GSM MODEM : AT COMMAND to know my operator

11
votes

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.

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?

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.

Works for my Quectel modem.
