RCS shows connected but not online

[AA_Ron]

Just got a new pixel 9a for my wife so I transfered over everything and moved over the physical sim.

I thought everything was working, but we discovered that she wasn't receiving texts, her old phone was receiving them all.

So I disabled RCS on the old phone.

I checked and RCS was still not working, so I followed the instructions, turn off RCS, force stop, clear data in the messages app, reboot, turn on RCS... and it shows connected! 

But when I send a text to her it shows she's offline and doesn't send.

Is there something more I need to do?

When I popped the sim card back into the old phone and re-enabled RCS it re-enabled itself without issue and I was able to send her messages.

After failing at trying all of the solutions and with my wifes phone being a day out of date I factory reset the phone, turned RCS off on the old phone and then re-initiated the new phone install process...

After doing this it actually stated that the phone wasn't compatible with RCS...

I proceeded to install the latest system update and to update any app that needed an update...

After doing that I rebooted the phone and RCS finally connected.

Maybe I needed to do all that? Maybe Google just needs time for the old phone to be deregistered from RCS? In any case this fixed the issue.

if you register RCS again, it should work

@AA_Ron 

RCS does not register to the sim slot

If the new phone shows registering, it is good,. sometimes it can take long for it to register, it is an issue on Google side

If it tried to register for over 4 hours, please try what I suggested again, Uninstall Updates, Reboot phone and Reinstall and then Register RCS again

@softech so it looks like the messages app was not updated to latest. So I updated the app, rebooted, re-enabled RCS and it still won't work, just sits there connecting.

Maybe because it's a physical sim that was connected with an old phone likely with the RCS registered to the old sim slot? Should I contact public and switch to an esim?

@softech unfortunately there is no ... menu in app info so the messenger app is the one that came with the brand new phone and I can't uninstall them update

@AA_Ron 

sorry, I meant uninstall Google Message app.  

Yes, it is built-in on Pixel, so you likely just see the option Uninstall Updates.  Click that to return it back to the version it came with the phone.  Then reboot and Reinstall the update, and reenable RCS from Google Message Settings

[AA_Ron]

Note: on my older pixel I have a uninstall updates from the ... menu in the upper right of app info, but on the new phone there is no ... menu

@softech thank you

I'm not sure what you mean by uninstall RCS?

Google messages is built in to the phone and I can't seem to uninstall it or uninstall updates. Since it's a brand new phone it just installed the latest on setup.

I can turn off/on RCS and that worked for getting RCS to connect, but once connected it still didn't seem to be working

@AA_Ron start with the obvious, make sure Wifi or Mobile data is on

and if that is not the case, try to uninstall RCS first (instead of full uninstall, it might only give you option to Uninstall Updates, which means go back to the old version it came with the phone), then reboot phone and reinstall RCS (or update in some case).  Enable RCS again and it should work
