Note for LE910-NA1 Modem: AT&T / Verizon firmware support
The LE910-NA1 modem supports both AT&T and Verizon firmware.
The firmware used by the modem needs to be set the first time the modem is used. Once the modem
firmware has been set, the same firmware will load on each modem reset.
A firmware switch between the two modem firmware versions can be performed during operation.
With dual SIM usage on the ReliaGATE 10-12 it is possible to load both an AT&T and a Verizon SIM into
the MicroSIM card holders, and then switch between Verizon and AT&T firmware and their respective SIM
cards to provided coverage on either network. Due to the firmware switch, simultaneous operation is not
possible.
AT&T / Verizon firmware selection is performed using an AT command. This loads the respective AT&T /
Verizon firmware, resets the modem, and then re-enumerates the device on the bus.
NOTE: Allow 20 seconds from the execution of the command before sending further AT commands to
allow the device to be re-enumerates on the USB bus.
