American Cruise Line and Club Med Cruises have joined the roster of cruise providers using MTN Communications for Internet and other telecommunications services at sea.

MTN also said that four existing customers have renewed their service agreements with MTN: Crystal Cruises, Moana Cruises, Paul Gauguin Cruises and Phoenix Reisen.

MTN uses satellites and land communications networks in coordination to provide vessel communication systems.

In April, MTN agreed to merge with Emerging Markets Communications. The merger is expected to close by the end of the second quarter, the companies said.
