In the past, the card in the mobile phone deleted the text messages inside. What should I do if I switch to IPHONE, and there are still deleted SMS messages after each restart?

The solution is to insert the sim card into other mobile phones that can directly operate the sim card (for example, your original mobile phone) and directly delete the short messages in the sim card, so that those short messages will not appear again every time you insert it into the iPhone.

It's useless not to directly operate the sim card every time you delete it on the iPhone.
