Using RCS with Google Messages on GrapheneOS

Novastatic I have never reached out over the phone... (650) 253-0000 is the one I can find. Not sure how far you will get.

Do you have another phone around where you can pop your sim in and got through the process without use shizuku or any adb commands or mod apps

RCS just stopped working on my phone after going strong for awhile. I didn't change anything except for doing a GrapheneOS system update, though it was still working for a few hours after the update. I confirmed with app opps that messages and play services can still read hardware identifiers..

I reinstalled Google, allowed my number to be automatically verified with Google again, and handed over all the positions to messages, play services, and Google (replacing storage scopes with full storage access), cleared cache for messages, reinstalled messages, and restarted my phone a few times.

No dice so far. Any suggestions? Did anyone else lose RCS recently?

biscuit_tosser_88 Thank you

by deregister, do you mean turn off RCS in Google Messages? I did that.

I ended up getting it working, but I had to completely uninstall play services and Google messages and then redid the setup process from scratch that I outlined in an earlier comment.

Part of me is thinking this happened because I turned off the automatic phone number verification Apps -> Sandboxed Google play -> Google Settings since I thought it wasn't necessary.

After I got RCS working the first time, I thought I could turn it off after getting RCS to work initially. But I guess Google tried to do another phone number verification, it failed, and then RCS stopped working. After redoing everything after reinstalling play services, I received an SMS message saying "Google is verifying the phone# of this device as part of setup. Learn more: [link]"

And then just like that, RCS was enabled again.

If my theory is correct, the only thing that I'm still trying to figure out is why I had to re-install Play Services and messages to get it to do this check since I had already toggled it on earlier with no effect.

I'm also not sure why it needs to be enabled for RCS to work on GrapheneOS, but I never had it toggled on when I was on stock and RCS worked just fine.

When I anable the debug mode with *xyzzy* and check Report RCS Connection State it says

Carrier RCS is not set up
Transport: UNKNOWN
ACS url: [not connected]
PCSCF: NOT_AVAILABLE
Sub Id: 2
SIM Slot: 2
SIM Carrier: Your provider
SIM Nmber: 
Rcs Apk: Bugle
Rcs BOE: Optimized
GmsBinding: Enabled
App StanfBy Bucket: 10
Background Restricted: false
Etouffee provisioned: false

I take it that maybe RCS need's to be enabled by my network carrier?

Daxard Nope :(

Novastatic Back after 24 days, I had given up and forgot about this. Now it's magic working again today, and I can verify cause I sent a text to my mom and we both see it as RCS.

My previous steps were based from other posts I saw, and were still enabled at time of enabling:

• Allowing almost all permissions to Google Messages (even audio, mic, camera, etc.)

• Read device identifiers via Permission Manager X (Shizuku and AppOps would've worked too)

• Network for Carrier Services (but phone permission wasn't on?)

• Play Services has contacts, network, phone, photos/videos, notifs, and sms. I might take away phone/video and contacts later

• I saw CarrierConfig2 in system apps and deleted the data for the app. Only permissions was the default sensors

• Sandboxed Play Store only has Network and Notifs

• I did have auto phone number verification on

• I deregistered my number on iPhone weeks ago, probably around the same time of my last post (3 weeks) so maybe that caused issues

• I had the official Google app from the Play Store, but I'm definitely gonna delete it. It had almost all permissions, can't remember which ones

Maybe the magic really is waiting a few days to a week, but that sucks man. Hope this lasts, I'll see if updates break it or not.

Edit: I also changed my Data to use 5G instead of LTE only, but RCS set up while having both data and WiFi on. I normally have my phone on Wi-Fi and airplane mode to ensure data isn't being used, so idk if that causes issues with RCS. Obviously, my VPN and Killswitch was turned off.

I cleared the data and cache of Messages, carrier services, that CarrierConfig2 system app I mentioned, and rebooted before I checked.

reluctantrecluse Edit: Scratch that. Of course as soon as I make an account to post here it just decides to work... Patience is a virtue.
