I was in an old mine in England that was about 50M underground, i had no signal📞😫📞
4G networks are a leap forward for using phones underground, we can now stand at a subway and keep chatting, even in a tunnel! 3G was a nightmare, constant dropouts and a fear of jumping on a train😅
5G networks may provide more functionality at great depths, but i think most mine sites use walkie talkies instead of mobiles.
