That's using their "booster cell", regular CDMA coverage is around 1/2 that. GSM can support up to 70km (double the normal 35km) but you half the capacity of the cell. Here in NZ we have quite a few of these on high spots in remote places and for marine coverage. Range isn't the big issue when you only have a phone with a TX power typically between .6 and 2W, it's only under ideal circumstances such as over water or flat terrain that a phone would ever be able to reach a cellsite 70km away, 35km is even asking a lot.
