SMS Backup is a very simple app that makes a backup of your SMS and MMS messages (images and audio files), lets you share them and then restore/transfer to another phone (currently only SMS). Important notice: - This app doesn't restore deleted messages. - If you're missing some messages or one side of conversation in your backup, it's probably because this app doesn't back up RCS messages (also known as Advanced Messaging) unless you use Google Messages as your default texting app. Turning Adv
