I've been having this problem (suddenly became unregistered and can't re-register) for five days or so now. I've tried every guide and advice out there, even went through the Google Messages debug menu to forcibly unregister and try to re-register. Nothing works.
Using RCS with Google Messages on GrapheneOS
Similar issue here. I had RCS disabled for a while since I was skeptical of Google Messages, but I decided the pros outweigh the cons. When I tried to enable it, it refused to activate and I've tried basically everything suggested online. I'm currently trying to wait two weeks with RCS deactivated; I'll report back on the 29th.
5 days later
just install google messages and already enjoying the full feature aspect of messaging.
not sure about the RCS and dont really care. just want a modern texting experience.
The rcs doesn't work for me either.
N3rdTek I now have reason to believe SOMETHING has changed within the OS to cause all these RCS issues.
The Google RCS implementation entirely relies upon Google apps and services. The OS has little to do with RCS it is all done by the apps. It is far more likely the change that broke this for you happened somewhere other than in the OS.
As this does not appear to be hitting everyone there must be something common with the people encountering this issue.
It could be that some dynamite modules need to be downloaded into Messages. Do you have network granted to all three Google Play apps? If one of them has it it does not make much sense to deny it to the others. Play Store updates dynamite modules.
It could be something related to your carrier. Have you tried installing the Carrier Services app ?https://play.google.com/store/apps/details?id=com.google.android.ims&hl=en_US&gl=US
Do you have DNS filtering that could be blocking a critical connection? If so you could try disabling that.
jufstp i am referring to the app. every other 3rd party app seems hacky or limited etc.
Carlos-Anso I've already checked all that. Looking at the Google help community, it looks like several non-GOS users have the same issue. For now, I'm just going to forget about it. Hopefully this gets fixed in the future.
Carlos-Anso Hello, I just reinstalled Android stock to test if RCS works, and well they activated immediately. I don't know if it's a problem with grapheneos but it's something to look into.
I wonder if it could be the cellular provider causing the issue. I've installed the three google apps and the messages app and RCS is active after a minute or two. Turn RCS off, turn it back on and it is active again within a minute or two. I delete all the apps from GOS, restart phone then reinstall and start over - RCS activates.
I did a factory reset on my GOS Pixel 7A and then proceeded to start from scratch and again RCS activated within minutes.
The three Google apps from GOS apps app, messages and minimal permissions and RCS works.
It's the weirdest thing reading all the issues with other GOS users
billinmtl Which apps (Google) did you install? Are any of those apps beta versions? What permissions do they have? Was it activated on Wi-Fi or cellular data? Did you have to add your number to the app to verify, or did it show up without the need to? Did you navigate away from the verification screen before it was complete? Are you on any VPN (on device or otherwise)? Any DNS settings applied (on the device or otherwise)?

I installed the Google Play services from the apps app -none are beta releases. (Google Play services, framework, and Play store). I then installed the Google messages app.
These were the permissions recommended on this thread, and are the only ones I allowed
Activation of RCS worked immediately for me as per the settings detailed
GSF: Network
Play Store: Network
Messages: Phone, SMS, Network
Initially, I get what looks like a sim card and my phone number with a message saying RCS is not available. I exit that screen to complete my other settings within the app and then go back to the RCS screen and it shows activated. Guess it takes my cell network a few minutes to confirm and authorize.
Edit, set up was completed with my VPN on
I have followed this process being signed in to play store with messages downloaded from there as well as not signed in with messages downloaded fromAuroraStore - same results.
billinmtl Thank you for your feedback. What about the Play Services permissions? Under Messages settings — Advanced, is your Phone number “Unknown” or set to some value? Is your cell number also registered as a 2FA with Google?
- Edited
Under advanced settings my phone number appears. I did have RCS activated on stock prior to installing GOS but not sure it was registered as a 2FA, will need to look into that
Edit - my phone number is not registered 2FA with Google
I'm not sure if this will work for anyone else. I turned on SMS in GPS already had Network only". Messages has Network, Notifications, Phone and SMS. I went into Messages Settings and turned on RCS. It still said too many attempts try tomorrow from trying the last few days. After turning on RCS and waiting an hour I said "hell with this". I went into GPS settings and turned off the SMS permission and went back to Messages as I planed to turn off RCS and to my surprise it activated. It's been on solid ever since. Try turning RCS in Messages settings then, untick SMS in GPS then check it.

Hello, I've just realized that after 1 year of use, the RCS is still in configuration...
