  • Using RCS with Google Messages on GrapheneOS

rcs works for me, I changed my subscription from free to bouygues and it works

    As far as I'm aware there's no way to get RCS working without the Google Play Services? Can someone confirm that I have that right ?

    For what it's worth, things I did to get it to work;

    • used default "Owner" profile
    • installed google play services, permissions Contacts, Network, Phone, SMS
    • installed carrier services, allow Unrestricted running in background
    • installed Messages, permissions Contacts, Network, Phone, SMS, storage spaces setup, set SMS app to Messages
    • chenxiaolong this step here
    • turned off any VPN, WiFi (to use mobile data)
    • open Messages, turn on RCS
    • wait around 5 minutes
    • working!

        New install of graphene and RCS works pretty much out the box. Did nothing but install Google messaging, turned on RCS, typed in my number and that's it. T-Mobile US is my carrier, no carrier services installed.

          Ducter I don't know if you'll run into the same issue I did. It initially behaved that way for me too (also T-Mobile USA), but Google would silently block access a day later. After the silent "ban", RCS would show as connected, but actually sending and receiving messages would fail. It wasn't until I granted the READ_DEVICE_IDENTIFIERS permission (https://discuss.grapheneos.org/d/1353-using-rcs-with-google-messages-on-grapheneos/352) that it stayed working (a little over 2 weeks for me now).

              chenxiaolong I've tested between phones and it works but it's only been a couple days and you're correct, it could stop at any point. Maybe I'll go on and enable that just in case.

                chenxiaolong Thank you, this finally got it working. Been trying all the steps people suggested for months now, completed this, rebooted and instantly connected.

                  Sad, I just refuse to have GPS installed on my main profile or have it exposed to my texts

                    graphosor Agreed. I also don't like the idea of google getting access to your contacts, which I presume (?) would allow them to figure out who you are.

                        I think it's needed beacuse a part of the RCS standard talks about checking if the recipients number is also using RCS. I will have to check on this as they can get your SMS conversations and numbers with the SMS permissions.

                        It might just be add contact pictures and other info locally ,

                        Now if they are sending that data of device I can not say as I don't know

                          For the people that have it working:

                          1. What's that minimum amount of permissions you need to give to Google to get RCS to work, across all necessary apps?
                          2. Does it need to be on the owner profile?
                          3. Can you have SMS messages go to other profiles as well or would that mess it up? If you can, which SMS app should I use since Google messages won't work on a profile without play services?
                          4. Do you need to be logged into a Google account?
                          5. Will I have problems with Verizon (US Mobile)?

                          I'm trying to see if it's worth trying to get Google Messages. RCS is far superior to SMS/MMS and offers encryption with other Android users. But if I have to hand over too much data to Google to get it to work, it may not be worth it.

                          Is it possible to use RCS on a work profile or is this only working on owner profiles? Also does anyone use Google phone and does it improve call quality over the standard graphene phone app?

                          I'm stuck at "setting up" and verifying the phone number in the RCS settings.

                          1) Is there a source of truth for instructions to get RCS working? The instructions seem to be all over the place in this thread. I don't know what the latest is.

                          2) is it possible to set up RCS on a user profile or only the owner profile (or both)?

                          3) Are the any known problems getting RCS working on Verizon (in the US)? I saw some point fingers at Verizon in another thread but it wasn't confirmed.
