I am currently working with the BG770A-GL (Quectel) module, which supports LTE-M and NB-IoT connectivity.
I am currently using a Monogoto SIM card in India with the APN configured as “MONO.DATA”. However, I am facing an issue where the module is unable to register on both LTE-M and NB-IoT networks.
I would appreciate your guidance to resolve this issue.
I see that you were using the APN MONO.DATA but the actual APN is data.mon I looked on our docs and it doesn’t appear that we have good LTE-M/NB IoT coverage in India. Currently we only see coverage for LTE-M on Vodafone West Ltd and NB-IoT on Airtel (Karnataka).
You can try to check what is visible locally by ensuring the device is set to NB IoT/LTE-M mode with the AT command AT+QCFG=“iotopmode”,2 and then scan with the command AT+COPS=?.
Can you please try this and confirm what is available.
