After the PIN is locked, it can only be unlocked with PUK, if it is a CDMA card, the PUK code is printed on the card. If the card has been thrown away or there is no print on it, you can only find the business hall where you opened the account and you must have a valid ID of the owner to check the PUK.
You can use the PUK code to unlock the network card, when the PIN code is locked, and prompted to enter the PUK code, do not act rashly, because the PUK code is only 10 input opportunities, 10 times are wrong, the SIM card will be permanently locked, that is, scrapped.
You can call the customer to inquire PUK code, in addition, when buying the card, there are also marks on the card sleeve, you can also log in the telecom online business hall to inquire, there are marks in my information.
