I don’t think cell tower networks would be because they are probably on wifi when calling(at home) and likely use something like facetime or your choice of free open source messenger which uses the internet.
I used to work next to a huge arena. Every time there was a sold-out show, the cell service would be rough the whole time from people sending videos and such. When the shows let out it would be a complete meltdown while people tried to get Ubers.
I remember my graduation used wireless(presumably bluetooth) speakers, and they were constantly cutting out almost the whole time. Not quite to the scale you’re talking about but the graduation hall was packed and I’m sure it was full of phones and smartwatches.
