Is RCS an open standard? I’ve seen some people say it is and others it isn’t and now I’m very confused. Can you please give me a definitive answer?
The confusion stems from the fact there no APIs in Android that let apps use RCS. Only Google can use it on Android and no other apps can use it. Anyone can make an SMS app. Only Google can make an RCS app.
It is an open standard, meaning you are free to create your own operating system for phones that implements RCS. But Google doesn’t let you use it on Android, so in practice it’s closed.
Plus, Google’s implementation of RCS adds extra features (like encryption) that aren’t part of the standard. So even if you create your own operating system that implements RCS, it will still be incompatible. So that’s another reason it’s not really open.
That seems incredibly dumb and backwards. I guess doing it this way helps them expedite its death like all their other products lol
I was about to say the dumb and backwards part was not having basic stuff like encryption in the standard. 🤷
This is because the telecom providers were apart of designing the standards and implementation but did not care about it and Google released their own service for it. There is no money in it for the telecom providers to support it.
It would also let them claim that its an open standard that anyone can use and they’re contributing to open source, even if no-one could effectively use it in the same way that they implemented it.
It’s XMPP all over again.
Only Google can make an RCS app
Yes and no.
You don’t need to make your own OS, but you do need to implement support for the RCS protocol within your app, rather than piggyback on Googles APIs.I don’t like it, but there’s no legal requirement for google to provide those APIs, like they did with SMS etc.
That’s fair but that also means their “RCS” is really just a name they slapped on their latest proprietary messaging platform.
We know they’ve been trying to get ahead in the messenger game for many years, now maybe they figured if they use the RCS angle it might get some traction.
Or maybe I’m completely off, who knows. Google’s approach to messaging has always baffled me. They could have had a ton of traction and market share by now if they’d have just stuck with one. Why they keep tearing them down and building another one, and why they think this latest one will do any better, I have no idea.
You can interoperate with googles RCS.
If you are willing and able to enter a partnership like Samsung, you can do it fully (including encryption support etc).Google are determined to not make it easy, and I agree with you, it appears to be yet another messaging land grab.
Trying to put myself in their headspace for a moment, one justification for making it hard is to stop thousands of apps coming out declaring “full RCS support!” through the APIs, then screwing the pooch (through poor security or deliberate back doors or or or).
Right now Google are desperately attempting to make RCS happen, after almost a decade of trying and failing to make various carriers play ball.
They do not want any bad press about how feature poor/insecure/slow/buggy it is right now.

Someone has written an open source RCS client prototype, but it has been only tested in China, where carriers do provide their own RCS servers as they are supposed. The author has not tested it with Google’s servers, which are probably blocked in China.
If you want to use SIM card based authentication, you need to have the app installed as a system app. That however is not an option for Google’s servers anyway, since they need to be able to work without carrier co-operation. Google uses SMS based authentication instead.
There does not necessarily need to be anything in Google’s servers that would reject non-Google RCS implementations: the SMS based authentication is defined in the spec, too.
Personally, I would not want the Google’s proprietary implementation to serve an API, but there to be a fully open source client instead.

So what, if RCS becomes the standard I’m going to lose the ability to choose what messaging app I use? I very much don’t like that.
To add to this, even if it were really fully open, like, say, Lemmy is, because it requires servers there’s the issue of being allowed on someone else’s server and whether servers are modified, and whether server owners want to interoperate and so on.
In some ways the RCS debacle has been similar to the Fediverse debacle about federating with Threads, or with undesirable servers. Even if the protocols are open there can still be bad actors.
This seems to imply that you need a fork of Android, if you’re to build a messaging app that uses RCS.
But my understanding is what you really need is essentially an RCS server.
Doesn’t Samsung messages use it too?
IIRC Samsung has partnered with Google and uses Google’s relay.
It’s disappointing it takes a partnership.
It is an open standard. The end-to-end encryption is not an open standard, nor are the stickers, those are both proprietary to Google Messages but the rest is open.

Yes it is, it’s been developed by the GSM Association, but Google does have de facto monopoly in the market right now by their
JioJibe virtual carrier. RCS can be freely implemented by carriers and device manufacturers independently of that, but so far only Samsung, T-Mobile USA and Verizon did so — everyone else uses Google’s Messages. Importantly, different RCS implementations can talk to each other, just like email servers, or Lemmy instances.Apple has been encouraged to enable RCS compatibility in iMessage in a loud campaign by Google, but they are obviously not very eager to do that, as their own research shows the closedness of Apple ecosystem and messaging system is a main driving factor of sales. This has been revealed in the Apple vs Epic Games case hearings
What’s that about Jio? I use Jio and Airtel and both support RCS so… I’m confused…
wait you’re right I messed up, let me edit that part out. I swear it used to say that Jio runs RCS infrastructure for Google.
edit: It was JIBE
JIBE! Yes! I remember this name!
They said Google has a monopoly using their own Jio virtual carrier. They never said Jio doesn’t support RCS.
I meant Jibe and yes I never said Jio or Jibe don’t support RCS. Quite the contrary
I might need to read up on what a virtual carrier means…
Any suggestions?
I really wouldn’t know. In this context I assume it means it is not deployed like traditional mobile networks are. The missing components being the hardware side like putting up towers etc.
I see… Well, thanks anyway 🫡
Yeah, there are links to the standard on the Wikipedia page
It may be open as concerns specs, but in most countries you’ll pay much for using provider services instead of internet.
On the other hand it’s closed, because no one except big mobile comms can offer this service. It’s better to avoid it. The only way to have free communication standards is to use the good old internet instead of the infrastructure of the provider.
No, not really
