The best eSIM for Cuba is harder to pick than for most countries, because the island has one mobile network and the traveler data is thin. ETECSA, sold under the Cubacel brand, is the only operator, so every eSIM that works in Cuba roams on it and no provider can switch you to a second network. As far as we could confirm, ETECSA sells visitors physical SIMs only, so a travel eSIM is a roaming plan, not a local line.
Coverage and power are the main gaps. According to ETECSA's president in June 2025, 4G reaches about half of the population and half of the territory, and rural and mountain areas are weak. Cuban press reports citing ETECSA say about 47.5% of cell sites stop giving coverage during blackouts, and the network cannot run more than 24 hours without grid power. The communications ministry (MINCOM) published a plan to replace 1,075 battery banks and said more than 60% of provincial sites lacked backup power [1].
We found 23 traveler reports from Cuba, spread over four providers, so the evidence is limited. Only Yesim has a clean record. ETECSA runs tourist SIM counters at the main airports, and a local Cubacel Tur SIM cost less per GB than any eSIM in our research. According to Yesim's own blog, US-issued payment cards do not work in Cuba, so an eSIM has to be bought before you fly.

How we got these numbers: we read 23 public customer reviews that mention Cuba or a place in it, published between January 2025 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 11 of 11 means the eSIM worked well for 11 of the 11 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 Cuba, so it says how the provider behaves, not how the network performs here. Local operator prices in the text carry their own dates and were last reviewed on 25 September 2026; provider ratings, the plan tables and the price-per-GB chart are live and update on their own.

We chose the Best group by traveler reports first, price second and our own tests third. Only three providers have 3 or more traveler reports from Cuba, so this group has three entries instead of the usual four to six, and only the first has a good record.

Yesim is a Swiss eSIM provider built around unlimited plans sold by the day, with one eSIM for 200+ destinations. Data was fast in our test. But its support was among the slowest we have tested, and its fixed-data country plans cost more than most rivals.

Among the slowest support we've testedPricey fixed-data country plansNo top-up once your data runs outSigns you up for marketing emailsYesim eSIM in our hands
Yesim had the best record in the traveler reports from Cuba, and it is the best option here for travelers who can live with slow support. It worked well for 11 of 11 travelers who reported from Cuba (100%), which is a limited sample, and the reports do not say which cities or trip types they cover. With no misses to read, the record shows that Yesim connected, not where it worked or how fast.
Yesim's Cuba pricing is the thing to watch. Prices for the same plans differed between checks of its Cuba page in our research, so the live plan table below is the reference. Our test also found that a Yesim plan started at purchase, not at first connection, so buying close to the trip protects the days you pay for. Yesim has an "Activate later" option, which we did not test in Cuba.
Yesim sells Cuba-only plans of 1, 5 and 10 GB valid for 30 days, plus unlimited day plans from 1 to 7 days. The unlimited plans are throttled under a fair-use rule Yesim does not publish, and hotspot (sharing your data with a laptop) depends on the operator [5]. Its page lists 10 Cuban cities, allows activation up to 180 days after purchase and asks for no ID [5]. The plan page names no network; Yesim's own blog calls it Cubacel. On the prices recorded in September 2026, its 10 GB plan was the cheapest per GB of the eSIM plans we compared, while the unlimited day plans cost far more per day. Yesim is data only. Support was among the slowest we tested, with replies taking up to an hour, and our Yesim review has the details. Yesim suits travelers who install at home and want the cleanest Cuba record, with slow support as the main drawback. Plans are on Yesim's Cuba 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.

Pros and cons
One eSIM for 200+ destinationsFast, no throttlingWorked for 91% of travelersFree 500 MB trialWebsite pushes you into the appWe had to fix the APN to get dataCredit can expire after 12 monthsPricey for 10 GB and upRoamless eSIM in our hands
Roamless is the option for travelers who want to try a free Cuba plan first, but its record here is mixed: it worked for 1 of 3 travelers who reported from Cuba (33%), a limited sample. The two misses were a phone that showed signal but could not reach the internet (2 Nov 2025) and a one-line report that the service does not work in Cuba, filed with a billing complaint (17 Jul 2026). The one success is a five-star line, "It works in Cuba!" (21 Dec 2025), with no city named.
The November 2025 miss is the useful one. The phone showed full bars on 3G, 4G and LTE but could not get online. Roamless replied that the traveler had bought with one email address, then signed in to the app with an Apple ID, which created a second account, so the eSIM was not linked to the plan. Roamless refunded the purchase. If that explanation holds, the failure was an account problem, not a Cuban network problem. Our own test in Czechia showed a similar symptom: the preselected APN (the setting that tells the phone which data gateway to use) did not work until we chose another.
Roamless sells Cuba-only plans of 1, 2, 3 and 5 GB valid for 30 days after activation, pay-as-you-go credit that does not expire, and a small free plan for new users, which its page puts at 100 MB [4]. The page names the network as Cubacell, 3G and 4G, and says hotspot is unlimited and the plan activates on first use [4]. The eSIM is delivered only inside the app, so the app has to be installed before you fly. In our test, support reached a human in about half an hour, and the app keeps a trickle of data at zero balance. On price, Roamless was among the cheaper options per GB in our Cuba comparison, second only to Yesim's 10 GB plan. The main drawback is the record. Our Roamless review has the test details, and plans are on Roamless's Cuba 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.

Pros and cons
Buy more data even with none leftCruise, ferry and in-flight plansHuman support answered right awayCheap 1-day unlimited passesMost expensive per GB we trackApp required, no Google PayClunky, web-like appLess reliable than averageGigSky eSIM in our hands
GigSky has the second most reports from Cuba in our data, and most are bad: it worked for 2 of 8 travelers who reported from Cuba (25%), so the record is poor. It is in the Best group only because it has enough reports to judge. In Havana it worked for 1 of 4 travelers, and the single reports from Trinidad and Varadero were both misses. The two successes name no city: a five-star line from April 2025, and a three-star review from 7 Mar 2025 saying the last 3 GB did not last a day.
The six misses share one pattern: service that worked at first and then stopped, or never arrived. A traveler in January 2026 connected on landing in Havana, then estimated GigSky worked about 10% of the time around the island, while a local physical SIM worked about 90%. Another had service in Havana from 11 to 14 Jan 2025 and none for the rest of the stay, including Trinidad, and was told afterward that GigSky could only troubleshoot while the traveler was still in Cuba. A traveler and a companion on 5 GB plans in December 2024 saw the network appear after 15 to 20 minutes but got no data or calls for 24 hours, and GigSky refunded both. One traveler could not connect for more than 3 days with data left on the plan, and another said it did not work well at all, without detail. One review says "If you travel outside Havana, there's hardly any connection" (4 Apr 2025).
Our comparison tool lists GigSky Cuba plans of 1 GB and 3 GB valid for 15 days and 5 GB valid for 30 days, data only. GigSky's Cuba page was live in our September 2026 check, but its plan details did not load [6], and prices differ between our sources, so the live plan table is the reference. GigSky's own blog names Cubacel as the network. GigSky is the most expensive provider overall in our comparison; Cuba is not one of the destinations the price analysis breaks out, and in our Cuba per-GB check its 5 GB plan sat mid-table. In our test, GigSky's app stays partly online after data runs out, so you can buy a new plan without Wi-Fi, and its help desk answered at once. The app is required to buy, and there is no Google Pay. GigSky suits a traveler who accepts the record and wants the offline top-up, and the record is its main drawback. Our GigSky review has the test details, and plans are on GigSky's Cuba page.

Airalo is not a pick for Cuba because it appears to have dropped its Cuba plans. It has one traveler report from Cuba, a four-star review from July 2026 that counts as worked even though its text says Airalo used to work in Cuba and later stopped, so one report is too few to judge.
We found no Cuba plan on Airalo's site or in our comparison tool, and we could not read the country list on its Caribbean regional page. A third-party guide reports that Airalo dropped Cuba around the end of July 2024 without notice; we could not confirm that on airalo.com. Airalo is the biggest marketplace in our tests and easy to buy from, but it has the weakest traveler-report record of the 14 providers overall. Readers who want Airalo for other countries can read our Airalo review, and Airalo's homepage shows whether Cuba has returned.

eSIM4Travel is usually the cheapest provider in our comparison, but Cuba is a place where that does not hold, which is why it sits in this group. There are no traveler reports from Cuba yet, so we cannot say how it performs on the island.
Its Cuba page names ETECSA as the network and lists 1 GB plans for 1 and 7 days and a 3 GB plan for 30 days, data only, with hotspot allowed. Validity starts when the eSIM first connects to a network, and the eSIM has to be activated within 90 days of purchase [2]. In our Cuba per-GB check, its 3 GB plan was the dearest of the verified eSIM plans, and our comparison tool lists nothing larger than 3 GB from it. Our test found the best help desk of the 14 providers (one click from the bot to a human) and no app, which means you need Wi-Fi to reach the store once data runs out, and no Google Pay. eSIM4Travel suits small, short Cuba needs where human support matters.

Global YO is the second cheapest provider overall in our comparison, but we could not confirm that it sells Cuba, and there are no traveler reports from Cuba yet. Our comparison tool lists Cuba plans from Global YO, yet we found no official Cuba plan page in our research. Global YO's own travel guide says ETECSA has issued eSIMs since 2020, a claim that other sources contradict.
The tool lists 1 GB for 3 days, 3 and 5 GB for 15 days, 10 and 20 GB for 30 days, and day plans of 3, 7, 15 and 30 days that are flagged as throttled (the daily allowance is listed as 1 GB in one field and 3 GB in another). In our test, Global YO needed its app to buy, the app stops working at zero data, support was slow, and it has outgoing VoIP calls. It suits price-driven travelers who install at home, once Cuba is confirmed. See our Global YO review or Global YO's Cuba page.

Nomad is a US travel eSIM brand run by LotusFlare, with plans for more than 200 destinations. It has a polished native app, fast data and prices close to the market average almost everywhere. Its weak spot is support: the chat is an AI bot with no route to a human.

Nomad sells Cuba plans, but there are no traveler reports from Cuba yet, so we cannot say how they perform. Its Cuba plans are 1 GB for 7 days and 3 GB or 5 GB for 30 days, and its page labels the network C-COM (Empresa de Telecomunicaciones Celulares del Caribe SA) [3]. According to Wikipedia, C-COM was merged into ETECSA in 2003, so the label is an old name for the same single network.
The plans are 4G, allow hotspot, and have add-on data on some plans. Our comparison tool flags no throttling. On price, Nomad is slightly below the market average overall, and in our Cuba per-GB check its 5 GB plan came out mid-table, cheaper than GigSky's and eSIM4Travel's. The main drawback is support: in our test the chat bot looped and offered no route to a human. Nomad suits experienced travelers who will not need the help desk. See our Nomad review or Nomad's homepage.

Holafly is an Irish eSIM provider built around unlimited data, with trip eSIMs for 200+ destinations. Travelers report it working more often than any other provider we track. Its weak points are speed and price: our test ran at about 30 Mbps on 5G, and its unlimited plans cost more than most.

Pros and cons

Holafly does not sell a Cuba eSIM. Its own blog says it has none and is working on one, and its travel-insurance page says its eSIM does not work in Cuba. There are no traveler reports from Cuba yet. If Cuba is added, note that in our test Holafly's speed was capped from the start. That is enough for maps, messaging, browsing and streaming, but slow for large downloads, uploads, cloud backups and laptop work. Its hotspot is limited to 1 GB a day, and it has no top-ups.
Holafly's blog, updated in May 2026, says your home carrier's plan can work in Cuba only if the carrier has an ETECSA roaming agreement, and it lists several Spanish and Chilean operators that do. That is worth a call to your carrier before you buy any eSIM. Our Holafly review has the test details, and its homepage is Holafly.

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.

ByteSIM is a Hong Kong eSIM shop with a huge catalog: daily, fixed and unlimited plans for about 200 destinations. Data was fast in our test, and travelers report it working in 88% of cases. The checkout, the app and support were the weak points.

Our comparison tool lists ByteSIM plans for Cuba, but we found no official Cuba page (the plans showed up only on comparison sites we do not use), and there are no traveler reports from Cuba yet. We could not confirm that ByteSIM sells Cuba.
The tool lists 1 GB a day for 1, 3, 5, 7, 10 and 15 days, 1 GB for 7 days, 2 GB for 15 days, and 3, 5, 10 and 20 GB for 30 days, with no network named. ByteSIM has no top-ups. In our test its checkout and app were clumsy, and WhatsApp support did not reply within 15 minutes, although customers report fast replies. It suits experienced travelers once Cuba is confirmed.

Saily is the travel eSIM from the company behind NordVPN, with plans for about 200 destinations. It has the smoothest install we have tested, a polished app and a built-in VPN. But prices run above the market in most big European destinations, and traveler reports sit below average.

Saily does not list Cuba: its Caribbean Islands page leaves Cuba out [7], and our comparison tool lists no Cuba plan. There are no traveler reports from Cuba yet, and a third-party review from June 2026 agrees that Saily has no Cuba plan.
In our test, Saily had the most polished app, install and help desk, but it is among the dearest providers in the places most travelers go. Our Saily review covers it, and its homepage is Saily.
Best eSIM Plans for Cuba
Price per GB in Cuba by eSIM Provider
How much does each provider charge per GB in Cuba? 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 calculate yourself. A shorter bar means a lower price per GB.

Best eSIM for Havana, Varadero and Trinidad
The overall pick, Yesim, has no traveler reports tied to a named Cuban city, so the table below shows the only provider with city reports.
| Where you are going | What the reports show | Our pick |
|---|---|---|
| Havana | GigSky 1/3 | Country pick applies, no provider has a good record here |
| Trinidad | too few reports | Country pick applies |
| Varadero | too few reports | Country pick applies |
Best eSIM for Havana
No provider has a record we can recommend for Havana from city-level reports, so the country pick applies. The only reports that name the city are for GigSky, and one of three worked. One traveler got a connection on landing in Havana that was the best of the trip, a second called coverage in the capital itself "not great", and a third had service for the first days in Havana and then none for the rest of the stay.
The same traveler reports show the problem is bigger outside the capital. In Trinidad and Varadero, the one report each described no usable service, and a reviewer who left Havana for the rest of the island said the eSIM worked about a tenth of the time. That traveler bought a physical SIM and said the queues at the airport and in resorts were long, so plan on an hour if you go that route. Because Cuba has a single network, a second provider will not fix a dead spot; what changes is the plan and how it activates.
Local SIM Cards and Operator eSIMs in Cuba
ETECSA sells a tourist prepaid line called Cubacel Tur, and it is a physical SIM only; we found no eSIM from ETECSA itself. Cuban press reported two packages in December 2024: Tur Básico with 4 GB, 20 minutes and 20 SMS for 7 days at US$13.99, and Tur Plus with 10 GB, 100 minutes, 100 SMS and unlimited WhatsApp and Facebook for 30 days at US$34.99. Those prices come from press reports and third-party sellers, and ETECSA's own English page still lists an older 6 GB version of Plus, so confirm at the counter. Minutes and SMS work for national and international traffic, and the line can be extended up to 90 days with top-ups.
ETECSA tourist counters are at Havana's José Martí airport (Terminal 3, Hall C is open around the clock), and at Varadero, Camagüey, Holguín, Cayo Coco and Santiago de Cuba, and at ETECSA commercial offices. You need a foreign passport, buyers must be 18 or older, and resellers say the limit is 3 active lines. ETECSA says its counters take UnionPay and Mir cards, while Visa and Mastercard work only through international distributors, and US-issued cards do not work in Cuba, so carry cash. Resellers abroad who pre-sell the SIM add a markup; we saw about €30 to €35 for Plus. Activation is by dialling *666. Airport queues can take an hour, according to a GigSky reviewer who bought a physical SIM after the eSIM failed.
A local SIM beats a travel eSIM for stays of a week or more, heavy data use or any need for calls and SMS, because no eSIM we checked is cheaper per GB, and none includes minutes. A travel eSIM wins when you want data working on landing, a stay of a few days, or no queue and no SIM swap, and our reports show that wins only if the eSIM actually connects.
Mobile Networks in Cuba
Cuba has one mobile network, ETECSA, sold under the Cubacel brand, so there is no second operator to roam on. Every provider that sells Cuba uses it. The names vary: eSIM4Travel says ETECSA [2], Roamless says Cubacell [4], and Nomad uses C-COM [3], the name of a company merged into ETECSA in 2003. We could verify the network from the provider's own page for eSIM4Travel, Nomad and Roamless; Yesim's plan page does not name it, but its blog says Cubacel, and GigSky's blog does too. None of them documents a direct deal with ETECSA, so they roam.
Coverage is the limit. ETECSA's president said in June 2025 that 4G reaches about half of the population and half of the territory, and Cuban press reports 4G in all of Havana and in the provincial capitals. Rural and mountain areas are weak. Reports from Cuban press say that 3G runs on 900 and 2100 MHz, that 4G is on several bands, and that there is no 5G; we found no announced 3G shutdown. Independent speed data is thin: Ookla dropped Cuba from its index in July 2024, according to CubaNet.
Power matters as much as signal. ETECSA has said that about 47.5% of its radio sites stop giving coverage in blackouts, and MINCOM says more than 60% of provincial sites lacked backup power [1]. Press reports named Villa Clara, Santiago de Cuba and the Isla de la Juventud, which lost service for more than 5 days in September 2026, as weak spots. For a trip, this means a dead eSIM can be a dead network rather than a dead plan, so keep a Wi-Fi fallback and offline maps. Our reports back this up: one GigSky traveler's service stopped for the rest of the stay after the first days.
How to Set Up an eSIM for Cuba
- Check that your phone is unlocked and has eSIM; our guide to phones with eSIM support lists models.
- Buy and install the eSIM at home on Wi-Fi, because Cuba has little reliable public internet. eSIM4Travel says its eSIM must be activated within 90 days of purchase [2], and Yesim says 180 days [5].
- Follow the steps for your phone: iPhone or Samsung. Save the QR code or activation details in case you must reinstall.
- On arrival, turn on the eSIM line and data roaming for it. Roamless says its plan activates on arrival [4]; for the others, check on the plan page when validity starts.
- If it shows a signal but no data, check the APN and roaming settings, then restart. Our troubleshooting guide covers the common causes.
- Install any VPN or apps you need before you fly: Yesim's blog says the App Store can be unreachable in Cuba without a VPN already set up, and that text codes sent to foreign numbers are unreliable.
Calls and SMS in Cuba
Cuba's calling code is +53. None of the Cuba plans in our data include voice or SMS, so calls from a travel eSIM go over an app like WhatsApp. WhatsApp, Signal and Telegram were blocked nationwide in July 2021, according to Yesim's blog, so test your app on arrival. If you need a Cuban number, minutes or SMS, the Cubacel Tur local SIM in the section above includes them, and it is the only option in this article that does.
Free eSIM Data for Cuba
Roamless lists a free 100 MB trial plan for Cuba that is valid for 30 days [4]. That is enough to confirm the eSIM installs and connects before you pay for more, but not for real use. Our guide to free eSIM data plans and trials lists the others.

Summary: the best eSIM for Cuba
Yesim had the best record in Cuba, with 11 of 11 traveler reports saying it worked, though support was slow and its unlimited plans are throttled under a fair-use rule. Roamless is the one to start with if you want a free trial plan to test first, but only 1 of 3 reports said it worked. GigSky lets you top up without Wi-Fi, but only 2 of 8 reports said it worked, and the misses describe service that dropped after a few days or outside Havana.
With one network, thin 4G coverage and blackouts, no eSIM is a sure thing here, and the ETECSA tourist SIM is cheaper and includes calls. If you still want data on landing, the best eSIM for Cuba on our evidence is Yesim, and the live Cuba plan comparison shows what each costs today.
