how much is a sim card in cuba
Cubatel's SIM cards come with pre-paid minutes in amounts of 10, 20, or 40 Cuban convertible pesos (CUC$) (US$10, $20, or $40), plus a daily rental fee for the SIM card of CUC$3 (US$3). The per-minute call charges and texting fees for renting a mobile phone (as listed below) also apply to renting a SIM card.
Cuba's only mobile phone operator, Cubacel, provides the service of renting SIM cards for tourists to use in their mobile phones, thus providing them with a local mobile phone number while they are in Cuba. The cost of renting a SIM card is 3CUC per day, and to rent a handset costs 6CUC per day. There is no official system for tourists to buy a SIM card in Cuba. If you are using your own handset, it needs to work on the 900MHz frequency band for it to work in Cuba.
