Cuba connectivity: SIM cards, eSIMs, internet and Wi-Fi

The main ways to stay connected in Cuba are a Cubacel tourist SIM, a compatible travel eSIM, international roaming or Wi-Fi. Mobile data is available through Cuba’s cellular network, while hotels, airports and public Wi-Fi zones provide additional internet access. However, coverage, speeds and costs can vary, so arranging your preferred option before travelling can make arrival easier.

ETECSA operates Cuba’s telecommunications infrastructure, while Cubacel provides mobile services. Visitors who need regular internet access will usually find a tourist SIM or suitable travel eSIM more convenient than relying entirely on Wi-Fi. Alternatively, international roaming may suit travellers who only need occasional connectivity and have an appropriate roaming package.

This guide explains SIM cards, eSIMs, mobile networks, Wi-Fi, roaming and phone compatibility in Cuba. It also covers the +53 country code, international calling, emergency telephone numbers and practical ways to prepare your phone before travelling.

What is the best way to stay connected in Cuba?

For most travellers who need regular internet access, a Cubacel tourist SIM or compatible travel eSIM will usually provide more flexibility than relying entirely on Wi-Fi. However, the best choice depends on your phone, trip length, data needs and whether you need a Cuban telephone number.

A travel eSIM may provide the simplest option if your phone supports eSIM technology and a suitable provider covers Cuba. You can often install an eSIM before departure, which means you do not need to replace your usual physical SIM. Nevertheless, check the activation requirements and whether the plan includes only data or also supports calls and texts.

In contrast, Cubacel Tur may suit travellers who want a Cuban mobile number alongside calls, texts and mobile data. International roaming requires less preparation because you can keep your existing SIM and telephone number, although charges may be considerably higher.

Wi-Fi alone can work for travellers who need only occasional internet access. However, it provides less flexibility when you need maps, messages or travel information while moving between locations.

SIM cards for visitors to Cuba

Visitors who want a Cuban mobile number and mobile data can use the Cubacel Tur tourist service. It provides a temporary Cuban mobile line with data, calls and text messages.

Different Cubacel Tur packages and validity periods may be available. However, allowances, prices and purchasing arrangements can change. Check the current Cubacel Tur options before paying rather than relying on an older package description found online.

Where can tourists get a SIM card in Cuba?

Cubacel Tur can be arranged before arrival and collected at participating locations in Cuba. Collection points include ETECSA commercial offices and facilities at international airports, although available services can vary by airport and terminal.

You may need to provide your passport when collecting or registering a tourist SIM. Therefore, keep your travel document accessible rather than packing it in checked luggage.

What do I need to use a Cuban SIM?

• a compatible mobile phone;
• an unlocked handset;
• your passport or other required identification; and
• a suitable Cubacel Tur package.

If your phone uses only eSIM technology and has no physical SIM slot, check your alternatives before buying a local physical SIM.

Should I arrange a Cuba SIM before travelling?

Arranging your connectivity before departure can make arrival easier, particularly if you need mobile data for directions or contacting accommodation. Nevertheless, check the collection instructions carefully because arranging a Cuban tourist SIM online does not necessarily mean that the service becomes active on your phone before you reach Cuba.

Can you use an eSIM in Cuba?

Yes, some international travel eSIM providers offer data services that cover Cuba. These products generally connect through a local mobile network using a roaming arrangement rather than providing a standard Cuban mobile subscription.

An eSIM can be particularly convenient if your phone supports the technology because you may be able to install the plan before departure while keeping your normal physical SIM in your phone. However, do not activate a plan prematurely if its validity period starts immediately after activation.

Availability, allowances and connection arrangements vary between providers. Therefore, confirm that the eSIM explicitly covers Cuba, supports your device and provides enough data for your trip before purchasing it.

Does a Cuba travel eSIM include calls and texts?

Not necessarily. Many travel eSIM products provide mobile data without a conventional Cuban telephone number, calls or text messages. You can still use internet-based messaging and calling services with a suitable data connection, but check the individual plan if conventional calls or texts matter to you.

Will my phone work in Cuba?

Your phone may work in Cuba if it supports the mobile frequencies used locally and is compatible with your chosen SIM, eSIM or roaming service. If you want to insert a Cuban physical SIM, your handset must also be network-unlocked.

Cuba’s tourism authorities currently identify 900 MHz band 8 for 3G and 1800 MHz band 3 for 4G. Consequently, check your handset specifications if you are unsure whether your phone supports the required network bands.

Before travelling, check:

• whether your phone is network-unlocked;
• whether it supports the mobile bands used in Cuba;
• whether it accepts a physical SIM, eSIM or both;
• whether your home mobile network offers roaming in Cuba; and
• whether any travel eSIM you plan to buy supports your device.

Additionally, check whether your phone uses a physical SIM slot if you intend to use Cubacel Tur. Some newer handsets sold in certain markets rely entirely on eSIM technology.

Mobile networks and coverage in Cuba

ETECSA operates Cuba’s national telecommunications infrastructure, including the Cubacel mobile service. Unlike destinations with several competing mobile networks, Cuba does not offer visitors a large choice of domestic mobile operators.

Mobile coverage extends across populated areas and major tourist destinations, although connection quality can vary. Consequently, do not assume that the mobile data experience you have in Havana or a major resort will continue in rural or more remote areas.

Mobile internet and data in Cuba

Mobile internet is available through Cuba’s cellular network, including 3G and 4G services in supported areas. However, speed and reliability can vary according to your location, network demand and device.

For that reason, avoid relying on continuous high-speed internet for essential travel arrangements. Download important information before departure and keep offline copies of anything you may need urgently.

This preparation becomes particularly useful when travelling outside Havana, major cities and established resort areas, where connections may become weaker or less consistent.

Wi-Fi and internet access in Cuba

Wi-Fi is available in Cuba at locations including hotels, airports and designated public access areas. ETECSA also operates public Wi-Fi zones across the country.

Access arrangements differ by location. Some connections may form part of your accommodation package, while other services may require a Nauta account or temporary navigation card.

How do ETECSA Wi-Fi zones work?

ETECSA public Wi-Fi zones allow users to connect through designated wireless access points. Temporary Nauta access can be purchased for occasional internet use, with login details used to authenticate the connection.

You can find Wi-Fi zones in locations such as parks, squares and tourist areas. Nevertheless, mobile data will usually provide more flexibility if you need frequent internet access while travelling around Cuba.

Do Cuban hotels have Wi-Fi?

Many hotels provide internet access, particularly properties serving international visitors. Cuba’s official tourism information states that customers at four- and five-star hotels can access Wi-Fi as part of the services offered.

However, Wi-Fi availability does not guarantee a fast or reliable connection. Ask your accommodation about its current service if you need internet access for work, video calls or another data-intensive activity.

Is there Wi-Fi at Cuban airports?

Cuba’s tourism authorities state that travellers can receive a limited period of free Wi-Fi at international airports. Access arrangements can change, so treat airport Wi-Fi as a useful arrival service rather than your main connectivity plan.

International roaming in Cuba

Your existing mobile provider may offer international roaming in Cuba if it has an appropriate agreement with the Cuban mobile network. However, roaming availability and charges vary considerably between providers.

Before travelling, check:

• whether your network supports roaming in Cuba;
• the price of mobile data;
• incoming and outgoing call charges;
• text message charges;
• whether your roaming pass specifically includes Cuba; and
• any daily or monthly data limits.

In particular, do not assume that a Caribbean, North American or worldwide roaming bundle automatically includes Cuba. Mobile providers define their geographical roaming zones differently.

To prevent unexpected charges, keep data roaming disabled until you have confirmed your tariff. You can then decide whether roaming, a Cuban SIM or an eSIM provides better value for your trip.

Using WhatsApp and internet calling apps in Cuba

Messaging and internet calling apps can reduce your need for conventional international calls when you have a suitable internet connection. For example, travellers can use internet-based services to contact accommodation, friends or family.

The performance of voice and video calls depends on connection quality. Therefore, a text message may work when a video call struggles on a slower or unstable network.

If a particular communication app is essential to your trip, install it and complete any account verification before travelling. This avoids needing to receive an authentication message when you may not have reliable access to your usual mobile number.

What to download before travelling to Cuba

Even if you plan to buy a SIM or eSIM, prepare for periods without reliable internet access. A few downloads before departure can make travelling considerably easier.

Consider saving:

• offline maps for the places you plan to visit;
• flight, bus and accommodation confirmations;
• your travel insurance policy and emergency contact details;
• copies of important travel documents;
• addresses for your accommodation;
• airline and transport information;
• translation resources that work offline; and
• important telephone numbers.

Additionally, take screenshots of information that you may need immediately after landing. Do not rely on being able to retrieve every booking from your email or a cloud service when you arrive.

Cuba country code and phone numbers

The international calling code for Cuba is +53. Use +53 before a Cuban telephone number when calling from another country or saving a Cuban number in international format.

Saving numbers with the +53 prefix can make them easier to use when you change SIM cards or travel between countries.

Cuban mobile numbers

Cuban mobile numbers use the national numbering system and should be stored with +53 when you want an internationally formatted contact.

Use the following format: +53 + Cuban mobile number

Do not add an additional international access code when your phone accepts the + symbol.

Cuban landline area codes

Landline numbers use geographic codes associated with different parts of Cuba. For example, Havana uses the area code 7.

When calling a Cuban landline internationally, use: +53 + area code + local number

How to call Cuba from another country

To call Cuba internationally, use your country’s international access method followed by Cuba’s +53 country code and the Cuban telephone number.

On a mobile phone, the simplest format is usually: +53 + Cuban telephone number

Calling a Cuban mobile

Enter +53 followed by the complete Cuban mobile number.

Calling a Cuban landline

Enter +53, followed by the relevant geographic area code and local telephone number.

International calling charges depend on your telephone provider. Consequently, check the rate before making a long call.

How to call another country from Cuba

Cuba uses 00 as the international dialling prefix for conventional international calls.

The general format is:

00 + country code + area code where required + telephone number

Alternatively, a mobile phone may allow you to use the + symbol followed by the destination’s country code and telephone number.

International calls can cost considerably more than internet-based communication. Therefore, compare conventional calling charges with messaging or internet calling services when you have a suitable data connection.

Emergency telephone numbers in Cuba

Save Cuba’s main emergency numbers before travelling rather than relying on internet access during an emergency.

Cuba emergency numbers

These short emergency numbers are intended for use within Cuba. In addition, keep your travel insurer’s emergency assistance number and your accommodation contact details somewhere you can access offline.

Using your phone and public Wi-Fi securely in Cuba

Public Wi-Fi can be convenient, but treat open or shared networks with appropriate caution. Avoid sending sensitive information over an unsecured connection where possible.

Before travelling:

• install operating system and app updates;
• enable a screen lock and device tracking;
• back up important photographs and documents;
• use two-factor authentication where appropriate;
• record your phone’s IMEI number;
• keep your usual SIM somewhere secure if you replace it; and
• know how to contact your mobile provider if your phone is lost or stolen.

Additionally, avoid leaving your phone unattended while charging in public places. If you lose your device, contact your mobile provider promptly and change important account passwords if necessary.
