here i would like to publish the basic trick.
Step 1:
Check whether your sim is 3g or 2g.
if it is 3g Take a 2g SIM.
We need a 2G SIM.
Step 2:
Put one Month or 3 Day GPRS.
I Prefer One month plan because Data USage is Unlimited.
Step 3:
Upon activation of GPRS it take 10 min (minimum to activate).
In between this 10 Min try to convert your 2G sim to 3G SIM.
This can be done by sending START 3G to 121.
Rocking trik...
