Bahrain's Batelco has signed an agreement with Telecom Italia to provide a new roaming service to vacationers travelling on cruise lines with complete voice and data coverage. The new service, 'GSM on Ship', will enable travellers on board the Costa Cruise ship fleet, the Ibero Cruise ships, and the Grandi Navi Veloci cruise line ships to receive full coverage wherever their ship goes, regardless of route or geographical location.
