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.
As far as I understand it, there is an API but as with all APIs you need a key/license/magic number to use it.
So far, Google has allowed access to Samsung, a carrier version and no one else.
I assumed you'd have to interface with Google to get messages to/from other RCS users using their app, but does that not happen via a bridge-server?
