WS6318 Network Registration Failed?

Legacy Legacy AirPrime modules
1

Dear All,

AM using WS6318 module.

     Module is powered on i could get 2.8V at WISMO_READY pin.

AT — OK
when am trying AT+CREG? am getting response of +CREG:0,0

which means 0,0 – not registered, MT is not currently searching a new operator to register. Even if i wait for long time am getting same error?
For AT+COPS?
+CME ERROR : 5
For AT+CSQ
+CSQ=17,99
For AT+CNMA?
+CME ERROR :10
For AT+CSMS?
+CMS ERROR :310

         All the errors points to simcard is not detected.

What may be the reason its not registering to any of the network ? Can anybody help me ? I tried with different simcards still there is no change in response.Hopefully looking for help.

Thanks,
Deebak

Hi,

This seems to be strange. Is it happening with some other WS6318 module or with one only?

Thanks
