SMS doesn’t handle pictures, videos, gifs, reactions, or group conversations. Things I use all the time. MMS handles some of that, but implementation varies greatly by carrier and device. If you want consistency of that functionality, you have to go with an app. Apple and Google have created replacements for SMS and MMS that could be the next version of “texting” but Apple refuses to let anyone else use theirs (iMessage) and Google has only half opened up theirs (RCS), so those don’t really fix much.
Right. Like, my use case for SD cards is for my cameras. I want to take pictures and bring them home across international borders. And a 4TB card would be amazing, though probably not fast enough. I simply don’t put files that I don’t want people to find onto my SD cards in the first place.
