The only large group of people who still primarily use SMS to communicate person-to-person is Android users in the USA.
Every other country has settled on either Telegram, WeChat, WhatsApp or FB Messenger, or other niche apps. These apps work on both iOS and Android and often also Windows. I haven't sent an SMS in probably 12 years. I don't know anyone who has.
It's only in the US that iMessage is so prevalent that Android users have to use SMS, the only other way of messaging iOS devices. And the US is quickly becoming a de-facto iOS only country. It already has more than 50% market share, even 80% among young people.
With the US going (almost) full iMessage and the rest of the world having already settled on another app there simply no point to supporting SMS.

SMS decline is probably inevitable though.
> The average mobile connection sent 51 messages per month in 2020, 17 fewer than in 2019.
I'd love to know the median, I assume there's a number of power users that drives up the average. Or bots that are sending out thousands of messages a day.
Wow, it's really dead.
Apparently Germany has ~8bn SMS for 160m contracts (don't ask me why there's an average of two contracts per person), which is like 50 a year. Edit: that number seems to include automated messages.
That seems reasonable: Company-issued phones, LTE-Routers, some undercounting of M2M, and gerneral churn (I changed provider so I had 2 SIM-cards this year).
