Configuring Device Firmware for Your Cellular Network

Before connecting to a cellular network, you need to configure the device for that cellular network. This step is
required only the first time you use the device and if you change cellular carrier.
Important: Configure the device for Cat M1 use only. Use AT#WS46=0 to ensure the device is in Cat M1 mode.
Failure to set the device for Cat M1 use only may delay network registration times and cause the device to be
used in a manner for which it was not approved.

Carrier Values

0 AT&T/other networks
1 Verizon
2 ROW (Other global).
3 Australia

Checking the Cellular Network

To check the device's current cellular network:
AT#FWSWITCH?

Setting the Cellular Network

To set the cellular network, issue the following:
AT#FWSWITCH=<carrier value>,1,1,
Where carrier value is the 1, 2, 3, or 4 depending on your network.
The device automatically reboots twice. After the second reboot, the device is ready for configuring the data
connection.
Note: For the Link status (LS) LED to function, you must issue the command AT#GPIO=1,0,2 any time you use
the firmware switch command (AT#FWSWITCH=0 or AT#FWSWITCH=1).
For more information on AT#FWSWITCH, refer to the AT command reference guide.
