In Europe not only Android is dominant but people use WhatsApp or Messenger. iPhone owners must use them too as their primary messaging app. I guess they have their iMessage full with SMS from banks and other notifications, like my Android SMS app.
Yes Or mms or rcs. Sometimes you could be texting another person on an Android that's just on a different carrier and for whatever reason you can't get the rcs status. And this applies to way more than just texting... Some carriers let calls that stay within their own network sound way better. Switch sims and boom, crap quality.
I use whatever The other person wants to use though. Telegram, discord, Skype, email, text, Twitter, whatever
