Bringing this forward, here is my summation.
1. AOL is not really an ISP
2. UUnet doesn't offer individual accounts anymore
3. IBM/AT&T Global has poor and indifferent service with a reduced set of countries.
4. Dialing back to the USA works in some countries, but not in others. Portugal and Argentina are two examples that compress the international trunks so that modems don't work.
Has anyone tried GRIC? Any other options?
