LTE M1 coverage

End-of-Life Product Cellular IoT HAT
1

Trying to configure IOT hat as LTE M1 with an active Twilio SIM. When running configuration and test SMS, I dont see any success. What lacks is transparency is coverage at my current location. If I’m to use in a product, I’d want to be able to tell if theres coverage at whichever location I’m deploying it to.

Hi @ivan.zhidov,

For this, use the AT+QNWINFO command.
“The command indicates network information such as the access technology selected, the operator, and
the band selected.”

This command added to the configureCATM1.py file. Thanks for your enquiry!

I got it to work, still a bit unstable on staying connected but I can see network MCC/MNC and band info. Next step is send SMS but there is an issue there so I may ask another question once I research it.
