Learn how to PUK unlock the HTC U11 life. If you enter a PIN code incorrectly several times in a row, the device blocks you from attempting again and may also permanently damage your SIM card.
Confirm one of the following or similar error messages are on the device:
- "PIN code blocked. Enter PUK code."
- "Enter PUK code"
- "SIM card locked. Emergency calls only. Please contact Customer Care."
- Tap Phone to open the dialer.
- If your phone is not yet PUK locked, tap Emergency Call on the screen where you enter the PIN code.
- Enter **05*[PUK]*[New PIN]*[New PIN]# to unlock.
- When the phone displays 'Unblocking PIN: Registration was successful' tap OK.
