Yes. I've never used whatsapp or telegram. I use SMS weekly or daily.

Same in Australia although American cultural bullshit tends to leak/be adopted. So the blue/green bubble probably will become a thing with our teenagers after they import it via social media.

iMessage is a very US thing

... a very US thing for people with iPhones. Which exist in a ratio of about 9:1 vs Android users, apparently.

Same here in Spain. I have not communicated over SMS with a real person for 5 years or so. Only thing I get is MFA and spam crap.
