Samsung Rcs Not working. Chat settings says register failed

[Ozjasmine1]

Long story short. I had to take my sim out of my galaxy 20 note ultra to a dinosaur Samsung phone to contact my husband as my phone was not fully charged. Once house power was back on I charged my phone and inserted my sim back in. The chat in samsung message however had changed from the RCS (I think that's what it is called) that it was before. When I go to open chat messages it tells me what it does and I click on ok. Then it does this glitch thing and comes up registration failed. I've tried everything to clearing storage to all the possible YouTube quick fixes and nothing works. I'm still using mms. I can use google messages with RCS fine but I hate the layout of it and just want my original set up back. Anyone else have similar problem or have a solution.

Hi to activate the Rcs in Samsung messages you have to toggle on rich communications first in more connection settings.

Yeah see I don't even have that option. Checked my husbands phone. His is working fine from Samsung messages and he doesn't have that switch button either. I'm wondering when I took out my sim and put it in a phone that doesn't support it maybe the service automatically disconnected that option for me.

OK sometimes it takes a few days before it starts working again.

Hi try searching on Samsung members there's previous posts of fixes that you can try.

I was having a similar issue where I'd select the "Chat Settings" option and they it would ask me to "Start" to register, but then a few minutes later it would say "Registration Failed". I found a way around this by going to Settings > Connections > More connection settings, then toggling off Rich Communications. Then try selecting the Chat Settings again and it should now show the options. When you revisit the Rich Communications option you should see that it's now been toggled back on
