My mobile nos is 9939356270. i had lost the sim and so had got it blocked and have re got it. But now every time i try to activate it, the message "sim registration failed" pops up. i have tried changing handsets and calling on the customer care center but to no avail.
i have life time validity and the sim was working perfectly before i had lost it.
please take prompt action as i am in dear need of the no. and have no complaint against airtel service in any other way.
