Mobile phones and SIM cards
Sim cards for mobile phones are currently available for € 1. With that amount of credit, and if you intend to remain in Montenegro for an extended period of time, making local phone calls will be well worth the cost. In order to activate a prepaid number at a local operator’s shop as of 2011, you must fill out a brief form and present ID or a passport.
