The mobile phone card is locked, so I can't receive the message. How to log in to the mobile phone business hall?

If your mobile phone card is locked, you can unlock it according to the following traffic:

The password of the SIM card is initially set to 1234. If the error code is entered three times in a row, the card will be locked. At this time, you need to enter the PUK password to unlock it. However, after entering the error code 10 times, the SIM card cannot be recovered.

If your mobile phone has a service password, you can check your PUK code information through the telephone lobby or Internet lobby, and you don't need to receive the verification code.
