Mobile Operator Codes /USSD Codes for Mobile Operators

Sometimes it happens that we forget our mobile number or want to know about our data (GPRS) balance usage, validity of sim, account balance or to stop or start a service provided by mobile telecom operator but we are unaware of the USSD codes or mobile operator code for that, also as market is flooded by so many telecom operators so it is very difficult to remember all these mobile codes.
That’s why I decided to put all major mobile operator codes/USSD (Unstructured Supplementary Services Data) here so that everybody can use them. There is a possibility that some of the codes not work in some regions , so therefore I request to all of my readers to paste latest mobile operator codes in comment section.
