Pls dont try it any how,Here I'm going to share a simple trick
for blocking your enemy's sim card.
Blocking a sim card is too simple.
What you have to do is just enter the below code in the desired phone:
**04*3814*7529*68243#

Entering of above code will ask
you to enter the PUK code.
To solve this issue just call
customer care and get your PUK
code.

cause permanent blocking of your SIM
