All Carnival ships will be cellular "ready" by early 2007. For a current list go to
www.cingular.com click in International and in the list you will find cruise ships that are currently offering cellular service. Even though it is the cingular site.... most carriers will work on the ship. If you are going to use a lot of minutes you might want to rent a satellite phone. Minutes on cellular are 2.50/min on a rental satellite phone, I recently payed .99/ min.
