i think third price increased,remember i have recharge 1 gb for dongle @Rs.100 only on previous year ,really bad news for airtel customers,but best speed data pack means first vodafone & after airtel:tup
better i suggest all to move to postpaid, currently im in 299 plan with 1gb 3g and 600 min ( std/local mins free) and 150 national/local sms free and cug free
