    SMS can have end to end encryption

    in theory it can, but in practice i’m not aware of any software anyone uses today which does that. (are you? which?)

    TextSecure, the predecessor to Signal, did actually originally use SMS to transport OTR-encrypted messages, but it stopped doing that and switched to requiring a data connection and using Amazon Web Services as an intermediary long ago (before it was merged with their calling app RedPhone and renamed to Signal).

    edit: i forgot, there was also an SMS-encrypting fork of TextSecure called SMSSecure, later renamed Silence. It hasn’t been updated in 5 (on github) or 6 (on f-droid) years but maybe it still works? 🤷

      I was thinking of RCS security apparently, but was mainly talking about what’s theoretically possible.

      There’s nothing stopping someone creating a E2E encrypted SMS app. The medium doesn’t matter, only the data. You could have end to end encrypted carrier pigeons if you want.
