How to save the short message content in the memory card?

You can download a computer suite with a matching mobile phone model. You can see your phone number, text messages and memos in the suite. Create a txt text document in the computer, copy and save the short message in the mobile phone e-book, so that you can read the previous short message through the mobile phone e-book. If your mobile phone is fake, it won't work. This is a bit difficult to achieve.
