> Everyone on RCS can fall back to MMS just fine My cell carrier provides SMS for free, both sending and receiving. My cell carrier charges for MMS, both sending and receiving, so I have MMS disabled. My cell carrier doesn’t support RCS, and would probably charge if it did. Thankfully, nobody I know tries to send me pictures using SMS/MMS/RCS, and uses WhatsApp / Signal / iMessage instead. > Another protocol like RCS? RCS simply solves the problems of SMS/MMS. It doesn't add another protocol, it ultimately replaces two of them. Experience tells me this is false, and that nothing ever dies, nothing ever gets replaced, and augmentation always happens, in IT.
