Compare all eSIM plans in Serbia

How we got these numbers: we read 46 public customer reviews that mention Serbia or a place in it, published between August 2023 and August 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 9 of 10 means the eSIM worked well for 9 of the 10 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 Serbia, so it says how the provider behaves, not how the network performs here. Local operator prices in the text were checked on 18 September 2026; provider ratings, the plan tables and the price-per-GB chart are live and update on their own.

We ranked the providers on traveler reports from Serbia first, price second and our hands-on tests third. eSIM4Travel is in this group on price and on our test, not on reports, because nobody has reported from Serbia with it yet.

Maya Mobile eSIM in our hands

Go to Maya Mobile website View full review

Based on the reports, Maya Mobile is the best option for most trips to Serbia, above all for a week or more with heavy data use. It worked well for 7 of 7 travelers who reported from Serbia (100%), limited evidence, but the best record here among providers with more than 4 reports. The successes run from 2024 to 2025 and cover Serbia-only trips, Balkan road trips and long multi-country stays: one traveler used it in ten countries, including Serbia, Bosnia, Montenegro and Croatia, and several mention how easy it was to install. One reviewer in March 2024 summed it up: "worked great in Serbia and Bosnia".

None of the 7 reports from Serbia was a failure, but the texts carry two warnings. A motorcyclist on Maya's former Balkans package in July 2025 had it working in Serbia but not in Montenegro, Albania or Bosnia, with full bars and no data; Maya refunded him in full. A 3-star review from mid-2025 describes an unexpectedly large bill in the last hours of a Serbia plan. The review does not say what caused it, but in our test the purchase pushed Auto Top-Up, so that setting is worth checking before the trip.

Maya sells one product: a global unlimited plan for 3, 7, 14 or 30 days, plus a dearer Global + Cruise version, and nothing smaller. Maya lists Yettel (5G) and A1 (LTE) as its Serbian networks [9]. The plan terms in our comparison tool give full speed for 5 GB a day, then a slower speed, and our test matched that, with no throttling before the daily allowance. In our test the eSIM installed in about two minutes, but we had to set the APN ("globaldata") and data roaming ourselves, and the help desk took about nine minutes to reach a person. It is the cheapest global unlimited plan in our comparison, but poor value for a one- or two-day stay. The details are in our hands-on Maya Mobile test, and plans are on Maya Mobile's site.

Yesim eSIM in our hands

Go to Yesim website View full review

Yesim suits travelers who want unlimited data for an exact number of days in Serbia and rarely need help. It worked well for 4 of 4 travelers who reported from Serbia (100%), limited evidence. Our export of customer reviews holds no Yesim texts from Serbia, so we cannot say where those four trips went or what they had in common; the count is all we have.

With no failures reported, the warnings come from our own test. Our plan started at purchase rather than on arrival, so buying it the day before the flight is safer than weeks ahead. Its help desk was among the slowest we tested, at 15 to 60 minutes per reply, and the app stops working once the data runs out, so a top-up needs Wi-Fi.

Yesim's Serbia catalogue in our comparison tool has unlimited plans for every length from 1 to 30 days and fixed plans from 500 MB to 30 GB. Its Balkans plan covers Serbia plus ten nearby countries, among them Croatia, Bosnia, Montenegro, North Macedonia, Albania, Greece and Türkiye, which fits a regional road trip. Yesim's Serbia page names no network, only its "SwitchLess" multi-network system, and says unlimited plans follow each operator's fair-use rules and need no ID [10]. On price, its unlimited plans sit at the market average, while its fixed plans are usually above it. The full findings are in our Yesim test, and the Serbia plans are on Yesim's Serbia page.

ByteSIM eSIM in our hands

Go to ByteSIM website View full review

ByteSIM fits travelers who want a plan cut exactly to their trip and can live with a rough buying process. It worked well for 3 of 3 travelers who reported from Serbia (100%), limited evidence. The reports span August 2023 to June 2026: two Serbian reviewers called it flawless and fast, and a frequent traveler who used it in ten countries, Serbia among them, praised quick WhatsApp help when an activation stalled.

No traveler reported a failure. The open question is the network. ByteSIM's Serbia page named Yettel when checked in September 2026, but its page metadata still says VIP Mobile, the old name of A1 [11], and an earlier indexed version listed all three operators. Two of the three reports came before that switch, so they say little about the current setup.

Its Serbia catalogue is the largest in our comparison tool: daily plans of 500 MB, 1 GB or 2 GB a day, fixed plans of 3, 10, 20 and 30 GB, and unlimited plans, each for 1 to 30 days. ByteSIM's page lists 4G LTE, no ID check and a 180-day refund window for unused eSIMs, and says data slows to a crawl once the quota is used [11]. In our test the checkout asked for a phone number and a full postal address, our WhatsApp message got no reply within 15 minutes, and there are no top-ups. Prices sit around the market average, competitive for 3 to 5 GB on short trips. The test details are in our ByteSIM review, and plans are on ByteSIM's site.

Nomad eSIM in our hands

Go to Nomad website View full review

Nomad suits experienced travelers who can fix an installation themselves, and it has the broadest evidence of any provider in Serbia. It worked well for 9 of 10 travelers who reported from Serbia (90%), limited evidence, almost all of them from summer 2026. The successes include a ten-day Serbia trip, Balkan routes through Bosnia and North Macedonia, a traveler who has used it in Serbia several times, and one who tried Nomad's trial eSIM in Serbia.

The one failure, in May 2026, says only that the Serbia connection did not work. Two other trips worked in the end but needed effort: one traveler had trouble activating the eSIM twice, and another found that neither the install link nor the QR code worked, so they added the eSIM by hand with the activation code and set the APN manually. A reviewer on the Balkans regional plan found it good in the major cities of Serbia, North Macedonia and Croatia.

Nomad's Serbia page lists A1, Yettel and mts [12], while partner storefronts and our comparison tool show only A1 and Yettel, so the third network is not confirmed for every plan. Country plans run from 1 GB to 50 GB, with unlimited plans for 5 or 10 days that slow down after 2 GB a day, plus Balkans and global regional plans. In our test the help desk bot looped and gave no route to a person, so problems like the ones above are yours to solve. Prices sit slightly below the market average. The full test is in our Nomad review, and plans are on Nomad's site.

Ubigi eSIM in our hands

Go to Ubigi website View full review

Ubigi suits tech-savvy travelers who want Yettel's network and a generous unlimited plan. It worked well for 4 of 5 travelers who reported from Serbia (80%), limited evidence, all from April to July 2026. One reviewer called it very reliable as long as she restarted her phone after arriving, another had no interruption except a 3G connection in Serbia, and a couple on a five-country summer trip said it worked everywhere, including rural areas.

The miss was a traveler in July 2026 who could not connect at all during three days in Serbia, after the eSIM had worked in Hungary and Croatia. Ubigi's reply pointed to slow network registration after a border crossing and to its manual network-switching instructions. A second reviewer found Serbia left out of the plan they had bought for Eastern Europe, so the country list is worth checking before buying a regional plan.

Ubigi's Serbia page names Yettel and uses its Smartstart activation on arrival; the 7-day unlimited plan gives 20 GB at full speed, then a slower speed, and an unused plan expires after 6 months [13]. Country plans in our comparison tool come in 3, 10 and 25 GB, plus unlimited for 7 or 15 days, with no 5 GB or 20 GB step; Europe Extended and World plans also cover Serbia. In our test the app was the weakest we tried and our help desk ticket got no reply in 24 hours, but the eSIM let us buy more data at a zero balance. Prices sit slightly below the market average, and its unlimited plans are among the cheapest. The test details are in our Ubigi review, and plans are on Ubigi's site.

eSIM4Travel eSIM in our hands

Go to eSIM4Travel website View full review

eSIM4Travel earns its place on price and on our hands-on test. It is the cheapest provider in our comparison, and its Serbia plans of 2 to 10 GB undercut every other provider in our comparison tool at the time of writing. There are no traveler reports from Serbia for it yet, so we cannot say how it performs here; across all countries its record is the fourth best of the 14 providers, on a small sample.

In our test, run outside Serbia, the help desk was the best we tried: one click took us from the bot to a person, who solved the problem and suggested switching network. The eSIM arrived by email as a QR code and worked right away. The downsides are real: there is no app, no Google Pay, and once the data runs out you need Wi-Fi to buy more.

eSIM4Travel's Serbia page lists Telenor and Vip Mobile, the old names of Yettel and A1, and its country plans in our comparison tool carry the Telenor name [14]. Country plans run from 500 MB for a day to 50 GB for 30 days, with unlimited plans from 3 to 30 days that slow down after 3 GB a day, hotspot allowed, and 90 days to activate after purchase [14]. The Best Europe 41 plan also covers Serbia together with Croatia, Hungary, Bosnia, Montenegro, Romania, Bulgaria and Albania, but not North Macedonia. The full test is in our eSIM4Travel review, and plans are on eSIM4Travel's Serbia page.

Holafly suits travelers who want unlimited data on three networks and accept lower speeds. In our test its speed was capped from the start: enough for maps, messaging, browsing and video, but slow for large downloads, uploads, cloud backups and laptop work. It worked for 2 of 3 travelers who reported from Serbia (67%), limited evidence. Both successes came in June 2026 and describe constant coverage in remote parts of Serbia and on mountain roads; the miss was a Danube river cruise passenger whose Holafly Europe plan did not include Serbia.

Holafly's Serbia page lists A1, Yettel and Telekom Srbija (mts), unlimited plans from 1 to 90 days, a hotspot limit of 1 GB a day and no phone number, and it admits weaker coverage in the mountains [15]. There are no top-ups, so a longer stay means a new eSIM. Our comparison tool listed no Holafly plan for Serbia at the time of writing, so there is no plan table here. Its unlimited plans usually cost more than other providers' unlimited plans. The speed finding is in our Holafly test, and plans are on Holafly's Serbia page.

GoMoWorld is not a top pick for Serbia because half of its reports describe failures. It worked for 2 of 4 travelers who reported from Serbia (50%), limited evidence. In August 2026 a driver found the 4G "so slow that Google maps couldn't start properly", and the help desk told them GoMoWorld is not particularly strong in Serbia. In April 2026 another buyer never received the eSIM and got no reply from the help desk. The two successes were short reviews from trips that also took in North Macedonia and Türkiye, one praising the chat help desk.

Its Serbia plans in our comparison tool are 4 GB for 7 days and 15, 50 or 75 GB for 30 days, all 4G, hotspot allowed. Its Serbia page names no network, only "major Serbian networks", when checked in September 2026 [16]. In our test the eSIM came only through the app, never by email, and nothing worked until we pressed Start, a common cause of "not working" complaints. Our test also found no throttling at all, and the large plans are good value. The test details are in our GoMoWorld review, and plans are on GoMoWorld's site.

Airalo eSIM in our hands

Go to Airalo website View full review

Airalo had the weakest record in Serbia: it worked for only 1 of 4 travelers who reported from Serbia (25%), limited evidence, and all four reports came in June and July 2026. One traveler's eSIM would not connect at all, another found the service unusable as data trickled in and got only partial Airmoney credit back, and a third lost the connection for no clear reason and wrote "avoid in Serbia". The one success praised the speed but said the eSIM took 30 to 45 minutes to activate after landing at the airport.

Airalo's Serbia eSIM runs on A1 only [17], the operator with the smallest 4G area and no 3G fallback [1]; the reviews do not say whether that caused the failures. Plans run from 1 GB to 50 GB, with unlimited plans for 3 to 30 days that slow down after 3 GB a day, and the Eurolink and Discover regional plans also include Serbia. Airalo is priced at the market average, and across all countries its record is the lowest of the 14 providers in our traveler data.

Global YO is cheap and worked for everyone who reported, but two reports are too few to judge. It worked well for 2 of 2 travelers who reported from Serbia (100%): one in July 2024 had uninterrupted data from Belgrade up into the Zlatibor mountains and on into Bosnia and Montenegro, and one in January 2025 used it in Switzerland, Serbia and Albania. Neither reported a problem in Serbia; the only weak spot mentioned was at Tirana airport in Albania.

Global YO's Serbia page lists "Telenor srb." and "Vip", the old names of Yettel and A1, 4G/LTE only, no ID check and an APN that may need manual entry [18]. Country plans in our comparison tool run from 1 GB for 3 days to 100 GB for 60 days, plus day plans with a daily allowance, and the Europe Explorer and Global Explorer plans also include Serbia. It is the second cheapest provider in our comparison and gets cheaper as plans grow, but in our test the app was needed to buy, it stopped at 0 data, and the help desk replied slowly. The test details are in our Global YO review, and plans are on Global YO's Serbia page.

GigSky is a US travel eSIM that works like its own operator, with plans for 190+ destinations plus cruise, ferry and in-flight plans. Its app stays partly online after your data runs out. But its fixed-data plans are the most expensive of the 12 providers we compared.

GigSky eSIM in our hands

Go to GigSky website View full review

GigSky worked for both travelers who reported from Serbia, but its price keeps it out of the top group. It worked well for 2 of 2 travelers (100%), too few to judge: one in May 2026 found the signal a little spotty but working most of the time, and one in 2024 said it worked great in Serbia on a Balkan trip.

We could not confirm which Serbian network GigSky uses, because its Serbia page loads its content by script. Its Serbia plans in our comparison tool are 1, 3, 5 and 10 GB plus a 1-day unlimited pass, and its Europe, Cruise & Europe and World plans also include Serbia. The cruise plans matter on the Danube, where two travelers found Serbia missing from other providers' European plans. In our test the app stayed partly online after the data ran out, so we could buy more without Wi-Fi, and the help desk answered at once. It is among the most expensive providers in our comparison. The test details are in our GigSky review, and plans are on GigSky's Serbia page.

Saily eSIM in our hands

Go to Saily website View full review

Saily has the most polished app we tested, but too few reports from Serbia and a high price. It worked for 1 of 2 travelers who reported from Serbia (50%), too few to judge. The miss was on a Danube river cruise in May 2026: the traveler's European plan did not include Serbia, and in other countries the eSIM only connected after a phone restart. The other reviewer said setup took three minutes, against half an hour with the eSIMs they had used on earlier trips to Serbia.

Saily sells Serbia plans of 1 GB for 7 days and 3 to 20 GB for 30 days in our comparison tool, plus a Global plan that includes Serbia. Its Serbia page also lists unlimited plans and names no network, only "Serbia's best networks", when checked in September 2026 [19]. In our test the help desk reached a person quickly, but the app goes offline at 0 data. It is among the most expensive providers in our comparison and one of the two dearest in many popular destinations. The test details are in our Saily review, and plans are on Saily's Serbia page.

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. Its weak point is buying: the website forces you into the app, and large data amounts cost more than most rivals.

Roamless eSIM in our hands

Go to Roamless website View full review

Roamless has no traveler reports from Serbia yet, so it sits in this group despite a good record elsewhere: across all countries it was the third most reliable of the 14 providers in our traveler data. Its Serbia page names Yettel (3G/4G) and claims no speed limit, with 300 MB free for new users [20].

Plans in our comparison tool are 30-day Serbia plans from 1 GB to 50 GB, plus pay-as-you-go credit that never expires and works in other countries on the same eSIM. In our test the preselected APN did not work until we picked another one, the eSIM came only through the app, and a trickle of data kept working at a zero balance. It is cheap for 1 GB but expensive at 10 GB and above. The test details are in our Roamless review, and plans are on Roamless's Serbia page.

Jetpac is a Singapore eSIM provider with plans in 129 countries. It adds extras like in-app calls, free WhatsApp and Google Maps after your data runs out, and lounge access on delayed flights. Its website, app and support are rough, so it suits travelers who can fix small issues themselves.

Jetpac eSIM in our hands

Go to Jetpac website View full review

Jetpac has no traveler reports from Serbia yet. One review in our export, from June 2025, is a warning rather than a report: the traveler's Europe pack did not cover Serbia or North Macedonia, so a Balkan route needs Jetpac's Serbia or Global plan.

Jetpac's Serbia plans in our comparison tool run from 1 GB for 4 days to 40 GB for 30 days, all 4G only, and its Global plan also includes Serbia. Its Serbia page says packs of 3 GB or more keep WhatsApp chat, Google Maps and Uber working after the data runs out [21], and in our test it had in-app voice packs and free lounge access after a long flight delay. Its prices for 3 to 20 GB are above the market average, and our test found a rough app. The test details are in our Jetpac review, and plans are on Jetpac's site.

Best eSIM Plans for Serbia

Price per GB in Serbia by eSIM Provider

How much does each provider charge per GB in Serbia? 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 compare plans by size. Seven providers sell unlimited data that covers Serbia: Airalo, eSIM4Travel, Ubigi, Yesim, Nomad and ByteSIM have Serbia plans, Maya Mobile a global one, and GigSky a 1-day pass. Global YO, GoMoWorld, Roamless, Saily and Jetpac have no unlimited Serbia plan in our comparison tool. Not sure which size fits? Our guide to how much data a trip needs helps. Combining Serbia with the coast? Compare plans that cover both Serbia and Croatia.

Best eSIM for Belgrade, Zlatibor and Rural Serbia

No place in Serbia has 3 or more traveler reports yet, so the country picks apply everywhere. Maya Mobile, our overall pick, has no city-level reports; the table shows the two places that do.

Both entries come from one Global YO traveler in July 2024 who had uninterrupted data from Belgrade into the Zlatibor mountains. At Belgrade airport, the one Airalo success had to wait 30 to 45 minutes after landing before the eSIM came on, so installing at home and checking the connection on arrival is worth the effort; A1 also sells its tourist SIM in the terminal [3]. Away from the cities, 4G covers only 75% to 82% of Serbia's land, and mts has the widest 4G area of the three networks [1]. Holafly and Nomad list mts among their networks [15] [12], and two Holafly travelers praised its coverage in remote areas and on mountain roads, though its speed was capped from the start in our test. On a Danube river cruise, two travelers found Serbia missing from their European plans; a Serbia plan, a Balkans plan or GigSky's cruise plans avoid that gap.

Local SIM Cards and Operator eSIMs in Serbia

A Serbian tourist SIM gives far more data for the money than any travel eSIM, but it needs ID registration and covers little or nothing outside Serbia. All three operators sell a tourist product, and all prices below include VAT, as of September 2026 [3] [4].

• A1 Welcome SIM: 1,000 RSD (A1 shows about €8.27) for 200 GB over 7 days. A single top-up within the first week stretches it to 15 days (500 RSD or more) or 30 days (1,500 RSD or more). A1 also sells a 30-day speed-capped unlimited plan for 1,999 RSD. It is sold at the A1 point at Belgrade airport and in A1 stores, or online as an eSIM with the QR code by email; A1 says to register and activate it only after arrival, or the bonus is lost [3].
• Yettel Turistički paket: 1,399 RSD for 50 GB over 30 days, of which 3.5 GB also works in Bosnia, Montenegro, North Macedonia, Albania and Kosovo. You register the number, then send START by SMS to 9000 [4]. Yettel's page links to an eSIM purchase, which we could not test.
• mts Super Turist SIM: the Telekom Srbija group site lists €20 for 500 GB and unlimited calls to mts numbers over 30 days, as of September 2026 [5], while an mts announcement from August 2024 gave €15 for 200 GB, so the current price is worth confirming in store. It does not work in the Western Balkans roaming zone [5]. The same mts eSIM is resold online by Mobimatter with a Serbian number and an eKYC check (a quick online identity check) after purchase [22].

Registration is required by Serbian law for every prepaid number. A1 accepts a passport, or an ID card from the EU, Switzerland, Norway, Iceland, Montenegro, North Macedonia, Albania or Bosnia, and its online registration also asks for the PUK printed on the SIM holder [3]. According to Yettel and A1, an unregistered number can call only emergency services and the operator's own contact centre.

A local SIM beats a travel eSIM for a week or more in Serbia alone with heavy data use, or if you want a Serbian number. A travel eSIM is the better choice for short stays, for routes through neighbouring countries (where the mts SIM does not work and the Yettel SIM gives only a small share of its data), and for having data the moment you land.

Mobile Networks in Serbia

Serbia has three mobile networks, mts (Telekom Srbija), Yettel and A1, and for trips beyond the cities an eSIM that can use more than one of them gives the best odds. mts has the most sites and the widest 4G area, 82% of the territory at the end of 2025, against 78% for Yettel and 75% for A1 [1]. Yettel leads on crowd-sourced data: Opensignal named it Best Network for January to March 2026 and gave A1 the Best 5G Network award. The regulator RATEL's own drive tests ranked mts first in 2021, 2022 and 2023, according to RATEL's result posts, which we could not re-open; we found no newer RATEL campaign.

• mts: the largest grid, the widest 2G and 4G area and still a 3G network [1]; its own coverage map is public [7]. Holafly and Nomad list it among their networks [15] [12], and the only mts-only option we found is the local mts eSIM sold through Mobimatter [22].
• Yettel: keeps 3G on 900 MHz and has the widest 5G reach by population, mostly through DSS (dynamic spectrum sharing, which runs 5G on 4G frequencies and does not give full 5G speeds) [1]. Ubigi, Roamless and ByteSIM name Yettel alone [13] [20] [11], and Maya Mobile uses it for 5G [9].
• A1: the fastest 5G in Opensignal's data, but its 5G runs only on 3.5 GHz and covers a small part of the country, its 4G area is the smallest, and it has switched 3G off [1]. A1 describes its own coverage map as a propagation model [6]. Airalo uses A1 only [17].
• Several networks: Holafly lists all three [15], Nomad three on its own page and two elsewhere [12], and eSIM4Travel and Global YO list Yettel and A1 under their old names, Telenor and Vip [14] [18].
• Not named: Saily, Yesim, Jetpac and GoMoWorld named no network on their Serbia pages when checked in September 2026 [19] [10] [21] [16], and we could not confirm GigSky's.

For Belgrade, Novi Sad and other cities, any of the three networks is fine. For mountains and long drives, an eSIM on mts or on several networks has the most 4G area to work with, and one on A1 alone has the least, with no 3G to fall back on. If an eSIM lists more than one network but shows no data, selecting a different network by hand often helps; our guide to eSIMs with several networks shows how.

How to Set Up an eSIM for Serbia

Install the eSIM at home on Wi-Fi and switch it on when you land: almost every plan here starts only on its first connection in Serbia. The exceptions in our tests were Yesim, whose plan started at purchase, GoMoWorld, which needs you to press Start in the app, and some Airalo packages that start on install.

1. Check that your phone takes an eSIM and is not locked to your home carrier; our list of phones with eSIM helps.
2. Buy the plan and install it from the QR code or the app before you fly. Our guides for iPhone and Samsung show each screen.
3. On arrival, pick the eSIM as your mobile data line and turn on data roaming. Ubigi activates on arrival through its Smartstart feature [13].
4. No data? Restart the phone first: two Ubigi travelers and a Saily traveler only got a connection after a restart. Then check the APN; in our tests Maya Mobile and Global YO needed "globaldata" and Ubigi "mobiledata", and a Nomad traveler had to enter it by hand.
5. Still nothing? Select a network manually, which is what eSIM4Travel's help desk suggested in our test, then work through our eSIM troubleshooting guide.

Calls and SMS in Serbia

Most travel eSIMs for Serbia are data-only: none of the Serbia plans in our comparison tool include minutes or texts. Serbia's calling code is +381. For a Serbian number, the options are a local tourist SIM (see the local SIM section above) or the mts eSIM resold by Mobimatter, which includes unlimited calls to mts numbers and free incoming calls and texts, but no outgoing texts [22].

For everything else, app calling over data works on any of these eSIMs. In our tests, Global YO has outgoing calls over the internet, Roamless has in-app calls and an optional second number, Jetpac sells in-app voice packs, and Saily sells a US number as an add-on. Jetpac also keeps WhatsApp chat working after the data runs out on packs of 3 GB or more [21].

Free eSIM Data for Serbia

Three providers let you try Serbia data for free before paying. GoMoWorld's Serbia page lists a free 1 GB trial for one day [16], and Roamless gives new users 300 MB [20]. Nomad has a free 1 GB trial, and one traveler in May 2026 said the trial eSIM worked very well in Serbia. More options are in our guide to free eSIM data.

Summary: the best eSIM for Serbia

Maya Mobile had the best record, working well for 7 of 7 travelers who reported from Serbia, and suits trips of a week or more; it sells only unlimited plans and pushes Auto Top-Up at checkout. Yesim (4 of 4) fits travelers who want unlimited data by the day, but its help desk was slow in our test and the plan can start at purchase. ByteSIM (3 of 3) has the widest choice of Serbia plans behind a clumsy checkout. Nomad (9 of 10) has the most reports, but we found no route to a person on its help desk. Ubigi (4 of 5) runs on Yettel, though one traveler never connected and others needed a restart. eSIM4Travel is the cheapest in our comparison with the best help desk we tested, but has no app and no reports from Serbia yet.

Whichever provider you lean towards, check that Serbia is on the plan's country list, since several "Europe" plans leave it out. Combining Serbia with neighbours? Our guides for Croatia, Turkey and Greece cover the next stops. Based on 46 traveler reports and our tests, the best eSIM for Serbia in 2026 is Maya Mobile for most trips, with eSIM4Travel the pick on price.
