New EU rules mean WhatsApp and Messenger must be interoperable with other chat apps. Here’s how that will work.

WhatsApp will soon make it possible to chat with people who use other messaging apps. It’s revealed some more details on how that will work.

— Apps will need to sign an agreement with Meta, then connect to its servers.

— Meta wants people to use the Signal Protocol, but also says other encryption protocols can be used if they can meet WhatsApp’s standards

— WhatsApp has been testing with Matrix in recent months, although nothing is agreed yet. Swiss app Threema says it won’t become interoperable

    I wonder what’ll come first, this or RCS on iOS?

    group chats will come years down the line

    Oh come on. (Though that’s fair enough, since coordinating groups including users from different services is likely a lot harder to get right.)

        From what I understand, it’s implemented on mobile carrier level, so any phone or other device with a cellular modem connected to a carrier that supports it should be able to use it (edit: of course, ignoring insufficient access, at the very least rooted Android or some Linux should work). Can’t really find more specific details right now though. Here’s a library and sample client for it though: https://github.com/Hirohumi/rust-rcs-client

        Of course, this is only for clients, it’s true you can’t set up your own server.

          It’s like with SMS, needs communication of the OS to the modem to the carrier’s server. And just like with anything carrier related the progress is very slow, no mobile phone even supports it (for now only Android with Google’s own app that connects to proxy to bypass the modem) and… is my opinion unnessesary.
