Why is the SMS display number of Apple 13' s new card unavailable?

This situation is caused by the fact that the mobile phone cannot detect the sim card.

You can turn it off and re-insert the card, and then turn it on after confirming that the card is installed correctly! First, users can turn off their mobile phones and try again, or upgrade the version of the mobile phone system to see if it can solve the problem. If you can't solve the problem, it is the problem of the mobile phone. Users can put the SIM card in other mobile phones, send short messages and exchange them back.
