Why can't the mobile phone display short messages after changing the 4g card?

The possible reason is that contacts and text messages are not stored in the card, but in the mobile phone. At this time, you need to use some backup tools, such as WeChat.

Check the contacts in the contact settings to read the contacts in the business card.

Find another mobile phone card, see if it can all come out and judge whether it is a mobile phone.
