SMS networks that work with Cingular

Is there a list of the supported networks for SMSing with Cingular? I am
trying to send an SMS to Venezuela but so far only one of the carriers can
receive and send to Cingular (however, all of them work with AT&T Wireless).
If so, where is this list?

I found one in the cingular website but most networks that actually work are
missing (like most europeans one) but the funniest part is that four of the
ones that are on the list don't work with cingular. Go figure.
