How come there are no original text messages when I put the SIM card in Nokia 2680s?

Try using a new phone to check the storage status and see how much % of the SIM card is used. It may be caused by inconsistent formats when the two phones store things in the card. Of the two mobile phones I used before, the old one obviously saved text messages on the card, but when I put the card into the new phone, the storage status showed how much % of the phone book had been used. In fact, I didn’t save a single phone call to the card. inside.

Method: Put the card back into the old machine, delete all messages and phone calls, and then put it back into the new machine.
