How to save the SMS saved in the old SIM card to the new SIM card?

The most economical way is to guide you through your mobile phone. Replace the old card first, copy all the phone books on the card to the mobile phone, then replace the new card and copy the phone books on the mobile phone to the card. It's that simple. But if the mobile phone is an old model, it will keep you busy for half a day, because you have to copy it one by one. You might as well borrow someone else's good opportunity, choose to copy them all and get it done in a few minutes.

Supplement, just like saving a phone book. The demand for mobile phones is high, and some mobile phones are not as good as the short messages stored in the card. After inserting the old card, select a short message, press the option key or the menu key, and choose to copy or move the file to the mobile phone. Specifically, it may be different, something like this, and then copy them from the mobile phone to the card. This function is only available on high-end mobile phones. Ordinary machines do not have the function of writing cards. Send a text message if you can't borrow it. Re-send the SMS stored on the mobile phone. If the payee is yourself, they will all be pulled back to the card. Another method is to use Samsung's machine to copy the card to the computer with software, and then change the card and copy it back. It must be a Samsung machine.
