How can I trace an SMS?

Hi All,

 I would like to trace SMSC number (whare is it and who is the provider?)
For example:

someone send me SMS with fake sender id, but I got SMSC number by retriving
the SMS by AT command.

some of the SMSC id I got:

1312211127101661
2132123121264111
2111111466338112
1312014213946101

What dose these numbers mean? And how I can get more information about them?



Kind Regards,
Bader Geffari
