SMS Import / Export

SMS Import / Export imports and exports SMS and MMS messages, call logs, contacts, and blocked numbers from and to (ND)JSON / ZIP files. (Contacts import and export are currently functional but considered experimental.) It does not require root.

SMS Import / Export is a sibling project to sms-db, a Linux tool to build an SQLite database out of collections of SMS and MMS messages in various formats. sms-db will hopefully eventually be able to import ZIP files created by SMS Import / Export, and to export its database to ZIP files that can be imported by SMS Import / Export.
