Of the three big travel eSIM brands, only Nomad sells a Cuba plan in 2026. It exists, it is on sale, and the catch lies elsewhere: in its price next to the state tourist line, and in the fact that every phone on the island shares one operator's masts. Airalo has no Cuba product page, and Holafly's Cuba address returns nothing either. That leaves two real options: Nomad, or a Cubacel Tur line from ETECSA, the state company that owns every tower, cable and public hotspot in the country.
Nomad lists three Cuba plans: 1 GB over seven days for US$21, 3 GB over thirty days for US$49 and 5 GB over thirty days for US$69, all on Cubacel. ETECSA's authorised distributors sell the Cubacel Tur Basic at US$13.99 for 4 GB, 20 minutes and 20 texts over a week. The Plus costs US$34.99 for 10 GB, 100 minutes, 100 texts and unlimited WhatsApp and Facebook over thirty days. That works out near three and a half dollars a gigabyte against fourteen to twenty-one on the eSIM. Nomad earns its fee for the hours between landing at José Martí and holding a Cubacel card, for a handset with no SIM tray, and as a spare line bought before you leave home, since US-issued cards and most payment apps do not work once you are inside Cuba.

Quick Pick: the Best eSIM for Cuba
Nomad (Cuba 1 GB / 7 days): The only major travel eSIM on sale for Cuba, listed on Cubacel 4G with tethering allowed. Buy the smallest plan before you fly as an arrival bridge and a spare, not as the data plan for the whole trip, because the Cubacel Tur Basic gives four times the data for less money.

Nomad Cuba Plans
Nomad: The Only Brand Selling Cuba, on ETECSA's Towers
Three data-only plans on Cubacel, from US$21
Nomad's Cuba range is short: 1 GB for seven days at US$21, 3 GB for thirty days at US$49 and 5 GB for thirty days at US$69. Per gigabyte that falls from US$21 to US$16.33 to US$13.80, so unlike Belize there is a real volume discount, but even the best rung costs about four times what ETECSA's distributors charge for a Cubacel Tur Basic. The plans are data only. You get no Cuban number, which rules out La Nave, the Havana ride-hailing app that wants a local or non-US phone number to register, and there is no unlimited tier.
What you pay for is timing and paperwork. Collecting a Cubacel Tur card means pre-ordering, matching the name to your passport, and finding the pickup point after an immigration and baggage process that can run to hours at José Martí. Nomad's profile is in the phone before you board. It also sidesteps Cuba's payment problem: you buy it at home on a card that works, and you are not trying to pay ETECSA in a country where US-issued cards fail and state offices favour UnionPay and Mir.
Be clear-eyed about the limits. Nomad rides Cubacel, so it shares every coverage gap and every blackout with the local card. A February 2026 test of foreign eSIMs in Havana recorded speeds around one megabit, well below the tourist SIM. We could not verify how Nomad specifically performs, and Nomad's app terms carry a standard clause about not being located in an embargoed country. Top up before you go rather than planning to do it from a Havana park bench.
Strengths
Weaknesses
Mobile Networks in Cuba
Cuba has one telecom company and no exceptions. ETECSA, the Empresa de Telecomunicaciones de Cuba, runs the fixed network, the international gateways, the WIFI_ETECSA public hotspots and, through its Cubacel brand, the only mobile network on the island. There is no second operator to switch to when one fails, no challenger undercutting prices, and no wholesale market for an eSIM reseller to shop around in. Every visitor's phone, whether it holds a Cubacel Tur card, a Nomad profile or a roaming line from home, ends up on the same Cubacel radio sites. Nomad's own plan listing names the network as C-COM, a legacy company name attached to network code 368 01, which is Cubacel today.
That single fact changes the advice this site normally gives. In Belize or Jamaica, carrying an eSIM next to a local card buys you a second network. In Cuba it buys a second billing relationship on the same towers. If a mast is dark, both lines are dark.
4G is real but partial, and there is no 5G
Cubacel switched on LTE in January 2019 on band 3 at 1800 MHz, then added band 1 at 2100 MHz and band 28 at 700 MHz in February 2023, with more than 800 new 2100 MHz cells announced across Havana, Matanzas including Varadero, and Cienfuegos. ETECSA itself says 4G is not yet present across the whole island and that a phone only reaches it inside covered zones. Nomad's page metadata advertises 4G and 5G, but its Cuba plans list 4G only, and no commercial 5G network operates in Cuba. A phone lacking band 3 will spend most of the trip on 3G.
The bigger problem in 2026 is electricity, not spectrum. Cuba's grid collapsed across the western half of the island on 4 March and nationwide again on 16 and 21 March, and a further nationwide failure began on 6 July. During the March event national internet traffic fell by about 65 percent and took around 29 hours to recover. In July ETECSA acknowledged a rise in mobile outages as roughly 47.5 percent of radio base stations and 56.5 percent of street cabinets went without power. Only about half of the country's roughly 2,520 radio sites have any backup at all. Recently installed solar packs give seven to eight hours, and an ETECSA official conceded in June that the network cannot run more than 24 hours without the grid. Havana's masts come back first and are generally the better-protected ones, but no SIM or eSIM sold anywhere can route around a tower with no power.
Two further constraints come from outside the island. US sanctions compliance means the Apple App Store, Google Play, PayPal, most banking apps and several streaming services refuse Cuban connections, so install apps and buy any extra eSIM data before departure. And while WhatsApp, Telegram and Signal generally work in 2026, the government has cut or throttled access during protests before. Reports of outages during unrest in June 2026 are a reminder that a political shutdown hits every line at once.
Coverage Across Cuba
Coverage where travelers actually go:
| Area | Coverage | Notes |
|---|---|---|
| Havana (Habana Vieja, Centro, Vedado) | Good | The core of the 2023 band expansion. 4G is normal across the old town, La Rampa and the Malecón, and service returns here first after a grid failure. |
| Varadero | Good | Named in the 2023 build of 2100 MHz cells. The hotel strip is covered, and the airport has its own Cubacel Tur pickup point. |
| Viñales and the road west | Fair | Usable 4G in the village centre. Expect 3G or no signal on long stretches of the drive out of Havana through Pinar del Río. |
| Trinidad and Cienfuegos | Fair | Central streets in both towns carry 4G. Coverage drops off quickly toward the Topes de Collantes hills and along the rural coast road. |
| Santiago de Cuba | Fair | Santiago province is on ETECSA's 4G list, but signal thins fast once you leave the city for the Sierra Maestra foothills. |
| Rural interior during blackouts | Unreliable | Away from towns 3G, 2G or nothing is normal, and sites without generators go silent when the local circuit is cut. |
How to Choose the Right Plan
Start from the fact that there is no network choice to make: everything is Cubacel, so you are choosing a price and a purchase route. For most trips of a week or more, pre-order Cubacel Tur Plus through an ETECSA distributor, collect it with your passport at José Martí or an ETECSA office, and enjoy 10 GB, a Cuban number and unlimited WhatsApp for US$34.99. For a short stay, Cubacel Tur Basic at US$13.99 for 4 GB over seven days does the same job for less. Add a Nomad 1 GB plan at US$21 if you will land late, face a long baggage wait, or cannot risk arriving with no way to message your casa. It is also the right primary choice for a single-day cruise call or a phone with no SIM tray. Americans should settle everything before boarding, because the card that paid for it will not work on the island. Whichever you choose, keep a few Nauta WiFi cards and a charged power bank in your bag. In Cuba the likeliest cause of losing your connection is a dark mast, and the only defence is backup, not a better plan.
Internet Restrictions in Cuba
A working data connection is not the same as a working internet connection. In Cuba, some independent news and messaging services are filtered or blocked.
What this means in practice
ETECSA is the only network and access is expensive and intermittent. Filtering matters less than simply getting a usable connection.
NordVPN
Obfuscated servers, which is the feature that matters in places where VPN protocols themselves are detected and blocked rather than just the sites.

Does Nomad's Cuba eSIM actually get a signal once I land?
It is on sale and it is built to: the plan listing attaches all three packages to Cubacel on 4G, and third-party comparisons published in 2026 describe it as working. Performance is the open question. One tester who ran several foreign eSIMs in Havana in February 2026 measured 0.4 to 1.1 Mbps, against 8 to 15 Mbps on a Cubacel Tur card in the same spots. That test did not isolate Nomad, and we have not run our own speed test on the island. Treat Nomad as a line that gets you messaging and maps on arrival, not as a guaranteed fast connection, and do not make it your only way to reach your casa particular.
I live in the United States. Can I buy and use a Cuba data plan?
The telecom purchase itself is covered. The US Treasury's Cuba rules at 31 CFR 515.542 authorise payments for prepaid, usage and roaming telecommunications services involving Cuba, including payments to ETECSA. The trip is a separate question, because a US traveller still needs to fit one of the twelve authorised travel categories, most often Support for the Cuban People. The practical catch is money: US-issued Visa, Mastercard and Amex cards do not process in Cuba at all, and payment apps are geoblocked there. Pay for Nomad, or pre-order a Cubacel Tur card from a distributor, before you leave. Nomad's app terms also include the standard app-store clause asking users to confirm they are not located in a US-embargoed country, so do not count on buying top-ups from inside Cuba.
Why does the state tourist SIM cost so much less per gigabyte?
Because ETECSA is selling its own capacity and Nomad is buying it second-hand. Cubacel Tur Basic is US$13.99 for 4 GB and Plus is US$34.99 for 10 GB, which is about US$3.50 a gigabyte either way, plus a Cuban number and minutes. Nomad's cheapest rate is US$13.80 a gigabyte on its 5 GB plan and US$21 on the 1 GB. There is no competing Cuban operator for a reseller to negotiate against, so the wholesale price Nomad pays reflects a monopoly selling to a foreign intermediary. The Plus package's unlimited WhatsApp also matters more here than in most countries, since that is how casas, drivers and guides communicate.
What happens to my data during a blackout?
It depends on whether the mast serving you has backup power, and neither your SIM nor your eSIM changes that. About half of Cuba's radio sites have generators or batteries, and new solar units last seven to eight hours. Routine scheduled cuts in Havana often leave mobile data running on backup. A national grid collapse like those of March and July 2026 takes a large share of sites offline within a day. Carry a charged power bank, download offline maps, and agree a meeting point with anyone you are travelling with before relying on a phone to find them.
Are Nauta WiFi cards worth buying if I already have mobile data?
As a cheap backup, yes. ETECSA's official price is 25 Cuban pesos for an hour and 125 for five, which comes to pennies at 2026 exchange rates. Hotels typically resell the same card at a steep markup. The cards log you onto WIFI_ETECSA hotspots in parks, plazas and hotel lobbies, and there are more than 1,245 of them nationwide. They do not escape the power problem, since hotspots run on the same grid, but they spread your risk across different equipment. Buy them from an ETECSA office rather than a park vendor, whose cards are sometimes already used.
Can one regional Caribbean eSIM cover Cuba along with other islands?
Do not assume so. Airalo and Holafly sell no Cuba country plan, so treat their Caribbean bundles as excluding Cuba unless Cuba is named on the product's own country list at checkout. If Cuba is one stop on a longer itinerary, the cleaner setup is a regional plan for the other islands and a separate arrangement for this leg. Our guide to an eSIM for a Caribbean island-hopping trip covers how to split that. Cruise passengers calling at Havana for a day are the one group for whom a small Nomad plan makes clear sense, since a Cubacel Tur collection trip eats the port call.
