If you've blocked your phone by entering an incorrect PIN too many times, you'll need a PUK (Personal Unblocking Key) code to unblock your device. If you require a PUK code, please get in touch with iD Mobile via live chat.

Once you've entered your PUK code, you'll be asked to choose a new 4-digit PIN of your choice. After that, you’ll be unblocked and good to go again.
Entering the wrong PUK code
You have 10 chances to enter a correct PUK code. After that, your iD Mobile SIM will be blocked.
If your PUK code hasn't worked after the second attempt and you're convinced that you've entered it correctly, it's probably best to contact iD Mobile via live chat so they can help you.
Make sure you're requesting for the right kind of code
Don't get confused between a PUK code and a PAC code.
A PUK code unblocks a phone when an PIN has been entered incorrectly too many times.
A PAC code is obtained when someone wants to leave a service provider and use their device on another network.
