A subscriber identity module (SIM) card. The SIM card comprises a processor and a non-transitory memory that stores an initiation application and a plurality of profile components, where the plurality of components comprise the components of a USIM, the components of a CSIM, and the components of an ISIM. When executed by the processor, the initiation application looks up a profile identity in a table of profile identities stored in the non-transitory memory based on an identity of a brand and model of a mobile communication device with which the SIM card is associated, builds a SIM profile associated with the looked-up profile identity from the plurality of profile components, where the SIM profile comprises an international mobile subscriber identity (IMSI), a file that defines roaming behavior, and mobile network authentication keys, and sends at least some of the contents of the SIM profile to the radio transceiver.
