Common Questions

The details worth knowing about your Cuba eSIM

Coverage exists in Havana and Varadero as both are major towns. On the highway between them, you may fall back to 3G or lose data service entirely, since Cubacel concentrates LTE in provincial capitals and urban areas, not along most roads.

It depends. Cubacel uses 4G on bands 1 and 3. Without band 1 you may still connect on band 3 in areas where that band is deployed, but coverage will be less reliable. Some locations might only broadcast band 1, leaving you on 3G or no data.

Cubacel's network does not extend onto the US naval base at Guantánamo Bay. While on the base, your eSIM may roam onto a US carrier depending on agreements. Off the base in Cuban territory, Cubacel coverage is limited to the town of Guantánamo.

Based on available information, Cubacel does not block or throttle WhatsApp or similar messaging apps. Normal data speeds apply on their 4G bands in covered areas. No specific restrictions are reported for these services on Cubacel's network.

This eSIM is designed for Cuba only. If your phone connects to a Mexican network while still in range of Cancún, data usage would follow the eSIM's roaming terms. For certainty, disable data until you are sure you are on Cubacel's network inside Cuba.
