Sex chat only sms
Sabharwal estimates that 8 trillion SMS-based messages are sent every year.
It’s the universal, default option; every phone supports it, and it always works.
And Duo, Google’s new-ish video chat app, is actually surprisingly successful; a quarter of Duo calls are to or from an i Phone.
But it’s primarily a video chat app, which leaves Allo and Android Messages: two apps that, from a “consumer product” perspective, do essentially the same thing. Even though Samsung phones don’t use Android Messages as the default SMS app, most of the other major manufacturers do (outside of China, anyway). “They’re not interested in going to a different place to use SMS.” People, even in 2018, tend to just use the default app.
Samsung phones will also support Chat using Samsung’s app.
You will still be able to download Google’s app if you’d prefer to use it, though it seems unlikely that third-party developers will be able to create full RCS-enabled apps.
