CONFIGURING AN ELECTRONIC DEVICE FOR WIRELESS COMMUNICATIONS

摘要

In an implementation, an electronic device may obtain a configuration file from a device provider. The configuration file may include settings of a number of communications providers for communicating over a wireless wide area network. A subscriber identification module (SIM) card may include information, such as a communications provider identifier, that is utilized to determine the settings for a modem of the electronic device. Configuring the modem of the electronic device according to the settings may cause the modem to communicate over the wireless wide area network according to specifications of a particular communications provider of the plurality of communications providers.

主权项

1. A portable electronic device comprising:
one or more processors; a subscriber identification module (SIM) card including an identifier of a first communications provider; a modem to communicate via a wireless wide area network, the modem including a non-volatile memory; one or more computer-readable storage media storing:
a configuration file including first settings to configure the modem to communicate via the wireless wide area network according to a first specification of the first communications provider and second settings to configure the modem to communicate via the wireless wide area network according to a second specification of a second communications provider, at least one of the second settings being different from at least one of the first settings; andinstructions executable by the one or more processors to perform operations comprising:
determining that a version of the configuration file matches a current version of the configuration file;determining that the SIM card has been inserted into the portable electronic device;determining, based at least in part on the identifier of the first communications provider, that the modem is to communicate via the wireless wide area network according to the first specification of the first communications provider;storing the first settings in the non-volatile memory of the modem; andconfiguring the modem to communicate via the wireless wide area network according to the first settings.
