Skype

Yes, you can use Movistar mobile broadband in Cuba to make calls on Skype, provided you have a good internet connection. However, internet access in Cuba can be limited and may not be reliable. A cheaper alternative for calling home is to use a local calling card or VoIP service, which often offers better rates than traditional mobile or international calls.
