Ed heard that all cellphone companies use the same towers. Does it really matter what cellphone company you go with? Leo says it isn't always the case that companies share towers, though it's not uncommon that they share the same pole. But each company has its own. So the notion is right, and it's wrong. Each company has it's own transceivers and antennas. If looking to save money, go with a mobile virtual network operator (MVNO). They buy cell services from the big five and sell it for less. But the downside is, that MVNOs won't have priority in the service. But in most cases, users will get the same service for less.
