Are there any apps that support RCS that aren’t made by Google or a crappy cellular provider (ie: bloatware Verizon apps)?
I appreciate the features RCS has, but I’d love to get that without sending it all to Google with a “trust us” approach to backdoor keys. The documentation I looked at indicated that anyone could setup an app to support RCS and communicate with Google’s RCS users, but I can’t find any apps that actually do that.
Also would love to be able to message from multiple devices using RCS, which Google has working in their web app.
RCS is all about controlling the messaging market — just like every other messaging network out there. Every implementation is proprietary and locked behind the implementer’s servers.
If you want something open source you want Signal. There are also other messaging solutions that you can self-host.
Big tech will never give you open access to their networks because that’s against the whole point.
SMS is the odd one out because it doesn’t require servers, and the reason it’s so open and universally supported is because back in the day the governments of France and Germany forced carriers to do it that way, and once it got popular it spread.
