Problems solved by technology

However, despite recent improvements in cellular and mobile communications technology, mobile device modems are often still tied to a specific cellular service provider (e.g., Vodophone, etc.) and / or networks, and communicating through a different service provider's network (which is often referred to as "roaming") is often more expensive than communicating through the mobile device's home network
These factors tend to limit mobile device users' access to content, data, and communications when the mobile device is located outside the geographic range of its home service provider's network

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.

Description

Background technique [0001] Cellular and mobile communication technologies have seen explosive growth over the past few years. Cellular service providers now offer a wide variety of features and services, and wireless dongles and embedded wireless modem cards enable users to use their mobile electronic devices (e.g., tablet computers, laptops, etc.) network to access wireless Internet Protocol (IP) and data services. Thus mobile device users now expect to be able to access IP and data services from their mobile devices anywhere in the world. However, despite recent improvements in cellular and mobile communications technology, mobile device modems are often still tied to a specific cellular service provider (e.g., Vodophone, etc.) and / or networks, and communicating through a different service provider's network (which is often referred to as "roaming") is often more expensive than communicating through the mobile device's home network. These factors tend to limit a mobil...
