I live in slovenia, and have instagram, whatsapp, viber and telegram for "normal people" who only have one of those (and can't be reached elsewhere), I can't reach some people (besides sms/call),because I don't have facebook (messenger). Also i have a few relatives using skype only, those are a pain, because the client sucks.
