Competing wireless providers? In the US we effectively have a duopoly of AT&T and Verizon. The fall off to T-Mobile/Sprint in terms of coverage is dramatic. There may be some spots where you have 4 good choices but for many of us it's AT&T or Verizon if we want acceptable service & speeds. Both AT&T and Verizon mimic each other's pricing structures and policies. We just need to look at Sprint who is trying to offer lower prices and faster speeds yet is still losing money. The duopoly owns the most valuable chip -- coverage. The other players are at a permanent disadvantage because they can't grow with inadequate coverage nor can they address the coverage problem with poor growth.
