Welcome to GTC Broadband

Granby Telephone Company and GTC Broadband have been serving our community with the most advanced technology since 1904.  Internet was introduced in 1995 as dial-up Internet; you remember the ee-oo ee-oo ee-oo of the dial up modems? Yet, today 100 Mbps is available in 65% of our service area.  Continuing the traditional of exceptional state of the art technology, we anticipate a full gigabit service product within the next few years.
Collectively, GTC has provided our friends and neighbors with over 100 years of experience and exceptional customer service. Call anytime to discuss our services with a local customer service representative.
GTC Broadband has been “Under Construction” placing Fiber to the Home technology in our exchange areas since 2010.  At this time, the entire Diamond exchange has been completed and Internet speeds of up to 100 Mbps are currently available.  In 2014, GTC began construction in the Granby exchange.  Presently, GTC has completed construction in and around, Ritchey, Rural North of Granby and a section in Rural South Granby.
The next phase of construction will begin soon, and will include more rural areas. Construction within the City of Granby will follow next.  Watch for our engineer teams staking and plotting the maps.
