METHOD FOR ENABLING OPERATION OF A WIRELESS MODEM
The present invention provides a method for enabling operation of a wireless modem configured for operation with a Subscriber Identity Module (SIM). The method comprises determining a personal identification number (PIN) based at least in part on a predetermined network domain; configuring the SIM to release wireless network access data only upon providing the PIN; determining a network domain of a user session on a user device, the user device operatively connected to the wireless modem; determining a SIM-unlock code based at least in part on the network domain associated with the user device; providing the SIM-unlock code to the SIM; and comparing the SIM-unlock code to the PIN; whereby wireless network access is enabled only if at least the network domain associated with a user device corresponds with the predetermined network domain.
