Where is the old machine open the PIN lock, my PIN is locked

As you mentioned, if you use a China Unicom mobile phone number, you need to use a PUK code after the PIN is locked.

To unlock, the steps for PUK query and unlocking are as follows:

The PUK code is 8 digits, and you can use your USIM card yourself.

After querying the PUK code, when the mobile phone screen prompts you to enter the PUK code, you enter the PUK code normally, and the PUK code will be prompted to enter the PIN code again after the PUK code is successfully unlocked.

In this case, you need to set a new PIN code. The PUK code only has 10 chances to enter, and if you enter it incorrectly 10 times, the SIM card will be permanently locked, that is, it will be scrapped. You will need to go to the sales office to replace the card before you can reuse it, so please enter it carefully.
