The mobile phone is locked, depending on whether you mean the mobile phone itself is locked, or the mobile phone card is locked, if the mobile phone card is locked, go to the business hall and ask the waiter to unlock it, free of charge.

The PUK code is a personal unlock code that is used to unlock the PIN (personal identification code, consisting of 4 to 8 digits of Arabic numerals, which can be changed by the customer at will). When the wrong PIN code is entered three times in a row, the phone will lock the card by itself, and the correct 8-digit PUK code must be entered to unlock the card. After locking the card, the phone screen will display the words "Enter Puk", "Block", "Please enter the PUK code", "SIM card is locked", etc.

Note: If you enter the wrong PUK code 10 times in a row, it will cause the card to be burned, i.e. the card will be permanently locked.

A PUK code is a set of 8-digit numbers that cannot be changed. The PUK code will change when the card is replaced.

2) "Card blocked unblock?" is displayedThis situation mostly appears on Ericsson mobile phones, and the unlocking method is: press "yes", enter the PUK code, press "yes" to enter the "new PIN", press "yes", and then enter the "new PIN";

3) If "SIM card blocked" is displayed, the unlocking method is the same as in (1).

4) Samsung models show that PUK is not on, then there is only one chance to enter the correct PUK code.

5) Nokia directly enters the PUK code.

Note: If the mobile phone shows "blocked contact card provider" or "card disabled", it means that the card has been scrapped, and you need to bring the relevant documents or service password to the service hall to apply for a replacement card. ”
