1. At least one computer-readable storage medium, excluding transitory signals and carrying instructions to reduce cellular telecommunication network traffic, which, when executed by at least one data processor of a system, cause the system to:
obtain an international mobile subscriber identity (IMSI) range associated with multiple mobile devices operating on a private cellular telecommunication network providing connectivity to the multiple mobile devices within a limited geographical range;
obtain a) a subscription profile associated with a mobile device among the multiple mobile devices operating on the private cellular telecommunication network, and b) authentication credentials associated with the mobile device operating on the private cellular telecommunication network,
wherein the subscription profile indicates a service authorized to be provided to the mobile device, and
wherein the authentication credentials are verified prior to providing the service to the mobile device;
store the IMSI range, a first subscription profile, and the authentication credentials in a first database associated with a first public cellular telecommunication network,
wherein the first subscription profile is based on the subscription profile, and
wherein the first public cellular telecommunication network provides connectivity to the mobile device when the mobile device is outside the limited geographical range;
receive a request from the mobile device to connect to the first public cellular telecommunication network,
wherein the mobile device is outside the limited geographical range;
reduce the cellular telecommunication network traffic by:
obviating the need to initially connect to the private cellular telecommunications network by authenticating the mobile device using the authentication credentials stored in the first database of the first public cellular telecommunications network without requesting authentication from the private cellular telecommunication network; and
determining that the service is authorized to be provided to the mobile device based on the first subscription profile stored in the first database without requesting the subscription profile from the private cellular telecommunication network; and
upon authenticating the mobile device and determining that the service is authorized to be provided to the mobile device, provide the service to the mobile device.
