No one is using iMessage outside of the USA is like no one is using microsoft Zune. It’s not literally no one but due to the network effect people use Whatsapp or whatever is popular in their country(some places use facebook messenger, Line, Viber, Skype, WeChat etc and you are expected to have it. Why switch apps all the time when you do the exactly same thing everywhere? Except for switching away from iMessage of course because %70 of the people won’t have it even if they want to).
