Best SIM and eSIM for Cuba: data plans, Wi-Fi and phone tips

Match the option to how much you need to be reachable. If you only need maps and messages, an ETECSA tourist SIM with a small data top-up is enough. If you must stay online for work, budget for hotel Wi-Fi and a backup plan, because no single option is dependable.

Do the setup work at home, on fast Wi-Fi. Download offline maps for Havana, Trinidad and any other stop, save your bookings and tickets as PDFs, and download offline Spanish for your translation app. Screenshot your accommodation address and phone number; casa owners and drivers often use WhatsApp, so have that installed and your number confirmed.

Install and test a VPN before departure. Some services are blocked or unreliable on Cuban networks, and a VPN that has never connected once is hard to debug from a hotel lobby. Also check whether your phone is carrier-unlocked: an ETECSA SIM is useless in a locked handset.

Finally, tell people at home that you may go quiet. If your bank or airline sends verification codes by SMS, arrange an alternative before you leave, because roaming texts may not arrive.

ETECSA is the only operator, so every local SIM, top-up and hotspot account comes from the same company. Tourist SIMs are sold at the airport and at ETECSA offices in cities, and you need your passport to register. Airport counters are convenient but can be slow when a flight lands; city offices may be quieter but keep limited hours, so check before you walk across town.

Tourist plans are priced above what locals pay, and data is sold in bundles that expire. Buy the smallest bundle that covers messaging and map lookups, then top up if you need more. Keep the SIM card and the receipt: you may need both to add credit later. If you are offered an eSIM instead of a plastic card, ask to see it activate on your phone before you leave the counter.

Top-ups are usually bought as scratch cards or over the counter. Photograph the card and the code as soon as you buy it, because the printing rubs off.

Expect 3G and some 4G in Havana and the provincial cities, with coverage thinning fast outside them. Rural roads, mountain areas and the coast between towns are patchy or dead. Data is slow by North American or European standards, and video calls are unreliable even in Havana.

The bigger issue is the power grid. When it collapses, mobile data and Wi-Fi go down with it, sometimes for hours or days. That is not a reason to skip the SIM, but it is a reason not to depend on it: keep paper copies of key addresses, agree meeting points in advance, and carry enough cash that you never need an app to pay.

Networks are also filtered. Some sites and services do not load normally, which is why a VPN matters. If a page fails, try the VPN before assuming the site is down.

ETECSA runs public Wi-Fi hotspots in parks, squares and some public buildings, and many hotels and casas have their own networks. Hotspot access is usually bought as a scratch card or an account with a username and password, and cards can sell out in busy areas. Hotel Wi-Fi is often included in the room rate but is slowest in the evening when everyone is online.

Use hotspots for the tasks that need a real connection: uploading photos, checking in for a flight, sending a long message home. Do them early in the day if you can. Public networks are not private, so avoid banking on them unless your VPN is running.

Cuba uses the same GSM and 3G/4G bands as most of Europe and the Americas, so a modern unlocked phone generally works. Older CDMA-only handsets do not. Country code is +53, and Cuban mobile numbers are reached normally once you have a local SIM.

The apps that matter are the ones that work offline or over weak data: an offline map, a translation app with Spanish downloaded, WhatsApp for casas and drivers, and a VPN. Check that any exchange-rate app you plan to use loads without a VPN, and keep a small calculator for the informal rate.

If you are travelling with a partner or group, one local SIM plus WhatsApp is usually enough for the whole party. Two SIMs only help if you split up.

Treat every number here as a 2026 estimate. Tourist SIMs and data bundles are priced in convertible currency and cost more than local plans; a small bundle for messaging and maps is the usual choice, with top-ups as you go. Hotspot cards are sold in small denominations, and hotel Wi-Fi is either included or charged per device per day.

The hidden cost is roaming. Some foreign carriers do not offer a Cuba package at all, and pay-as-you-go rates can be extreme. Ask your carrier for a written Cuba rate before you fly, and if there is no package, plan on buying locally instead.

Keep your passport with you when you buy or register a SIM, and keep the SIM packaging until you leave. If your phone is your camera and your map, carry a power bank: charging points are limited on long drives, and a dead phone in a town with no working hotspot is a real problem.

Do not plan on booking transport or accommodation through apps at short notice. Arrange the next leg before you lose signal, and write down the address and phone number of where you are going. For the wider trip, see plan your trip to Cuba and cost of travel in cuba.

If you have a medical condition or take regular medication, carry your own supply and a copy of your prescription; see Cuba health and vaccines. For travel dates, check Cuba best time to visit and cuba public holidays, since holidays affect office hours for SIM registration and top-ups.
