Micro you have to remember the size difference between Israel and the US and the fact that our infrastructure is becoming more and more incapable of meeting the demands being placed upon it.
A lot of it is that infrastructure in the US is also far less competitive.
For example, it is legal where I sit for the major phone provider to also own a cable company, and for the other major cable company to also provide phone service - so anywhere you can get cable and phone lines, the cable company can sell you phone service, and the phone company can sell you cable TV (enabling the two to compete with each other, driving down prices). ^There are also secondary providers.
They've also licensed something like five cellphone companies (i.e. providers with their own towers and infrastructure), and God only knows how many 'virtual providers' (which buy service from the major providers and re-sell it), which means you can get all sort of weird cell services.
The low population density matters less than you think unless you actually live in the low-density areas yourself. It being difficult to bring good infrastructure out to the desert doesn't mean you can't have good infrastructure in a city or a suburb.
