it works for me in punjab and for my other friends from other states ,
do you have same problem while sending msg to other numbers ,plz tell me the method by which you activated MO , msg no and other detail so that i can help yoou out
wat you can do is to find its activation method through the message not the cc,after finding the message number (ask your friends in your state ) just send a wrong message to this number(you can send abc ) and then you will recieve a message from the same number ,in which they (airtel)will provide all the detail about activating/deactivating their services ,Moreover which plane you are running monthly/weekly/day plan?
Simple...call customer care
then press 4 (Value Added Services)
and then again 3 (To talk to Gprs executive)
You will be directed to Gprs service and you can talk to a person and ask him/her for deactivation.
