This Mobile Backup 3 is a simple app that allows you to back up your contacts, SMS messages, bookmarks, and even call logs to an SD card. The backup files will be stored in the root directory of the SD card or in the phone storage. This app is very easy to use and allows you to restore your contacts, SMS messages, bookmarks, and call logs from any phone to another phone.

If you have an SD card, you should make sure that it is mounted on your device before running the app. If it is not, you will not be able to store the backup files on your SD card.
