Have just discovered Maglobe a roaming internet service provider. They are much cheaper than AOL plus they do not charge a monthly suscription.
Maglobe are ideal for obtaining a dial up number for the internet when downroute. They use a prepaid credit system and offer about 1 hours connection for $1 in the US - and about $4-5 for the rest of the world. Visit the link below for more details.
