I took an airtel sim on february month number is 8897012242 i did a big mistake for choosing to take an airtel sim because from starting onwards i faces some problems first problem is about offers after that registration problem. It is the mistake done by the dealer to didnt supply the proofs at in time. For that reason i didnt get outgoing for a week and i submit my proofs at airtel main office, after that yesterday i.e 16-03-2010 idont know what happened suddenly the registration is cancelled and when i asked to c care they said please go to help center and submit proofs. How many times i have to submit my proofs to be frank i choose airtel just just only for signal that’s it not for an worst offers. sorry this is to tell how ur dealers are playing with us not for to activate my sim because i took a stange decision to never use airtel services in my life
