Cuba eSIM
Cuba works differently from anywhere else in the region: mobile service comes from ETECSA, the state operator, and international roaming agreements are limited, so many visitors simply plan around being offline for parts of the day. Internet access is often bought by the hour in parks, hotel lobbies and ETECSA offices rather than assumed everywhere. A trip here goes far more smoothly when maps, tickets and the addresses of your casas are downloaded before you land.

How much data you actually need
Plan for far less than you would elsewhere. Many visitors get by on a few hundred megabytes a day for messages and maps, saving photo uploads and video calls for a Wi-Fi session in the evening.
When you land
José Martí International in Havana (HAV) is the main gateway, while resort arrivals land at Varadero (VRA), Holguín (HOG), Cayo Coco (CCC), Santa Clara (SNU) and Santiago de Cuba (SCU). Cuba is an island with no land border, so everything you need should already be downloaded before you board.
Where coverage changes
Havana, Varadero, Santiago de Cuba and the larger provincial towns have usable mobile data. It falls away in the Viñales valley, the Zapata swamp, the Sierra Maestra and along the long causeways out to the northern cays — and international sites can load slowly even where the signal bars look full.
Cities travellers ask about
- Havana — The easiest place in the country to get online.
- Varadero — Resort strip; most people lean on hotel Wi-Fi.
- Trinidad — Cobbled old town; best signal near the main square.
- Viñales — Tobacco valley; signal fades outside the village.
- Santiago de Cuba — Big eastern city with several ETECSA offices.
- Cienfuegos — Mid-sized port city, a common overnight stop.
Apps to install before you fly
- Offline maps downloaded in advance, such as Maps.me or Google Maps areas
- WhatsApp, which casa owners and locals use most
- A Nauta account from ETECSA for public Wi-Fi

Vanliga frågor
Can I use an eSIM in Cuba?+
We do not sell a Cuba plan, and roaming there depends on whether your own provider has an agreement with ETECSA, the state operator — many do not. Ask your home carrier what it charges before you fly, and expect to buy Wi-Fi time locally or use your accommodation connection for anything heavy.
How do people actually get online day to day?+
Mostly through the public Wi-Fi that ETECSA runs in parks, squares and hotel lobbies, logging in with a Nauta account bought by the hour. Evenings get crowded and speeds drop, so the practical move is to buy several hours while the queue is short and use them in one sitting when you really need to send something.
Should I warn people at home that I will be hard to reach?+
Strongly recommended. Agree on a window — for example a message every evening once you are back at the casa — and leave someone at home a rough itinerary with the name of each night stop. That way nobody panics when you go quiet for a whole day on a cross-country bus.
Do I need paper copies of my bookings?+
Keep both printouts and screenshots. Casa addresses, transfer times, your travel insurance number and intercity bus tickets should exist offline on the phone, because opening an email mid-journey may mean waiting for the next Wi-Fi point, which could be the following day.
When does a Cuba eSIM start counting days?+
Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.
Do I have to remove my home SIM?+
No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
