telefónica as its Argentine network, as of September 2026, which is the brand trade press reports expect to disappear as the divested Movistar lines move to Tuenti before the end of 2026; that is worth a second look at the network cell close to your trip.

What it sells is simple: unlimited data only, priced by the day, with Argentina versions from 3 to 30 days on its page as of September 2026, data only, with an "Always On" allowance of 1 GB every 30 days after the plan ends if you keep the eSIM. Installation is one tap with no QR code, and 5G came up at once in our test; a deleted eSIM cannot be reinstalled. The help desk was a bot followed by a quick, helpful human. In our price analysis Holafly is the most expensive unlimited offer in about half of all comparisons, so this is a safe pick with two stated drawbacks, the cap and the price; our Holafly review has the speed test. Holafly suits a phone-only trip where setup and certainty matter more than speed.

Global YO eSIM in our hands

Go to Global YO website View full review

Global YO is the pick for price-driven travelers who install at home and will not need the help desk. Its record is clean but thin: it worked well for 5 of 5 travelers who reported from Argentina (100%), limited evidence. Two of those reports came from Buenos Aires and two from Patagonia, shared with Chile, so the small sample at least covers both ends of the country.

There were no misses in Argentina. What counts against it comes from our test and from its record elsewhere: the help desk sent a generic template after ten minutes and took more than half an hour to follow up, and across all countries it worked for fewer travelers than the market average. Global YO did not name an Argentine network on its page when we checked in September 2026; the research confirms only that it runs on 4G LTE.

What it sells here is the widest fixed ladder: Argentina plans from 1 GB for 3 days up to 100 GB for 60 days, Day Plans with a daily high-speed allowance, a Latin America Explorer plan for 17 countries and a Global Explorer plan, but no unlimited plan. In our price analysis it is the second cheapest provider overall and gets cheaper as the package grows, so it is the one to compare for 10 GB and more. The catch is the buying process: purchase is app-only, the QR code is then emailed, you switch mobile data to the eSIM yourself with the APN "globaldata", and a deleted eSIM cannot be reinstalled. The app also stops working at 0 data, so top up before you run dry. Outgoing internet calls are built in (YO SHOUT). Its terms say non-refundable while its FAQ promises a 30-day refund on unused plans, a conflict we describe in our Global YO review. Global YO suits a long trip with a big data plan bought before departure.

Roamless is a US provider built around one global eSIM for 203 destinations, paid with pay-as-you-go credit. It was fast and unthrottled in our test, and travelers report it working in 91% of cases.

Roamless eSIM in our hands

Go to Roamless website View full review

Roamless is the pick for light users and for anyone combining Argentina with other countries, because one eSIM and one pot of credit cover everything. It worked well for 4 of 4 travelers who reported from Argentina (100%), limited evidence, and across all countries it is the third most reliable provider in the reports we read. None of the Argentina reports is tied to a specific place, so the record says nothing about Patagonia or the northwest.

There were no misses in Argentina. The trouble we found was in setup: in our test the preselected "Roamless" APN did not work, and data only flowed after we chose "Proximus Internet" with Wi-Fi off, which the help desk fixed in under half an hour. Google Pay failed at checkout and the Android app link was dead when we tested. Roamless names Movistar as its Argentine network on its page, as of September 2026, with 3G, 4G and 5G listed, so it shares the Tuenti transition caveat with Holafly and Airalo.

What it sells is unusual: pay-as-you-go credit that never expires, sold in buckets from 1 GB to 100 GB for Argentina, plus 30-day Argentina plans from 1 GB to 50 GB, 30-day Latin America and Global plans, and a free 400 MB Argentina trial for new users. Roamless claims no throttling and we saw none in our test; the hotspot is unlimited. In our price analysis it is the second cheapest for 1 GB but one of the dearest from 10 GB up, because the per-GB rate has no volume discount, so it suits light use, not a month of streaming. The app handles internet calls and an optional second number, and at zero balance a trickle of data remained in our test, enough to reach the shop without Wi-Fi; see our Roamless review for the APN fix. Sales are final except for an incompatible or locked phone. Roamless is for the traveler who wants one eSIM for Argentina, Chile and Brazil and will use a few GB in each.

GigSky eSIM in our hands

Go to GigSky website View full review

GigSky is the pick for the far south and for cruise passengers, because its reports come from exactly those places: it worked well for 11 of 12 travelers who reported from Argentina (92%), limited evidence, with single working reports from Ushuaia, Bariloche and Patagonia (shared with Chile). The research also records a review that credits GigSky's network failover in Ushuaia. Together with its cruise and Americas plans, that makes it the one provider here with evidence from the bottom of the map.

The one miss was in Buenos Aires, where 2 of 3 reports worked, not in the south. GigSky's page does not name an Argentine operator, only that the network varies, as of September 2026, which is consistent with the failover the Ushuaia review describes. In our test the speed felt unstable, with a big jump after a restart, though we saw no throttling.

What it sells is the same ladder GigSky offers almost everywhere: Argentina plans of 1 GB for 7 days, 3 GB for 15 days, 5 and 10 GB for 30 days, 20 GB for 90 days and a 1-day unlimited pass that its page says slows after 2.5 GB, plus Latin America, World and Cruise plans that include Argentina. Two things set it apart in practice. The app stays partly online after the data runs out, so you can buy another plan without Wi-Fi, which only Ubigi matched in our test. And the help desk answered at once with a human. The downsides: you must install the app to buy, name your device, set the APN "gigsky" and keep the eSIM off until you travel because it starts on first connection and cannot be paused. In our price analysis GigSky is the most expensive provider overall, driven by its pricing in Asia and Africa; its entry plans and 1-day passes are the cheap part, as our GigSky review explains. GigSky suits a Patagonia itinerary, a cruise around Cape Horn or a one-day pass on arrival.

eSIM4Travel eSIM in our hands

Go to eSIM4Travel website View full review

eSIM4Travel earns its place on price and on our hands-on test, not on Argentina reports: there are no traveler reports from Argentina yet, so nothing in the count says how it performs here. What the files do show is that it is the cheapest provider in our price comparison and had the best help desk we tested: a short bot, one click to a human, who solved the problem and added a tip on switching network. The eSIM installed from a QR code and worked right away. Across all countries its reports put it fourth most reliable, from a small sample.

With no Argentina reports there are no misses to describe. One thing to check before buying: its page is inconsistent about the network. The Argentina product is labelled "Movistar", the page body says the same, and the footer lists Claro as well, as of September 2026. It states 4G, LTE and 3G and no 5G. If Movistar is the network, the Tuenti transition applies here too.

What it sells here is the fullest small-plan ladder: 100 MB and 500 MB day plans, 1 GB for 1 or 7 days, 3 to 20 GB for 30 days and unlimited Argentina plans from 3 to 15 days, which its page says slow after 3 GB a day; day plans slow after their allowance. Regional "Latin America 10" and "Global 72" plans also cover Argentina. Plans activate on first connection, within 90 days of purchase, and a queued top-up starts when the current plan expires. The downsides are the ones we found in our test: no app, no Google Pay, a card typed in by hand, and no way to reach the shop without Wi-Fi once the data is gone. In our price analysis its edge is largest at small sizes and smaller in the Americas. Refunds are available within two months if under 10% of the data was used; our eSIM4Travel review has the help-desk transcript. eSIM4Travel suits a short trip with a few GB and a traveler who wants a person to talk to.

Jetpac eSIM in our hands

Go to Jetpac website View full review

Jetpac has a good Argentina record with a pattern inside it: it worked well for 6 of 7 travelers who reported from Argentina (86%), limited evidence, but several of the successes describe data that did not come up on landing and a WhatsApp help desk that fixed it within minutes, in November 2025, December 2025 and February 2026. "Messaged Jetpac over WhatsApp and in less than five minutes I was up and running fine," wrote one traveler in December 2025. The one miss is from November 2024: a multi-country eSIM that connected in Chile and never worked after the crossing into Argentina, with a chat that turned into requests for a good rating instead of a fix.

What it sells here: Argentina packs of 1 GB for 4 days, 3 GB for 7 days and 5 to 30 GB for 30 days, every one of them flagged 4G only in our comparison tool, plus Latin America and Global packs (the Global packs list 5G). No unlimited plan for Argentina. On packs of 3 GB and up, WhatsApp, Maps, Uber and Grab keep working after the data runs out, and the app sells voice packs. Its network is not named officially; two third-party sources, including a September 2026 field use, report Claro, which would be good news for Patagonia if confirmed. In our price analysis it is among the dearer providers for 3 to 20 GB, and its site and app were rough in our test, as our Jetpac review shows. Jetpac still makes sense for a traveler who values a responsive help desk over a polished app.

Airalo eSIM in our hands

Go to Airalo website View full review

Airalo is a fair choice for beginners who want calls and texts, not a top pick on its Argentina record: it worked well for 5 of 6 travelers who reported from Argentina (83%), limited evidence, with one working report from Iguazú (shared with Brazil). We do not have the text of the miss. One indirect signal in the reviews we read: a Ubigi customer in northern Argentina in July 2026 saw a companion with an Airalo eSIM keep a good connection where theirs showed none. Across all countries, though, Airalo has the lowest share of working reports of the 14 providers.

What it sells here: the "Abrazo!" Argentina family from 1 GB for 3 days to 20 GB, plus an unlimited plan that its page says slows after 3 GB a day, the Latamlink regional plan and the Discover and Discover+ global plans, the latter with calls, texts and a US number. Its page names Movistar as the primary network, as of September 2026, so the Tuenti transition applies. Some packages start on install rather than on first connection, so check the package page before installing at home. Purchase works in the browser without the app and installation needed no settings in our test. In our price analysis Airalo sits at the market average and is never the cheapest; the Airalo review covers the loyalty cashback and the eKYC checks some countries need. Airalo suits a first eSIM that must include a phone number.

Yesim eSIM in our hands

Go to Yesim website View full review

Yesim is for experienced users who want unlimited data sold by the day, and its record here is mixed: it worked well for 5 of 7 travelers who reported from Argentina (71%), limited evidence, and in Buenos Aires 1 of 2. We do not have the texts of the two misses. What we do know from our test is that the help desk was among the slowest we tested, 15 to 60 minutes per reply with template answers, so a problem on arrival may take a while to solve.

What it sells here is the broadest range after ByteSIM: Argentina unlimited plans for any length from 1 to 30 days (the fair-use limit is not published), fixed Argentina plans from 1 to 30 GB, a 200 MB day plan, Latin America and Global bundles, and an "Unlim Day Pass". Yesim did not name an Argentine network on its page when we checked in September 2026; it describes a "SwitchLess" multi-network setup. One trap: in our test the plan started at purchase, not at install, so buy close to the trip or use the "Activate later" option. In our price analysis its unlimited plans are at market and its fixed country plans are dear; details in our Yesim review. Yesim fits someone who knows eSIMs and wants a 4-day or 9-day unlimited plan that nobody else sells.

Ubigi is the travel eSIM brand of Paris operator Transatel, with one reusable eSIM for 200+ destinations. Data was fast in our test, and its 3 GB, 10 GB and 30-day unlimited plans are cheap. Its weak point is support: a chatbot that ends in an email ticket, with no live agent.

Ubigi eSIM in our hands

Go to Ubigi website View full review

Ubigi is hard to recommend for Argentina on the reports we have: it worked well for 1 of 3 travelers who reported from Argentina (33%), limited evidence, and the two misses are plain. One traveler in May 2026 reported no signal at all. Another in July 2026 had very bad coverage in Rosario and other cities. A third, also in July 2026, wrote: "Often only Edge in North Argentina (i.e. NO DATA)," while a companion on another eSIM stayed connected. All three reviewers were told to switch network manually, which is possible because Ubigi's partner list names both Movistar and Personal, as of September 2026; in our test the ticket we raised went unanswered for 24 hours, so expect to do that switch yourself.

What it sells here: Argentina plans of 1 GB for 7 days, 3 GB for 15 days, 10 GB for 7 or 30 days, 25 GB for 30 days and unlimited for 7 or 30 days (the research puts the fair-use point at about 20 GB), plus Americas, Best Latam and World plans. Two real strengths remain: Ubigi is one of only two providers here that document Personal, the operator every measurement series ranks first, and its "Zero Rating" let us reach checkout with no data left, so you can buy more without Wi-Fi. In our price analysis it is just below market, cheap at 3 and 10 GB. Our Ubigi review explains the clumsy website and app. Ubigi might still suit a tech-savvy traveler who will set the network to Personal by hand and does not expect help.

GoMoWorld is the travel eSIM brand of Irish operator eir, with plans in 202 countries. Every destination has the same four euro prices, and we saw no throttling at all. The catch is that everything happens in the app, and human support works only in office hours.

GoMoWorld eSIM in our hands

Go to GoMoWorld website View full review

GoMoWorld has too few Argentina reports to judge: it worked well for 1 of 2 travelers who reported from Argentina (50%). The texts we read are both complaints from early 2025. One traveler in February 2025 wrote: "3g when same towers have 4g. Loses signal easily." Another, in March 2025, had next to no reception in some cities and tourist spots, and switching network did not help. Both describe signal, not setup, which fits a provider that does not name its Argentine network on its page (checked September 2026) and whose plans our comparison tool lists as 4G.

What it sells here: Argentina plans of 1 GB for 7 days and 5, 10 or 15 GB for 30 days, plus a Latin America plan, no unlimited and no calls. GoMoWorld was the fastest provider in our test with no throttling, which says nothing about Argentine towers. The setup rule to know: the eSIM exists only in the app, one account serves one device, and you must press Start (or schedule a start) or nothing happens, the most common cause of "not working" we see. Humans at the help desk work office hours only. In our price analysis it sits below market, best at 5 GB and up; see our GoMoWorld review. GoMoWorld is an option for a heavy user in the cities who presses Start on arrival.

Nomad eSIM in our hands

Go to Nomad website View full review

Nomad has too few Argentina reports to judge: it worked well for 1 of 2 travelers who reported from Argentina (50%), and we do not have the texts. What places it here is our test: the AI bot looped on an APN question, timed out and never offered a human, with an email arriving ten minutes later. Across all countries Nomad's record matches the market average.

What it sells here: Argentina plans of 1 GB for 7 days and 3 to 20 GB for 30 days, listed as Movistar in our comparison tool, with 30 days to activate and add-on data available, plus Latin America and Global plans; no unlimited for Argentina. A third-party source names Movistar as its network, which we could not confirm on Nomad's own page. The app is fast and has a home-screen widget showing remaining data, a feature nobody else offers, and the QR code also comes by email. In our price analysis Nomad is slightly below market with the flattest profile across sizes; our Nomad review has the help desk transcript. Nomad suits an experienced user who will not need help.

Saily eSIM in our hands

Go to Saily website View full review

Saily has the best app and help desk we tested, and the thinnest Argentina record: it worked well for 0 of 1 travelers who reported from Argentina (0%), a single report from Buenos Aires, too few to judge and no basis for a verdict either way. We do not have the text. Saily did not name an Argentine network on its page when we checked in September 2026.

What it sells here: Argentina plans of 1 GB for 7 days and 3 to 20 GB for 30 days, plus Latin America and Global plans; no unlimited for Argentina. An optional US phone number with calls and texts can be added after an ID check, and the app includes a free VPN location and ad blocker. Installation is in-app with no QR code, the smoothest we tested, and the help desk reached a fast, polite human. The drawback is price: in our price analysis Saily is among the two most expensive providers in 14 of the 24 most popular destinations, as our Saily review shows. Saily suits a first-time eSIM user who values the app over the price.

ByteSIM eSIM in our hands

Go to ByteSIM website View full review

ByteSIM has no traveler reports from Argentina yet. Its page names Movistar, Claro and Personal as its networks, as of September 2026, which on paper is the widest network access of any provider here. What places it in this group is our test: checkout demanded a phone number and full postal address, the app threw install errors and auto-activation failed, and the 24/7 WhatsApp help desk did not reply within 15 minutes.

What it sells here is the biggest Argentina catalogue in our comparison tool: day plans of 500 MB, 1 GB and 2 GB a day, fixed plans from 3 to 50 GB, and unlimited plans (slowed, limit not stated), each at validities from 1 to 30 days, with longer validity costing more. No top-ups: you buy a new plan. ByteSIM accepts more than 50 local payment methods. In our price analysis it is at market, cheaper for short trips; the ByteSIM review describes the install errors. ByteSIM might suit an experienced user who wants three networks and can do a manual install.

Providers travelers report from Argentina that we have not tested

Simify, which we have not tested, also turns up in the Argentina reviews we read, with too few reports to judge: one traveler in April 2026 had coverage in most remote places on a Chile and Argentina trip but not in southern Patagonia, and another in November 2025 found it fast and steady in Buenos Aires.

Best eSIM Plans for Argentina

Price per GB in Argentina by eSIM Provider

How much does each provider charge per GB in Argentina? The chart below compares plans of 1 to 10 GB that last 6 to 14 days, the usual range for a one or two week trip. Provider websites show only their own plans, so this side-by-side view is one you would otherwise have to work out yourself. A shorter bar means a lower price per GB.

The tables below group every Argentina plan in our comparison tool by data size, with live prices. Unlimited plans for Argentina come from Maya Mobile (global), Holafly, Airalo, eSIM4Travel, Yesim, Ubigi and ByteSIM, plus GigSky's 1-day pass; Global YO, Roamless, Jetpac, Nomad, GoMoWorld and Saily sell fixed data only here. If Argentina is one stop on a longer South American trip, the multi-country search finds one plan for several countries at once; you can compare plans that cover both Argentina and Peru, and our Peru guide has the traveler reports for that country. For the size to pick, our guide on how much data you need for a trip works through the usual cases.

Best eSIM for Buenos Aires and Patagonia

Buenos Aires is the only place with enough reports for a pick of its own, and the pick is Maya Mobile, which worked for all 4 travelers who reported from the city. Patagonia is listed because the reports and the research both single it out; its rows are shared with Chile and do not add to the country total. Everywhere else the country pick applies.

Best eSIM for Buenos Aires

Maya Mobile is the pick for Buenos Aires because it is the only provider with 3 or more working reports from the city, 4 of 4, and the runners-up each have a miss or too few reports. GigSky's one Argentina miss was here, in a city where it worked for the other 2 travelers. Yesim split 1 of 2, and Saily's single Buenos Aires report did not work; we do not have the texts of those misses. Global YO (2 of 2) and Holafly (1 of 1) have clean but tiny records.

The city is the easy part of the country: urban Argentina is a normal 4G market with early 5G, and Personal, the operator with the best measured results, is strongest in the centre and north according to a September 2026 field account. For the arrival itself, the reports that mention the airport come from Jetpac customers whose data did not start on landing and was fixed over WhatsApp within minutes. If you land without a working eSIM, the Personal Flow store in the Ezeiza departure hall opposite check-in 40 sells SIMs by card only [1].

Best eSIM for Patagonia

No provider has 3 or more Patagonia reports, so the country pick, Maya Mobile, applies, with a caveat from the research: the south is where the network behind the eSIM matters most. The reports we have are all positive but few: Global YO worked for 2 of 2, and GigSky and Maya Mobile for 1 of 1 each, all shared with Chile. GigSky also has single working reports from Ushuaia and Bariloche, and a review the research records credits its network failover in Ushuaia. The Maya Mobile place-level reports that did not work came from El Calafate and northern Argentina.

The government tourism guide recommends Claro for Patagonia and ranks Personal third for coverage breadth [1], and a September 2026 field account found the same, with Personal's footprint much narrower in the south and Movistar the weakest overall. Of the providers here, none documents Claro alone: Jetpac is reported on Claro by two third-party sources, eSIM4Travel lists Claro in its footer but labels its product Movistar, and ByteSIM names all three. Holafly, Airalo and Roamless name Movistar or Telefónica. A reviewer of Simify, which we have not tested, in April 2026 had coverage almost everywhere on a Chile and Argentina loop except southern Patagonia. For a Ruta 40 or Ushuaia trip, the safest reading of the files is a provider with reports from the south (GigSky) or one that can switch networks by hand (Ubigi, ByteSIM), and offline maps regardless.

Local SIM Cards and Operator eSIMs in Argentina

A local SIM is cheaper than any travel eSIM once you need about 3 GB or more, and it includes local minutes, as of September 2026. A travel eSIM wins for a trip under 3 GB, or for anyone who wants data on landing without a store visit and a passport registration. All three operators sell a tourist prepaid product, and all three offer eSIM. Registration is mandatory, a passport is enough and no local address or tax number is required [1].

The prices below come from a third-party field guide dated 4 Sep 2026, which converts at roughly 1,500 pesos per US dollar; the operator pages were blocked or only rendered in the browser when we checked on 25 Sep 2026, so re-check at purchase. Personal's Turista Prepago, with 3 GB, 100 local minutes and 30 international minutes for 30 days, cost ARS 5,900 (about $4.00), with top-ups of 5 GB plus unlimited WhatsApp at ARS 10,000 and 10 GB at ARS 13,000 [9]. Claro's Chip Turista started at ARS 8,000 for 2 GB plus 500 MB for social apps and unlimited calls over 30 days, with 6 GB at ARS 10,600, 10 GB at ARS 15,000 and 15 GB at ARS 19,100; its tourist terms page still showed a July 2026 validity window on 25 Sep 2026 [5]. Movistar's welcome pack for new prepaid lines gave 10 GB plus WhatsApp, credit and calls for 30 days at ARS 8,000; Movistar registers passport details through a WhatsApp flow or in store [7]. One Claro clause to know: its prepaid terms auto-charge a 50 MB "Pack Conectado" at ARS 585 whenever the line has balance but no active data pack [6].

Where to buy: Personal Flow has two stores at Ezeiza, including one in the departure hall opposite check-in 40, card only, and no other operator sells there [1]. The government guide said in May 2025 that Personal also sold a tourist eSIM online with immediate activation; we could not re-check that on Personal's site. Claro sells in its own stores and resellers, and issues tourist eSIMs in store after a passport scan, according to a 2025 field account. Movistar sells through kiosks, supermarkets and stores. What to avoid: the friction documented in 2026 field accounts, where store registration took over an hour when something went wrong, a Claro store activated a line but left it without credit, and kiosks sold SIMs they could not register. We could not confirm whether taxes are included in list prices or whether the airport charges more; the Personal pack was quoted at the same price at Ezeiza and in the city.

Mobile Networks in Argentina

Personal is the best network on measured evidence and Claro the widest one in Patagonia and remote areas, and the files do not resolve that conflict, so both stand. Argentina has three national operators licensed by ENACOM, the telecoms regulator [3]: Personal (Telecom Argentina), Claro (América Móvil) and Movistar (Telefónica's former Argentine business, bought by Telecom in February 2025). Every independent measurement series we found puts Personal first: nPerf has ranked it first for five years running to March 2026, Opensignal's November 2023 report gave it the best download speed, coverage experience and consistent quality, and it has the largest 4G footprint by localities and the only 5G standalone cluster, according to the operator. Claro came second on every speed and quality measure but, according to the government tourism guide, has the widest signal including Patagonia [1], and 2026 field accounts agree. Movistar came last on speed, coverage and consistency in those series, though nPerf credits it with the best latency.

Which network your eSIM uses, as of September 2026: Ubigi and ByteSIM document Personal (ByteSIM all three operators); Airalo, Holafly, Roamless and eSIM4Travel name Movistar or Telefónica on their pages, with eSIM4Travel's footer also listing Claro; Jetpac is reported on Claro by two third-party sources, including a September 2026 field use; Nomad is listed as Movistar in our comparison tool but we could not confirm it; and Maya Mobile, Global YO, GigSky, Yesim, GoMoWorld and Saily do not name an Argentine network on their pages. The Movistar group is in transition. According to trade press reports from September 2026, the competition authority approved Metrotel to take over 6 million divested Movistar lines and 130 MHz of spectrum, trading as Tuenti, starting before the end of 2026 and roaming on Telecom's network at first. We re-check every network attribution at each update.

For the trip: 5G runs on the 3.5 GHz band at all three operators but is early-stage, so a 4G plan loses little; our guide on whether 5G is worth it explains why. We could not confirm a 2G or 3G shutdown date. Coverage maps: Claro's is an address lookup that shows predicted coverage [4], Movistar's exists only inside the Mi Movistar app [8], and we could not find a public Personal map. Road dead zones are unmapped; a bill introduced in the Buenos Aires provincial legislature on 4 Sep 2026 would build a map of them for ENACOM, but it has not passed. Provider pages do not say how to switch operator manually; our guide to eSIMs with several networks covers the phone settings that do it.

How to Set Up an eSIM for Argentina

Install at home on Wi-Fi, before you fly: almost every plan here starts on first connection in Argentina, not at install, and four in ten tourists cross a land border with no store in sight [2]. The exceptions from our tests: Yesim's plan started at purchase, GoMoWorld's does nothing until you press Start, GigSky's starts on first connection and cannot be paused, so keep it switched off until arrival, and some Airalo packages start on install.

1. Check that your phone is unlocked and eSIM-capable; our list of eSIM-capable phones covers the models. US-market iPhones are eSIM-only; most iPhones sold in mainland China lack eSIM.
2. Buy before departure and mind the activation window: eSIM4Travel plans must be activated within 90 days, Nomad's Argentina plans within 30 days, Saily's within 180 days, Ubigi's QR code is valid for 6 months and Jetpac keeps unactivated packs for 3 months.
3. Install on Wi-Fi. Maya Mobile, Airalo, Ubigi, Yesim, ByteSIM, Jetpac, Nomad, Holafly and eSIM4Travel send a QR code or install it from an email; GoMoWorld, Saily, Roamless, GigSky and Global YO install only through their app. Our guides for adding an eSIM on iPhone and adding an eSIM on Samsung show the screens.
4. Set the APN where the provider asks: "globaldata" for Maya Mobile and Global YO, "gigsky" for GigSky, "mobiledata" for Ubigi; for Roamless pick "Proximus Internet" if the preselected APN fails, as it did in our test.
5. On landing, turn on data roaming for the eSIM, set it as the data line, and switch the physical SIM off if data does not start; Jetpac's data dropped in our test until we did. If the network is weak, select another operator manually where the provider has more than one.
6. Still nothing? Our eSIM troubleshooting guide walks through the usual causes, and Jetpac's reports show that a WhatsApp message to the help desk solved landing trouble within minutes.

Calls and SMS in Argentina

Argentina's calling code is +54, and almost every travel eSIM here is data only, so calls go over WhatsApp or another app. The exceptions in the files: Airalo's Discover+ global plans include calls, texts and a US number; Saily sells an optional US number with minutes and SMS after an ID check; Jetpac sells voice packs in its app, though in our test the recipient saw a US number; Roamless and Global YO offer internet calls from the app, Roamless with an optional second number. ByteSIM sells local-number plans in some countries, but our comparison tool shows none for Argentina.

If you need a local Argentine number, a local SIM is the way: Personal's tourist pack includes 100 local and 30 international minutes and Claro's includes unlimited calls, with the prices and the passport registration in the local SIM section above. Some providers add an SMS-receive number on subscription plans (Holafly Plans, Saily Ultra, Yesim), which is enough for verification codes but not for calls.

Free eSIM Data for Argentina

Roamless lists a free Argentina plan in our comparison tool: 400 MB for new users, pay-as-you-go, with the 30-day trial clock starting at activation and no throttling claimed. That is enough to test the network on arrival or to run maps for a day. GigSky gives new users a free 100 MB trial, Nomad a free 1 GB trial, GoMoWorld a free one-day trial and Jetpac a 100 MB "Eterna" eSIM; the files do not confirm which of those cover Argentina, so check the provider's offer page. Our free eSIM data guide keeps the list current.

Summary: the best eSIM for Argentina

Based on 78 traveler reports and our tests, we recommend Maya Mobile for most trips to Argentina: it worked well for 20 of 21 travelers, including all 4 who reported from Buenos Aires, its unlimited plan was not capped from the start in our test, and its weakness is that it sells nothing for a one or two day trip. Holafly (8 of 8) is the safe choice for unlimited data with a one-tap install, with the stated drawback that its speed was capped from the start in our test. Global YO (5 of 5) is usually among the cheapest here, above all for big plans, with a slow help desk. Roamless (4 of 4) fits light users and multi-country trips with credit that never expires, but is dear from 10 GB up.

GigSky (11 of 12) is the one provider with reports from Ushuaia and Bariloche and sells cruise plans, at a high price overall. eSIM4Travel has no Argentina reports yet; it is the cheapest provider in our comparison with the best help desk we tested, and no app. With any of them, the research says the same thing: in Patagonia and the northwest the operator behind the eSIM decides, and a Movistar-based eSIM is riding a network in transition. For a trip under 3 GB or a landing without a store visit, the best eSIM for Argentina is one of the six above; for a long stay with heavy data, a Personal or Claro tourist SIM costs less.
