I use Quik SMS, which does not support RCS. I keep getting missing group messages that only show up when I enable Google's messaging app. Upon closer inspection, it seems the messages are being sent not directly to my carrier via MMS, but to some Google address. This must be RCS right?
The behaviour persists even when I switch off RCS in Google messages. As soon as I switch back to Quik, group messages don't display.

This is what I needed, thank you! I couldn't find this anywhere.
Thank you for this. I didn't even know this was a thing... Hopefully this sorts out some of the issues I've been running into since de-googling
RCS messages are handled by Google and Apple, not carriers.
I've had RCS stop working before and I was subsequently automatically removed from group chats I was previously a part of (other members were all using RCS), and not re-added when I got RCS working again a few days later.
Something like that has probably happened to youEDIT: that's not it, misunderstood
RCS successfully working, even sent to iPhones, using Google Messages.
I know. The issue is that when I try to use an open source SMS app that doesn't support RCS, messages go missing.

What is RCS?
Its a messaging standard for interoperable Rich Communication Services.
Think signal, whatsapp, XMPP but for sms.
Unfortunately, while the standard is open. The servers many use are not. Google has a monopoly on them for android like imessage of apple.
There's some debate about how fully open the RCS standard is. There are apparently some undisclosed or licensed aspects that interfere with implementing the protocol in open-source applications. Here's an example of the debate from a few years ago. OP, the implication is that group chats in RCS might always be a bit problematic unless you are using Google, Apple, or Samsung apps.

I read the whole thread. But, I that's just one person who had no clue and was informed in the top comment about open source RCS implementation being possible.
I don't see any mention about group chats. I know for a fact encryption is a google side feature and not a standard RCS feature. So, even if you managed to create one you wouldn't actually be able to send RCS messages to most people since everyone would be using Google's chat service which uses E2E encryption.
Yeah, it's not a good citation. Thanks for adding the encryption angle. Also, RCS can't be or hasn't been implemented on budget flip phones. It's a shame really because these barriers prevent RCS from becoming a true standard.
XMPP is a good standard. It also supports client side encryption. Plus, the mobile clients are light enough to not cause issues and can run without needing too many resources.
Unfortunately, greed or company interests always appear to win one way or the other.

Use google message
You know it's against the aubreddit rules to recommend that, right? The reason I posted in this sub instead of r/Android is because I only want free and open source app recommendations.
Oh sorry, i didn't notice the subreddit name
