The following instructions provide examples based on Telus service. Substitute the name
of your mobile network operator (MNO). Key values and parameters are bolded for
emphasis in the examples.
For detailed information about the AT commands used, refer to WP8548/WP75xx/
WP76xx/WP77xx AT Command Reference (document number 4118047) available at
source.sierrawireless.com.
To use the FX30S as a USB modem:
1. Ensure that your computer is set up to issue AT commands to the FX30S. (See Setup
for Windows on page 34.)
2. Connect the radio to the network:
a. If you have not already done so, install the SIM card. (See Step 1—Insert the SIM
Card and Optional IoT Expansion Card on page 12.)
b. Set the MNO’s APN using the AT+CGDCONT command. (Most MNOs use Profile
number 1. To confirm, check with your MNO.)
AT+CGDCONT=1,"IPV4V6","isp.telus.com"
c. Check that the profile is correctly set:
AT+CGDCONT?
+CGDCONT: 1,"IPV4V6","isp.telus.com","0.0.0.0",0,0
d. Check that the radio is attached and registered on the network.
