Cubacel, at this point, is the only telecom provider in Cuba. It it owned by ETECSA, a government owned telecommunications service provider. ETECSA provides telephone, internet and wireless services. Telecommunication works well on the island, but the internet and wireless is not as developed.
Travelling to Cuba,tourists need to keep in mind, using the internet it is rather slow. The same applies for Wi-Fi spots. There are only a few hotspots on the island and the connection is rather slow too.
Receiving or making calls in Cuba, for locals as well as tourists, costs 0,10 CUC or even 0,35 CUC per minute, depending on whether it is off or during peak hours.
If you still need to make calls in Cuba, renting a Cubacel SIM card is a cheaper option as you do not have to pay for roaming. Even though foreigners are not allowed to buy their own SIM card, they are able to rent one. There are various ETECSA offices in Cuba, either at the airport or in the city where SIM cards are rented to tourists for 3 CUC per day.
You can top up Cuban SIM cards for friends or family here, starting from 10 CUC.
