Are we talking children or teenagers?
What's frequently missed is that most organization of meet-ups, birthday parties, talking to romantic interests, going to concerts et al, all happens on social media and in group chats now, and has done for the best part of fifteen years in the West. For the prior generation, if you aren't online, you aren't cool, and you won't know about cool things that are happening.
The current generation seems to have a fascination with dumb phones and eschewing tech obsession if the media spin is to be believed versus the numbers on social media apps. Both can be valid things that are occurring though, but I'm willing to bet that the dumb phone movement is a small one or a LARP for elitist cool points.
