In my working years we were on the road all the time way back off the beaten paths working on COMMS SITES...
VERIZON was the only carrier we could use...
They are indeed spendy haha... They problem is they know they are spendy...
AT&T is catching up somewhat however... I keep getting brochures about their using the DIRECTV network to give us downstreaming of SAT TV CHANNELS. No Dish Needed just use the internet and a big data plan... AT&T is now working here at the house pretty good. It was always real bad before. I always told everybody here with their AT&T cell phones they would have to do the GREEN ACRES thing --- go outside and climb a telephone to make their contacts hehe...
One of my kids is now using AT&T and it works here at the house about the same as VERIZON does...
