Why does my mobile phone only display the number when sending and receiving text messages?

Is your phone number stored in your mobile phone or SIM card?

It is suggested to try the card before changing the mobile phone to see if it is a mobile phone problem or a mobile phone card problem.

If other mobile phones cannot display normally, the mobile phone card is out of order. You can check it in the business hall.

If you can use it by changing your mobile phone, it is that there is something wrong with your previous terminal, where did you buy the mobile phone, and it was still after-sales maintenance.
