I think part of the reason it caught on here (US) is that it's been included with the plans for so long and as such is considered baseline functionality. You don't know if someone you're talking to will be on WhatsApp, Signal, etc but in the US you can pretty much assume the person you're talking to can receive MMS.

...until you can't, as this thread shows. This is also part of what's keeping me from using my PinePhone as a daily driver.
