Thank You Messages Or Helping How Can I Set My Samsung Phone To Save Text Messages To The Memory Card?

How can I set my Samsung phone to save text messages to the memory card? - thank you messages or helping

I have a Samsung A707 phone and my inbox is filled with text messages. Is it really necessary for most of my messages, I know if there is a way to transfer all my messages wonders on my SD card? I transferred all my pictures on my memory card, but I can not understand how I transfer my SMS messages.

Thanks for any help
