WHEN U SEND A MESSAGE FOR GPRS ACTIVATION U RECIEVE MSG LIKE GPRS ACTIVATED SUCCESSFULLY. BUT SOMETIMES U RECIEVE MSG LIKE SERVICE NOT AVAILABLE OR ELSE.
THIS MEANS THAT AIRTEL SERVER DOES NOT UPDATE UR ACTIVATION AND WE CAN ENJOY FREE MOBILE OFFICE FOR LIFE.
I AM USING IT SINCE 20 DAYS.IT DEPENDS ON UR LUCK
IF U R USING THIS TYPE OF FREE GPRS THEN DONT OPEN AIRTEL LIVE OR OTHER PAY SITES LIKE MAUJ,INDIATIMES ETC
