Hi,

There could also be a SIM card issue. If you receive an error during AT+QIACT and +CGPADDR always returns 0.0.0.0, I recommend checking the SIM card.

AT+CPIN?

+CPIN: Must be READY. If a different value (e.g., SIM PIN, SIM PUK, SIM not inserted) is returned, the module cannot use the SIM.

AT+CGATT?

It should return 1. If it returns 0, the module failed to attach GPRS to the network. This also occurs when the SIM’s data service is disabled.

AT+COPS?
AT+QNWINFO

If the operator name is not displayed, the SIM may either be malfunctioning or not registered with the network.

Can I see the AT+CPIN?, AT+CGATT? and AT+QNWINFO outputs? Based on that, I can clearly tell if it’s a SIM or an APN.

If there are no errors with AT+CPIN?, AT+CGATT? and AT+QNWINFO, then you can try the code below to get a quick answer.
