A rule server detects a condition pertaining to a switch of a user device to a preferred wireless carrier, and sends a message to the user device indicating a switch to the preferred wireless carrier.

Dynamic carrier switching

A user device determines a current subscriber identity module (SIM) profile, identifies a modem profile that corresponds to the current SIM profile, and updates a non-volatile memory of a modem with the identified modem profile.

Single version of a user device modem for use with different wireless carriers

A user device obtains a device profile corresponding to a primary wireless network at a current location of the user device, reprograms a modem of the user device using the device profile corresponding to the primary wireless network at the current location of the user device, and establishes a network connection using the device profile corresponding to the primary wireless network at the current location of the user device.

World SIM

An idle universal serial bus ('USB') is placed into a low power mode. During low power mode, peripherals attached to the USB bus may also enter a low power mode. While in this low power mode, USB attached peripherals may retain some functionality. For example, a USB attached modem may remain connected, allowing rapid resumption of communications upon awakening.
