I think the Canucks (sp?) would probably take offense at the "North
America" classification! :-)

Not at all. "North America" is merely a geographical designation. Their
trade and economies are very closely linked in many ways, including
their cellphone services.

And includes Mexico as well, which doesn't link its cellphone
services.

I think that with "very closely linked in many ways, including their
cellphone services", Mike meant that "North America" uses the same
cellphone technology/frequency.

You seem to imply that Mexico doesn't use the same cellphone
technology/frequency, but at least one Mexican network - the only one I
'happen' to know - *does* use the same technology/frequency (GSM 1900),
Telcel [1].

I happen to know this, because Telcel is AT&T's partner network for
roaming in Mexico with AT&T's GoPhone service. I.e. GoPhone can *only*
roam in Mexico and *only* on Telcel's network.

It seems [2] that the other Mexican networks are also "North America"
style, i.e. GSM 1900 and 3G 850.
