How to save the short message to the mobile phone?

I haven't used it before. Let me use my brand-name mobile phone for your reference. Open the SMS directory and click Options. There are settings in the options. Press Settings, and there are storage locations in the settings. Press the storage location, there is a memory card and a mobile phone.

You can use a dual-card dual-frequency mobile phone to send short messages of this card.

Go to another card, then format this card and move it back.

You can also connect the mobile phone to the computer with a data cable, open the mobile disk, then open the short message directory, copy it to the computer, format it, and then copy the information back.

I hope I can help you. I wish you happiness every day!
