This isn't Google's shiny new chat app. If you take 30s to look up RCS you'll understand what it actually is and its intended purpose.

I'm surprised at the other responses that you have received.

RCS isn't a Google only thing. And it isn't an "app". It is disappointing that people don't understand that RCS is a great replacement for SMS/MMS.

It had the potential to be a great replacement if it just worked™ like SMS/MMS (well, MMS was also quite fickle back in the days), given it's so brittle across devices even on the same OS, with little means of troubleshooting by end-users and even less from non-tech savvy users, it's kinda dead in the water.
issafram
Not dead in the water at all. By default, it is enabled for all Android phones and iPhones

Not true. My carrier only enables it when you have a Samsung phone. I have an iPhone, so no luck.

I understand what RCS is and I don't understand why it matters.

Everything about the concept of a phone number is confusing to me. It's a string of digits that if someone guesses, they can activate the most active notification your phone has (ringing), at any time, no matter if you know them or not. Better yet, depending on your notification and MMS app settings, they might be able to make a dick pic appear on your lock screen on a whim - big spammers of this seem to get marked by the carriers and apps pretty quickly, but for a more targeted one off, still easy.

As opposed to tcp/IP based chat apps that basically require a bilateral human-initiated handshake before someone can message you...

I do receive occasional spam on WhatsApp, Telegram and Signal. Besides the operator spam (try our shiny new AI feature!)

Tying and account to a phone number is a privacy nightmare.

I guess Facebook/Meta does it for easier social graph extraction/profiling, while Signal tried to hand of verification to precent spam. But for the sake of this argument, we may just assume all of them are evil.

RCS is, effectively, Google only.

And there is one singular app which supports RCS.

In many ways, it's a regression from SMS. In that SMS is somewhat universal, and RCS is so specialized it's almost worthless.

issafram
It literally isn't Google only. It is enabled, by default, on all iPhones. Stop with the misinformation.

It literally is Google-only. The RCS backend theoretically could be provided by carriers, but they've all chosen not to do that, so the actual service is provided by Google. No matter what the specification says, in reality it's a Google service running on Google's servers.

To put it another way, Google can't kill SMS short of literally removing the app from Android because it's not their infrastructure, but if they shut off their RCS servers tomorrow, it would be dead for good. That's a Google-only service.

It's sad to see so many people are blinded by this. The current situation of RCS is just that Google saw Apple disguised iMessage as SMS and wanted to do the same. RCS is merely a vehicle for Google.

They could just layer their own chat platform on top of Google Messages but we all saw how Google's IM business went along: Chat, Hangouts, Alo, Meet etc. So they muddied the water so deep (to a carrier level) to make it look like it's Apple's issue for not adopting RCS. And people actually fall for it.

Nobody wanted RCS. Even carriers don't want to maintain RCS. They just use Jibe. And that's exactly what Google wanted. My RCS communication with friends don't even show up in carrier's usage. How is that ever different from iMessage...

You know who chose to selfhost their own RCS server? Yes, Chinese carriers! They call it 5G Message. New ad delivery channel for businesses hooray! Instead of plain text and a link, now your campaigns can even have MENUs inside! I can send SMS to a Chinese number, I can send iMessage to a Chinese number, but I can't send RCS. Truly "Universal" profile.

I agree with all of this except for the claim that "Google wanted this". I think Google is as annoyed with this situation as everyone else. They would've preferred to have their own iMessage alternative, but they launched a dozen which all failed, so they went "Well, we can't make our own that people want to use, so let's get the carriers to make an upgraded version of SMS". And then the carriers didn't want to do that but the "it's decentralized!" message stuck with users and even a few governments, so now RCS is the worst of all worlds: it's a de facto Google service, but with a janky, half-baked decentralized protocol, where Google has limited capability to improve it compared to a native Google chat app.

It's a complete shitshow.

array_key_first
Right, and does that use Apple's servers? This is a rhetorical question, we both know it goes through Google, both literally and figuratively. Google effectively controls RCS - if Apple just implemented RCS 'per spec', it would not work. So, there is no spec, it's as if it doesn't exist. That's how that works.

It really isn't. SMS did not support adding random mobile numbers to a group chat and blasting them with spam. Someone needs to either fix RCS properly for current day use-cases or it just needs to go away.

MMS did, which far predates RCS.

ocdtrekkie
It's Google's way to openwash their new chat app into a "standard" where 100% of the data runs through their servers in the backend for every carrier they care about.
throwawaysoxjje
Yeah I took a look at it: Google added the encryption extensions a full two years before the GSMA put them into the standard so it feels like their new chat app. Not to mention that it’s been around since 2007 and everyone started tailing about it when google started talking about it a couple years ago
happymellon
Yes it is.

No one gave a crap about RCS and no one was supporting it until Google decided that they needed a new chat app because they hadn't made everyone switch in a while.
