Cuba eSIM: Does It Work, What It Costs, and What Americans Need to Know
One state-run network, daily blackouts, no U.S. bank cards: how to stay online in Cuba, and what to set up before you fly.
- 1 mobile network: Cubacel, run by ETECSA
- 12 authorized categories of U.S. travel
- 0 U.S.-issued cards accepted on the island
- $120 for 10 GB over 30 days at Yesim
Short answer: yes, a travel eSIM can work in Cuba, but only through the island’s single mobile network, Cubacel, which belongs to the state telecom company ETECSA. Your eSIM provider buys access to that network; it does not bring its own.
We pulled this together from the U.S. State Department, the Treasury’s Office of Foreign Assets Control (OFAC), Canada’s travel advice for Cuba, Cuba’s official tourism portal and the providers’ own plan pages, all checked on October 23, 2026.
Before you book: the State Department asks Americans to exercise increased caution in Cuba because of crime and an unreliable power grid; read the current advisory. Canada went further on October 5, 2026, advising against all non-essential travel because of fuel, power and supply shortages.

Can Americans use an eSIM in Cuba?
The phone itself is not the issue; the trip is. OFAC’s Cuba guidance states that travel-related transactions are allowed only for 12 categories of activity, such as family visits, journalism, religious activities or support for the Cuban people, and that tourist travel remains prohibited.
Telecom is treated differently. The same guidance says U.S. persons may pay ETECSA directly for authorized telecom services, including activation, usage and roaming fees. OFAC’s FAQ we read is dated November 8, 2017, and Cuba rules have shifted with each administration, so confirm the current version on OFAC’s Cuba sanctions page before you go.
Money matters: Canada’s travel advice notes that cards issued by U.S. financial institutions are not accepted in Cuba. Buy your eSIM and enough data at home; topping up later needs both a working connection and a payment method.
How does a travel eSIM connect in Cuba?
ETECSA does not sell eSIMs itself, the independent Cuban outlet elTOQUE reported in 2025. Foreign providers reach the island through roaming deals with Cubacel, so speed and coverage are Cubacel’s whichever brand you pick. Some providers have dropped Cuba from their catalogs in the past, so check the provider’s Cuba page the day you buy, and install the eSIM before leaving: hotel WiFi may be too weak to download a profile.
Your U.S. carrier is another option only if it has a roaming agreement with ETECSA, as Cuba’s tourism portal points out. Call before you leave and ask for the Cuba rate.
Blackouts and spotty coverage: what to expect
- Power cuts are daily, long and unpredictable, per Canada; unplanned nationwide outages can last more than 24 hours.
- Cell service is unreliable and often drops when the power goes out. Internet access is limited island-wide and social media can be blocked during unrest.
- Backups: Canada recommends installing a VPN before departure and keeping paper copies of emergency contacts. Pack a charged power bank.
Free WiFi is limited but real: Cuba’s official tourism portal lists 30 free minutes in the arrival and departure lounges of 9 of the 10 international airports, plus WiFi in 255 hotels.
Cuba eSIM plans and prices
We only list providers selling a Cuba plan on the day we checked, with clear validity rules and visible prices. Prices were read on October 23, 2026 and change often.
| Yesim plan | Validity | Price |
|---|---|---|
| 1 GB | 30 days | $18.00 |
| 5 GB | 30 days | $66.00 |
| 10 GB | 30 days | $120.00 |
| Unlimited | 1 to 7 days | $31.20 a day |
Validity starts when the eSIM first connects to a network, and the plan must be activated within 180 days of purchase. Hotspot use depends on the network operator, and no Cuban phone number is included; WhatsApp and FaceTime calls run over data.

The CubacelTur tourist SIM
CubacelTur is ETECSA’s temporary line for visitors: 30 days from activation, with a starter bundle of data, minutes and texts. Cuba’s tourism portal lists two resellers for buying it before the trip, cubaceltur.com and recargasacuba.com, and ETECSA runs sales desks at the airports.
Its edge over an eSIM is a local number, handy for calling a casa particular, a driver or a restaurant. The catch: it must be picked up and activated on arrival, and paying there is hard without a usable card.
Pre-trip checklist
- Phone: carrier-unlocked and eSIM-capable.
- Gear: satellite phones are banned, and devices with GPS can be confiscated on entry and returned on departure, per Canada.
- Insurance: Cuba asks for proof of health insurance on arrival. OFAC’s guidance allows travel insurance for authorized travelers; confirm with your insurer that Cuba is covered, including medical evacuation.
- Records: OFAC requires authorized travelers to keep records of their Cuba trip for five years.
Our Cuba travel guide covers entry rules and regions. When choosing a place to stay, reviews often mention whether a hotel runs a generator: compare Havana hotels and recent reviews.
Cuba eSIM FAQ
Does an eSIM work in Cuba?
Yes, if the provider sells a Cuba plan. It roams on Cubacel, the only mobile network, so expect gaps outside cities and drops during blackouts.
Will my Verizon, AT&T or T-Mobile phone work in Cuba?
Only if your carrier has a roaming agreement with ETECSA. Ask for the Cuba rate before you leave; we could not verify each carrier’s current terms.
Can I pay for data in Cuba with a U.S. card?
No. Cards issued by U.S. financial institutions are not accepted in Cuba, according to Canada’s travel advice. Buy your eSIM and data before the trip.
Do I need a VPN in Cuba?
Canada advises installing one before departure, because access to the internet and social media can be restricted.
