I vacation in the eastern U.P. of Michigan (Lake Huron). My Sprint cell phone is undependable. I have tried AT&T and experienced the same type service. Straight Talk (which uses Verizon) is better. Recently, I read that Straight Talk will begin using both Verizon & AT&T towers. I would like to know if signal booster amplified antenna will work. I have been unable to use Verizon broadband usb for internet (although it works across the bay). I have lots of trees that I'm sure interfere with the signal. If I place an antenna at the water edge (where there are no trees), will that give me a strong enough signal for internet & cell phone usage?
