RCS is quite terrible. Very few carriers still host RCS services. The only reason it works is because Google decided “fuck it, if you guys won’t provide RCS, we’ll just set up our own server for everyone to use”.

My country has a total of 0 carriers that run RCS servers. Only Vodafone had them, and they shut them down, because nobody used them. Everyone who uses RCS here uses Google’s servers. Wikipedia still lists carriers that have shut down RCS services so even the limited list of RCS capable carriers looks bigger than it is in reality.

I don’t know how Apple will implement RCS, but if they use carrier services (which, by the way, often are rented from Google as well), there’s a good chance RCS still won’t work. The only reliable way for Apple to add RCS is to copy what Google did and host an RCS server themselves.

I’m glad Apple is finally adding support, but I don’t blame them given how absolutely terrible the uptake among carriers was.

Honestly, I’d rather have Apple open up iMessage than for them to enable RCS, but regulatory pressure from China has made them include RCS anyway, so they might as well support it in the rest of the world.

To be fair, this is only a problem in countries where texting never died. In a lot of countries, apps like WhatsApp have taken over the role of the standard messenger over a decade ago, and everyone has one or more messaging apps they actually use.

The funny thing about RCS is that it’s not encrypted, and is designed to be run in carrier networks, where law enforcement agencies can read every message sent back and forth. If RCS had been taken up rather than WhatsApp or Line or any other competitor, our privacy situation would actually be much worse. In a way, I’m kind of thankful for RCS being so terrible.
