DoCoMo Pacific is a wholly owned subsidiary of predominant mobile phone operator in Japan, NTT DoCoMo. With combined offerings to include the latest mobile services, television, internet and telephone services, DoCoMo Pacific is the largest provider of telecommunications and entertainment services serving Guam and the Northern Mariana Islands, as well as the military installations in the area.
Headquartered in Tamuning, Guam, DoCoMo Pacific was originally a merger of Guamcell Communications and HafaTel. It was acquired in December 2006 by NTT DoCoMo, a spin-off of Japanese communication company Nippon Telegraph and Telephone. The acquisition allowed NTT DoCoMo the opportunity to share its technology with the region as including significant investments and upgrades in DoCoMo Pacific.
In October 2008, DoCoMo Pacific was first on Guam to introduce the fastest and only 3.5G network. In November 2011, DoCoMo Pacific launched 4G HSPA+ service on Guam followed by the launch of advanced 4G LTE service in October 2012.
On May 22, 2013, DoCoMo Pacific acquired MCV Broadband (full name Marianas Cable Vision Broadband) from Seaport Capital, an investment company based in New York City. Seaport acquired MCV in 2005, adding it to its portfolio of cable companies that Seaport had an ownership stake in, including Everest Cable, MetroCast Cablevision, Mid-Missouri Telephone Company and Otelco Holdings.
