1. A method, comprising:
upon a power-on of a user device that does not include a subscriber identity module (SIM) card, detecting, by the user device, at least one wireless network at a current location of the user device; determining, by the user device, that a default device profile stored on the user device does not correspond to the detected wireless network at the current location of the user device; obtaining a device profile comprising a SIM profile and a modem profile corresponding to a primary wireless network at the current location of the user device, wherein the primary wireless network uses a standard that specifies the use of SIM cards, and wherein the SIM profile comprises an international mobile subscriber identity (IMSI) comprising a mobile country code (MCC) of the primary wireless network, a mobile network code (MNC) of the primary wireless network and a mobile station identification number (MSIN) associated with the primary wireless network and acts as a substitute for the SIM card by associating the user device with the primary wireless network and providing additional functionality conventionally provided by the SIM card, and wherein the modem profile comprises connection parameters of the primary wireless network, the connection parameters comprising wireless protocol configuration data; responsive to detecting that the default device profile does not correspond to the detected wireless network, reprogramming a modem of the user device using the device profile comprising the SIM profile and the modem profile corresponding to the primary wireless network at the current location of the user device; power cycling the modem of the user device after reprogramming the modem to initiate a network connection using the device profile; and establishing the network connection using the device profile comprising the SIM profile and the modem profile corresponding to the primary wireless network at the current location of the user device responsive to the power cycling. |
