Unicom's lock is dead. Can I receive the message?

The mobile phone card of Unicom Tencent Dawang Card has been locked, and no SMS can be received. Unlocking can be done in the following ways: the password of the SIM card is initially set to 1234, and the card is locked after three consecutive incorrect entries. At this time, you need to enter the PUK code to unlock it, but after the PUK code is entered incorrectly 10 times, the SIM card cannot be recovered.

You can check your PUK code information in Unicom mobile phone business hall or Unicom online business hall:
