1. A computer-implemented method for implementing network access technology control, the computer-implemented method comprising:
responsive to detecting an event associated with a mobile computing device, accessing location information associated with a location of the mobile computing device;
accessing a configuration table stored in association with a subscriber identity module (SIM) of the mobile computing device, wherein the configuration table indicates permissible network access technologies for the mobile computing device to utilize at each of one or more locations;
determining, based at least in part on the configuration table, on network access technology data provided by a network and on the location information, that a current network access technology of the mobile computing device is an impermissible network access technology for the mobile computing device in the location;
generating, by the SIM and based at least in part on determining that the current network access technology is the impermissible network access technology for the mobile computing device in the location, an error notification configured to prohibit the mobile computing device from connecting to the network via the current network access technology; and
sending, from the SIM to another component of the mobile computing device, the error notification, the error notification including an indication of at least one alternate network access technology.
