Urgent! Mobile phone missed receiving other people's text messages!

There should be something wrong with your mobile phone card. I've been in this situation, but I can't get a text message. Finally, I went to the business hall to get a new card, and the problem was solved.

Be sure to copy the information in the mobile phone card before handling the card! 15 yuan can get a new card. You can get a card for free by pre-storing the phone bill in 50 yuan. I don't know if I can do it now.
