RCI has a contract with Cingular to place cells on their ships, so you will be able to get cell service at sea, as long as the satellite is working. Your phone must be GSM-capable. If you are not a Cingular customer, the fee will be for roaming, but I don't know what they will charge. The Vision of the Seas was being installed when we sailed her in June, so I suspect that the installation is well underway fleet-wide.
