    I know one person still using MMS, because they refuse to get a Internet capable cellphone.
    There is one phone in our family that can send them SMS, everyone else gets error messages. How is that even possible? I thought SMS are standardized.

        Fine by me, but why can’t I send them SMS?

          Missed that. Which side gets the error? The sender? Must be carrier weirdness.

          Alternatively, they opted in for RCS somewhere somehow but they don’t have an online RCS client so RCS capable senders get errors unless you explicitly set the app to send SMS only to this person
