# RCS Exporter
I've been using the app SMS Backup & Restore for years. After getting a new phone and transferring the messages over I noticed some were missing.
I tried to find out why this is happening - because of a "new" message type called RCS: https://en.wikipedia.org/wiki/Rich_Communication_Services
Essentially those messages are stored in a separate database on the phone, hence not considered regular text messages.
The above mentioned program is not able to export those messages (as of September 2021).
I didn't want to reinvent the wheel - there are already enough backup/restore apps for SMS and MMS. Instead I just wanted to be able to export the RCS messages, too. Preferably it should be a format the SMS BR can then import.
So if you're interested:
1. Backup your SMS and MMS messages with another program.
2. Import them on the target phone.
3. Export the RCS using this app.
4. Import those on the new phone as well.
Remarks:
- This program has only been tested with text messages. I don't know if images, etc. can be exported as well.
