If a SIM PIN security code has been entered incorrectly multiple times, the SIM will lock and require you to enter a PUK code to use your device again. Be careful! If you incorrectly enter your PUK code 10 times, your SIM will need to be replaced.
- Make sure the device is asking for a PUK. If it's asking for a PIN, try the default SIM PINs of '1234' or '5678'.
- If you get a prompt about a PUK code or your SIM is locked, Contact Us to request your PUK code.
- If you're prompted to enter the PUK code, enter it. You may need to attempt a phone call before you are prompted to enter the code.
- Enter your PUK code in the [PUK] field.
- Enter your SIM New PIN code in the [New PIN] field. You must enter it twice.
- If you're not prompted to enter a PUK code, open the phone dialer and enter SIM 1 **05*[PUK]*[New PIN] *[New PIN]# or SIM 2 **052*[PUK2]*[New PIN2]*[New PIN2]#.
- USSD short codes must be enabled on your device for the PUK unlock code to work.
