Abstract
Connection settings used by a mobile device to connect to a packet data network, e.g. the internet, are stored in a subscriber identity module (SIM) card. This enables connection settings to be pre-loaded on a SIM card, allowing a mobile device to immediately connect to the internet without manual configuration. The mobile device's connection settings may also be updated by a mobile network operator via an over the air profile update. For example, the operator may supply a device with connection settings the first time it connects to the network. Connection settings may be stored in one or more files within the SIM profile, and may be updated via a remote file management operation. Embedded-SIM (eSIM) profiles may also store connection settings in profile metadata, which may be updated via a metadata update operation.
