How does Samsung 5570 transfer the SMS stored in the mobile phone to the sd card?

I'm a mobile phone, just like yours, and it's also a Samsung S5570. To transfer the SMS from the mobile phone to the SD card, you can do it directly through the mobile phone. First, open the inbox of the mobile phone, open the short message of the contact person to be transmitted to the SD card, then press the left soft key of the mobile phone and select "More", and one of the options is "Copy to SD card". In fact, it will be more troublesome to transfer such a short message from a contact. If you want to transfer the short messages of all contacts in your mobile phone to the SD card, you can use the guard in your mobile phone. I use 360 security guard, which has SMS backup function, and directly backs up all SMS to SD card. As for installing the mobile phone suite on the computer, I don't recommend you to do it. I have downloaded Samsung's suite before, and it is really troublesome to use.
