new bsnl 3g trick

i think any bsnl 3g net trick working now but i despertly want to use 3g so i got a good idea buy a 3g sim which cost 59 and in place of frc 120 frc 51 rs u will get 0 balance and 6gb net for a month total 12 gb for 2months but morning 1gb night 5gb. After 2 months again buy a new sim. Thatsall. so andhra pradesh guys enjoy i came to know 51 frc from a.p bsnl site. Even i confirmed calling c.c. Other regions peoples also check about 51 frc.
