ISA’s decision to venture into the telecommunications industry was the result of its sector diversification strategy. As a result, it moved its gained experience in transportation from one point to another through linear infrastructure, to businesses other than energy.

Due to the confidence gained with our pioneer customers in Colombia, we became a strong and powerful company, which -in just a decade- was transformed into a multinational company driving the emerging of Colombia into new markets in the region and investing in Latin America, to improve the quality of life of its people.

Our history dates back to 2001, when our commercial operations began in Colombia with an initial deployment of 1,831 km of fiber optics, serving the following cities: Medellín, Bogotá, Cali, Manizales, Pereira, Popayan, Tunja, Bucaramanga, Barranquilla, Sincelejo, Monteria, Riohacha, Santa Marta and Valledupar.

In 2003, we landed in Ecuador, through a partnership with the local network TRANSELECTRIC, which led to TRASNEXA S.A. In the last 5 years of the first decade of the XXI century, we began commercial business in Peru, where we energized a completely concentrated market, we offered an alternate option of land-based telecommunications towards Caracas, through an agreement with CANTV, and we began local operations in Chile, one of the strongest and most admired markets in the world where we are proud to be the only company with an open business model. During the second decade of the XXI century, we are heading towards opening markets in Argentina, Brazil and Central America, delivering the promise to operate the largest terrestrial telecommunications network in the continent.
