Which file can be found in the mobile phone card for SMS storage?

First, set the SMS memory as a memory card.

Secondly, you can't read the short messages in the memory card, you can only back them up.

The folder where short messages are stored is called a "private folder". Copy it. After copying, if the mobile phone card is formatted, you can take it back and read it on your mobile phone.

Those short messages can only be read from mobile phones with PC suite, or through mobile phones.
