I'm in the US, have android and use sms a lot, almost entirely to communicate with users of "dumb phones".

In fact, all the ios users I communicate with do it over whatsapp or telegram.

Today I had an ios user sms me asking if he could send me a voice message. I honestly have no idea if that would have worked but I directed him to whatsapp (that he already had installed) and it was frictionless thereafter. I expect I'll never see another sms from him again.
