How many times can I enter a SIM network unlock PIN?
Rules for how many times you can enter your SIM network unlock PIN are different for each phone manufacturer. As a general rule you should only enter an unlock code 3 times before you stop.
If you enter an incorrect SIM network unlock PIN too many times into your handset you risk blocking your handset. You will then need a PUK code or Defreeze code to unblock the handset or reset the counter.
It’s important that you do not play around with the handset and try entering an incorrect unlock code in the hope you can guess the unlock. Check with your network or handset manufacturer if you are not sure how to proceed.
