If you enter the PIN code three times incorrectly one message will be shown "ENTER PUK" Then if you again enter the puk 10 times incorrectly"SIM REJECTED"
After these your sim-card will be completely damage.
Therefore, just throw away the old Sim and get new one.

Put your sim card on another phone (should be unlocked or the same provider) and see it it works.

Put another sim card on your phone (should be the same provider sim) and see if it works.
