Hi guys, i need to send SMS using GSM Modem. My modem is D-Link and model number is DWM-151.
I have successfully completed the SMS sending process but the problem is, some time modem is failed to registered with the GSM network service provider.
AT+CREG?
returns 0,0
modem is not registered and not searching for a home network.
So i decided to registered manually using AT+COPS command.
AT+COPS=1,2,"40480" //404 India MCC 80 BSNL MNC
But the response is ERROR.
I don't know what's wrong and how to achieve this ...
If you any one knows explain me guys, waiting for your guidence
Thanks in advance
