A subsidiary of Range Telephone Cooperative, Inc.

Advanced Communications Technology (ACT) is part of a larger group of companies, owned by Range Telephone Cooperative. Range was established in 1953 and serves 16 telephone exchanges and over 8,000 access lines throughout South East Montana and North East Wyoming.

Necessitated by changes in the telecommunications industry, as well as the addition of several competitive products and services being offered by the Range family companies, ACT was formed and incorporated on April 23, 1997. Originally located at the Range headquarters in Forsyth, MT, ACT was focused primarily on offering competitive services within the Range, DTE and RT serving areas. These original services included products such as long distance, business telephone systems and dial-up internet. As the business continued to grow and the telecommunications industry continued to change, the Range family saw a need for greater capacity in the network, specifically in Central and Northern Wyoming where sufficient transport facilities were lacking. It was at that time, the Range family constructed a sizable fiber optic network, spanning from Worland to Casper and north to Gillette, Buffalo, Sheridan and into the Montana fiber network, Vision Net. Today, this network continues to expand, with connections to South Dakota Network (SDN), as well as a route over Togwatee pass to meet another Wyoming independent telephone company and ultimately tie into the Idaho fiber network, Syringa.

In 2001, ACT established a CLEC (Competitive Local Exchange Carrier) in Sheridan, WY. Operating as a non-regulated service provider, ACT offers a full suite of state-of-the-art communications services, including Broadband, Optical Ethernet, Primary Rate Services (PRI), voice solutions as well as a host of new custom calling features. A sizeable fiber optic network has been being built and continues to expand in Sheridan and Buffalo, to serve customers with voice and high speed Broadband service.
