Use AT+COPS? Command to check whether a carrier is connected.If there is no base station signal at the location of the device, it may cause AT+CGREG? Command return error.
This means that the device is not currently registered with any network operator.Check that the SIM card is installed correctly and activated please.
Thank you for the answer. I will check the registration with
My network provider
Sorry,I didn’t check properly before and you need to check that your antenna is properly installed because +CSQ: 99,99 means no signal.
