SIM Cards and Airtime for satellite phones
You'll need a SIM card for the operation of most telephones and terminals. Exceptions are some Iridium modems that only support the Iridium SBD service and that are identified by device number (IMEI). For prepaid and postpaid contracts different SIM cards are required. Prepaid credits for Iridium and Inmarsat are purchased as virtual credits and not physical shipping goods. Thuraya prepaid credit is the exception and is purchased via physical PIN codes. SIM cards only work in devices designed for the respective satellite network. Prepaid and postpaid contracts are tied to the SIM card merchant. Again, the exception: Thuraya prepaid is available at every reseller.
