Odd, isn't it? I live on top of a hill, and that area is just a black hole. We have coverage, but only if we don't move around the house and hop on one foot when we talk. Forget calling inside the grocery store, it's the abyss.
The pharmacist told me that only Cingular customers seem to be able to communicate in that area. When our Sprint contract is up we'll probably look at them.
Had Sprint some time ago and I am familiar with the lean a certain way, hop on one foot, face in this direction drill. I had dropped calls all the time, and worthless support from them.
Now Verizon and no problems.
