Wireless Communications Methods and Devices Selecting Configurations from Multiple Configurations Stored in Nonvolatile Memory

摘要

A wireless communications device obtains a configuration identifier and selects a wireless communications configuration from among a plurality of wireless communications configurations stored in a non-volatile memory of the wireless communications device based on the configuration identifier. The wireless communications device applies the selected wireless communications configuration to configure the device for use with a network. Respective ones of the plurality of wireless communications configurations may correspond to respective networks; and the configuration identifier may include a network identifier obtained, for example, from a subscriber identity module (SIM) engaged with the wireless communications device.
