Abstract
Methods, devices and systems enable the dynamic updating of home public land mobile network (HPLMN) information stored on a subscriber identification module (SIM) to avoid a roaming indication, without requiring any modifications to the mobile device modem, SIM application programming interface (API), the modem software, or the mobile device operating system. A mobile device may scan available public land mobile networks (PLMNs) to identify a participating PLMN to which the mobile device may connect, and receive network values having a mobile country code (MCC) value and a mobile network code (MNC) value from the identified PLMN. The mobile device may overwrite an existing HPLMN value and/or one or more IMSI values on the SIM with the receive network values.
