All FSMTCeLL customers may use their mobile to dial directly to any FSM state or to any international destination. To place a long distance call to a FSM state, you may either simply dial the desired telephone number of your FSM state destination or dial 1 + telephone number of the destination party (can be both to mobile number or fixed line). To place an international call, dial 011, country code, city code and telephone number of the destination party.
In order to access the FSMTC mobile network, you must have a GSM mobile phone and a SIM card. When you call a fixed or mobile phone, a base station, fitted with a transmitter/receiver/antennae system, receives and transmits your message. This base station is connected to the telephone exchange, whose main function is to maintain the call when you leave one cell and enter another, and also collects the necessary data for billing and accounting.
