Did you know that MMS can transmit slideshows[1]? I didn't, until my father somehow sent me one. The UI that Android has for that is — naturally — a complete afterthought. (No way to pause the slideshow, no way to navigate the slides, nothing. Just one run through the animation at Warp 8.)

In Brazil we hurry to turn off the call if it goes into voicemail, as we pay to leave a message AND nobody listens to them because it costs a lot to listen (or at least used to).
I don't know how many of the new Signal users will stay (there's already discussion in one of the new Signal groups about "Why aren't we using Telegram instead?")
Same as much of this thread - these people are not concerned much at all about encryption details, they're largely a pissed of mob of people departing WhatsApp. And some of them are already saying "there's no web client! I can't use this!!!"
I suspect I may well end up back being "the guy who's not part of most group chats" if/when they decide Signal isn't for them... And I'm OK with that.
My impression is the US/Canada are one of the only places where SMS is still frequently used for casual text communication and i'm horrified that Apple's iMessage is the one to somewhat challenge that.
iMessage is only for Apple devices.
