  This implies no encryption

    according to the article, RCS does not do e2e encryption

      RCS traffic is essentially SIP over TLS ... Which means that it is "compliant with government regulations", and with all the ensuing vulnerabilities.

  And if the sender does not support RCS? Would there be a way for an old or cheap phone to contact a new smartphone after SMS is supposedly replaced with RCS?

    I see no reason a cheap phone can't support data/rcs. My cheap nokia supports whatsapp. But I guess old cheap phones will be left out but I think no sms support will be far in the future, especially if Apple won't support it.

      Around here 2g phones have stopped working people were informed 2-3 years before it being implemented that 2g phones will no longer work. So sms being killed off is not out of the question. Majority of the people in asia got mobile phones in smartphone era where they already had a WhatsApp of similar so sms is not as big a thing as it is in North America.

      In my corner of the world at least, small $20 brickphones can be bought at practically every corner convenience store. I'm pretty sure they don't have Whatsapp. They definitely don't run android, at least.

        You can get semi smart phones with data and whatsapp for as low as 17$. See https://www.androidauthority.com/kaios-phone-review-979286/ https://www.androidauthority.com/kaios-phone-review-979286/

    It'll just send an SMS, the protocol isn't going anywhere. Phones still support 2G networks too and even iPhones can still send SMS messages although iMessage is a thing.
