This kind of argument always confuses me a little. Sure, the total cost of the network in the UK probably costs less than the US, but that doesn't take into account the amount of customers, either. The US may have to have a bigger network to cover the entire area, but the US also probably has a lot more customers, too. So I think a better comparison is cost of network per capita rather than total cost.
Thinking that it is the wrong argument also happens to be self-serving in that it supports your view that where you live is somehow superior in this respect. The fact is, national carriers in America have to run a lot of network cable and erect a lot of network towers in areas were very very few people live just in order to cover one of their customers if they happen to travel that far.
The fact is, the landmass is a far more important question then the number of citizens.
Imagine this metaphor: one area has 100 cell phone users packed into a single household. Another area has 100 cell phone users in an area the size of London. Which one of those two networks do you think will cost more for a carrier to support?

Fair enough, but my point was that the amount of land isn't the only factor when upgrading.
That was your point? Why? Nobody here was arguing that the number of users has nothing to do with the cost of the network. We were talking about the reason why a typical USA cell phone plan costs more than a typical European cell phone plan. Have you ever wondered why a typical European plan costs so much more than a typical African plan?
In case you have not, here is a lesson for you: the cost of cell phone plans takes into account many different variables. These variables include the number of users, the size of the area that the carrier has to cover, the general level of income that the target market has, and the amount of competition in the market.
When all of these variables come together in the soup that is the cell phone provider markets, the USA ends up with the highest cell phone plans. But let's not get too proud when bragging about how cheap European cell phone plans are, because your cell phone plans make most of the rest of the world's look pretty expensive also. The USA also moved much more quickly than Europe to LTE service, so you were getting poorer coverage as well.
