How annoying! Unicom card is locked, how to receive SMS?

If the PIN code of Unicom's mobile phone card is locked, you can contact the operator to check the PIN code and unlock it. If the PIN code is entered incorrectly 3, you need to enter the PUK code. If you enter the British code incorrectly for more than 10 times, you need to bring your certificate to the business hall to consult for card replacement. Remind you: the specific situation is subject to the operator, and the number rules of each province and city depend on the local situation.
