eSIM for Cuba — How to get internet in Cuba without problems

Traveling to Cuba is an incredible experience, but arriving without data can ruin the first moments: no Google Maps to leave the airport, no way to look for the hotel, no way to contact whoever is waiting for you. The solution is simple and has been the standard among experienced travelers for years: an eSIM for Cuba.

In this guide, we tell you everything you need to know before traveling to Cuba: what coverage you can expect in Havana, Trinidad, and Varadero, how many GB you really need, how to activate the eSIM, and the best connectivity tips from those who have already traveled there.

Spoiler: with PuraSim, you have local data from the moment your plane lands, with no contracts, no physical SIM, and no bill surprises.

Why do you need an eSIM to travel to Cuba?

International roaming from European and Latin American operators can cost you between 10 and 30 euros or dollars per day in Cuba. A local eSIM gives you data at a local price, without absurd daily limits and with 4G or 5G speeds where the network allows it.

The difference between going with roaming and with a PuraSim eSIM is brutal:

• Traditional roaming: fixed daily rate even if you barely use data, speed often limited to 3G, surprise bills upon return.
• PuraSim eSIM for Cuba: you only pay for what you contract, full local data at maximum available speed, activation in 5 minutes from anywhere.

In addition, with an eSIM, you can keep your original phone number active to receive calls and SMS, as the eSIM operates in a separate virtual slot. You don't have to choose between local connectivity and your usual number.

For Cuba, where Cuba has a network controlled by ETECSA; many international eSIMs work with variable roaming coverage, having stable data is especially important. Coverage in Havana, Trinidad, and Varadero is generally good, but there are areas where without a well-configured local eSIM you would be blind.

Data coverage in Cuba: what you can expect

Coverage in Cuba varies considerably by area. In the main urban and tourist areas (Havana, Trinidad, and Varadero) you will find 4G and in some cases 5G networks. The experience is comparable to what you would have at home.

However, as in any destination, there are areas where the signal is more limited:

• Main cities: stable 4G/5G, perfect for streaming, browsing, and video calls.
• Rural and nature areas: coverage may drop to 3G or even lose signal in remote areas.
• Transport: trains, ferries, and intercity buses have variable coverage; generally good in cities.

Key tip: Cuba has a network controlled by ETECSA; many international eSIMs work with variable roaming coverage

To maximize coverage in Cuba, PuraSim uses the local networks with the best available infrastructure through local roaming agreements. This means that your eSIM automatically connects to the network with the best signal at all times.

How many GB do you need for traveling to Cuba?

This is the million-dollar question. The short answer: 3-5 GB (limited network). The long answer depends on how you use your mobile phone during the trip.

Here is a guide to actual consumption by type of daily use:

• Basic use (maps, messages, occasional queries): 300-500 MB/day
• Moderate use (social media, photos, continuous browsing): 800 MB-1.5 GB/day
• Intensive use (remote work, streaming, video calls): 2-4 GB/day

For a trip to Cuba of the usual duration, our recommendation is to contract 3-5 GB (limited network). This is sufficient for most travelers with normal use: Google Maps constantly running, Instagram, WhatsApp, and some occasional searches.

If you are going to work remotely or plan to make frequent video calls, upgrade to the next plan immediately. PuraSim plans allow you to top up data if you run out, so it's not a problem if you fall short: you won't suddenly lose coverage.

PuraSim offers specific plans for Cuba with different data and duration options. Check out the complete collection in our plans for Cuba.

How to activate your eSIM for Cuba step-by-step

Activating a PuraSim eSIM is as simple as scanning a QR code. There is no need to go to a store, no need to wait for any delivery. The complete process takes less than 5 minutes:

1. Purchase your plan on purasim.com for Cuba. You will receive an email with the QR code.
2. Install the eSIM: go to Settings → Mobile Data → Add Data Plan (on iPhone) or Settings → Connections → SIM Manager (on Android).
3. Scan the QR code or manually enter the activation details.
4. Configure mobile data: make sure to select the PuraSim eSIM as the default data line.
5. Activate data roaming in the PuraSim eSIM settings (necessary for it to work on local networks).

You can install the eSIM before leaving home and configure it to activate automatically when you arrive in Cuba, or activate it manually when you land.

Important: verify that your phone is compatible with eSIM before purchasing. Most iPhones from XS, Samsung Galaxy from S20, and Google Pixel from 3 are compatible. Check the complete list on purasim.com.

Local connectivity tips for Cuba

Beyond getting the right eSIM, there are some tricks that make a difference to stay connected throughout your trip to Cuba:

• Download offline maps before leaving. Google Maps and Maps.me allow you to download maps of all of Cuba or specific cities. This way you can navigate without spending data when you are in areas with weak signal.
• Use airplane mode strategically. On long flights, trains, or ferries, activating airplane mode preserves battery and data. Connect to available WiFi if there is any.
• WhatsApp and Telegram over data. Calls via these apps consume much less than an international call. Configure them for high-quality calls only when you are on WiFi.
• Share connection carefully. Hotspot consumes data quickly, especially if there are other devices connected (laptop, tablet). Use it only when necessary.

And the most important tip: Cuba has a network controlled by ETECSA; many international eSIMs work with variable roaming coverage

With these tricks and a good PuraSim data plan, your trip to Cuba will have the connectivity you need without unnecessary expenses.
