SMS was ubiquitous in the United States long before smartphones. We didn’t have country codes to worry about, so anyone else in the United States was reachable in near real time over text, using an asynchronous, open, inter-carrier method of communication. If I had your phone number I could text you for free. Layered onto that was various automated systems over text (alerts, etc.). Later on, the carriers rolled out MMS for basic pictures being sent, group texts, etc.
So when iPhones became popular here, the default method of communication was SMS/MMS. The iPhone user knew that it would work with dumb phones, Android phones, Windows phones, whatever. And those habits and those chat threads predated the rise of WhatsApp, FB Messenger, WeChat, Telegram, etc., and a lot of those apps simply didn’t work with old dumb phones. Why give up an existing group chat thread just because one of those friends didn’t have a smartphone yet?
Then, whenever every member of a chat had an iPhone, the system automatically defaulted to the upgraded iMessage experience: high quality media sharing, typing/delivery/read notifications, reactions, etc. It was a slow transition, and didn’t start to show clear advantage over the open SMS/MMS standard until smartphones were ubiquitous, and where most people had iPhones.
And so once everyone had a “it just works” app, they didn’t want to switch to an app that required everyone to get a separate account and download a separate app. Especially because the iPhone hit something like 80% market share among certain demographics (the young, the non-technical rich, etc.).
There’s some history here:
