Really appreciate the reply - thank you. It's always intriguing to see how the other half lives, as it were.

MMS never seemed to catch on in the UK and never seems to be included in the free allowances which probably doesn't help (eg I have unlimited calls, sms, >100gb data but MMS still costs me 50p each). I think the only time I've seen it used in years is very occasionally when I ask an iPhone user to send me a photo and they don't realise I'm on Android and won't automatically have it funnelled via Apple, so instead I get badly compressed unreadable photos of printed letters.

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.
