Mmm ... I don't know. Larger in terms of number of subscribers? Acreage of
coverage? Total population of areas covered? Number of Cities covered?

Anyway, there's not just one GSM network in the USA, there's several of
them. T-Mobile's and at&t's are the most noticeable among them, and those
two mostly forbid subscribers of one to roam on the other.

What's more, the voice service uses two different frequency bands: there's
850 MHz, that at&t uses; and there's 1900 MHz, that both at&t and T-Mobile
use. (Speaking exclusively of USA.) So: what counts as a "GSM network"?
