my signal strength will vary from one part of town to another, where i live the signal is -103, 4,5 miles away is -75db, so it all depends on where your at, no matter what city its the area. where i used to live the signal was bad, i went to vzw and they said it was an issue with tower placement or something, so really just about each and evey area of different cities work with the cell companies i think.
