Sea & Air: Roaming via satellite connection
Cruise ships and planes sometimes provide coverage via mobile networks. These networks are often run over satellite connections, although the hardware displays the name of a regular mobile phone provider, such as Vodafone Malta. Satellite connections are always more expensive than regular mobile phone connections.
