I guess what I am getting from this thread is, there is 3G service out there in the wild. However, in locations where 4G and 5G is available, 3G has been phased out

This doesn’t jibe with my experience trying to make phone calls on rural highways, where it seems there is no signal whatsoever more often than not.

I suppose this could be because ATT-Verizon-T-Mobile used to have 2G in that area (which was discontinued — 900Mhz analog voice band, also decommissioned) has moved on and left swathes of the US without signal, whereas, certain areas (commenter omits an example) never were served by major telecoms and have “evolved” their tech more slowly, so 3G is not decommissioned in those places. In that sense yes there is no contradiction. It still feels like we’ve gone backwards since there are places I used to be able to make a phone call that are now considered remote area with satellite SOS being you’re only way to reach someone
