GSM MODEM : AT COMMAND to know my operator

Question

Can any one please let me know, is there any AT command by which I can detect the current operator name?

I have used AT+COPS? It returned me the numeric code for the operator: 0,2,40410

Then I used the command AT+WOPN = 0,40410 which returns the alphanumeric value for the operator

but that only gives Airtel operator's name, and for other operators it gives an error.

Please help me.

Answer 1

You should use AT+COPS=<mode>,[<format>,<oper>[,<AcT>]] command as was pointed out, but <mode> value need to be 3 to not to override your existing <mode> value:

<mode>: integer type
3   set only <format> (for read command +COPS?), do not attempt
    registration/deregistration (<oper> and <AcT> fields are ignored);
    this value is not applicable in read command response.

And <format> need to be 0 or 1

<format>: integer type
0   long format alphanumeric <oper>
1   short format alphanumeric <oper>
2   numeric <oper>

So your commands are

AT+COPS=3,0
AT+COPS?

Answer 2

You need to set the format first.

• AT+COPS=1,2

  "2" means numeric format, this will return e.g.40410

• AT+COPS=1,0

  "0" means long alphanumeric format, this should return the operator name string.

The first parameter is the <mode> - select the value that you need. For the full documentation of this AT command, see 3GPP TS 27.007 document at http://www.3gpp.org/ftp/Specs/html-info/27007.htm

When you have set the mode and format, then send AT+COPS? and you should get the operator name in the format that you want.
