If I change my mobile phone instead of my card, are there any messages saved in my card?

According to your settings, most short messages are stored in your mobile phone (usually only a dozen can be stored in the SIM card).

Photos are stored in mobile phones or memory cards. If you can connect this to the computer, you should be able to send it to the computer.

Finally, it is my experience. I often edit short messages on the computer and then save them. I use a mobile card, which can be used in the computer version of Fetion and then send myself short messages (free of charge).
