Guessing you have whackos locally against cell towers!? We have that situation at our wealthy beach towns where they only exist on water towers.
My brother in law lives in whack job Western MA and townspeople are anti technology and have no cell reception and just got high speed internet finally on fiber in last 5 years because they fought cable TV years.
Even locally near me at Pease/NH RT95/massive truck stop a huge dead spot existed for Verizon. They finally added 5g tower and download speed on my budget plan is 300-400 Mbps from 0….so voice is clear
