I use airtel prepaid connection for the last many years. The new number which i have been usung since Jan 2011, phone number 9746579079, is an important number for me.Even though It offers lifetime validity, it expired on 7th may 2011. Now it shows in valid sim. Kindly do the needful to reactivate the sim on which i do all my transactions. Santhosh kumar P.A Pulianmackal, Kannur, read full review »
