Also, passengers may now use their own cell phones from any Radisson Seven Seas vessel anywhere in the world. Guests who use their cell phones at sea should expect rates roughly equivalent to Caribbean roaming charges -- even in Europe, Asia or the South Pacific -- with billing via their existing cell phone service provider. Guests are advised to check with their cell phone providers to verify rates and to make sure that their plans offer international roaming.
