Adapting subscriber identity module (SIM) card

A method of initiating a mobile communication device, comprising:

• requesting, by an initiation application executing on a subscriber identity module (SIM) card, an international mobile equipment identity (IMEI) from the mobile communication device, wherein the SIM card stores a plurality of profile components for different wireless protocols, different device brands, and different device models;
• attempting to look up a type allocation code (TAC) of the mobile communication device based on the IMEI in a TAC table of the SIM card;
• in response to finding a TAC associated with the IMEI in the TAC table, attempting to look up a profile identity based on the TAC in a profile table of the SIM card;
• in response to a power-on event of the mobile communication device and in response to failing to find the TAC associated with the IMEI in the TAC table or failing to find a profile identity associated with the TAC in the profile table, presenting a dialer keypad interface on a display screen of the mobile communication device;
• transmitting dialed digits from a dialer application executing on the mobile communication device to the SIM card connected to the mobile communication device;
• based on the dialed digits, building, by the initiation application, a SIM profile having a subset of profile components selected from the plurality of profile components stored in the SIM card, where the SIM profile comprises an international mobile subscriber identity (IMSI), a public land mobile network (PLMN) file that defines roaming behavior, and mobile network authentication keys;
• sending a refresh proactive command by the initiation application to a radio transceiver of the mobile communication device;
• and
• sending at least some of the contents of the SIM profile to the radio transceiver by the initiation application.

A subscriber identity module (SIM) card, comprising:

• a processor;
• a non-transitory memory;
• a plurality of profile components for different wireless protocols, different device brands, and different device models, where the plurality of components comprise the components of a USIM, the components of a CSIM, and the components of an ISIM;
• an initiation application stored in the non-transitory memory that, when executed by the processor;
• in response to a power-on event of a mobile communication device into which the SIM card is installed, requests and receives an international mobile equipment identity (IMEI) from the mobile communication device;
• looks up a type allocation code (TAC) in a table stored in the non-transitory memory based on the IMEI to determine an identity of a brand and model of the mobile communication device;
• looks up a profile identity in a table of profile identities stored in the non-transitory memory based on the looked-up TAC;
• based on the looked-up profile identity, builds a SIM profile having a subset of profile components selected from the plurality of profile components stored in the SIM, where the SIM profile is associated with the looked-up profile identity and comprises an international mobile subscriber identity (IMSI), a public land mobile network (PLMN) file that defines roaming behavior, and mobile network authentication keys;
• sends a refresh proactive command by the initiation application to a radio transceiver of the mobile communication device;
• and
• sends at least some of the contents of the SIM profile to the radio transceiver.
