About IT&E

Formerly Micronesian Telecommunications Corp, IT&E was a part of Verizon International. CITADEL acquired IT&E in 2005 after successfully navigating the US CIFUS process and the Federal Communications Commission. In 2006, a partnership was established with Sumitomo Corporation, one of Japan's largest trading houses, which invested in the company as part of its telecommunications push. The company acquired IT&E in Guam, and together, became the largest wireless provider in Micronesia. The entire company was renamed IT&E. IT&E was the first in the region to offer 3G services with the launch of CDMA EVDO in 2009. It soon followed with the launch of 4G LTE in 2011.
