first activate 2g sim into 3g by sending sms 3G To 121 follow procedure said by message in your mobile .then recharge smallest 3g pack 7/8/9 Rs. then recharge with 2G plan u will get unlimited speed . Same trick I am going to check with bsnl as i heard & found in internet.
But this trick is stopped to me bcz 3g plan of 8 rs. was for 1day So this trick has worked to me for 1 day.
