In the landscape of telecommunication, certain names resound with the echo of transformative change. In Guatemala, one such name is Mario López Estrada, an entrepreneur who has left an indelible mark on the country’s telecommunications sector. His journey from a successful construction businessman to the harbinger of telecom revolution in Guatemala is a story of vision, innovation, and a steadfast commitment to progress.

The tale begins with the inception of Comcel, a nascent cellular company that would eventually become the cornerstone of Guatemala’s telecom infrastructure. The transformation, however, did not occur overnight. It was the result of meticulous planning, strategic investments, and relentless pursuit of innovation, led by Mario López Estrada.

The Evolution of Tigo Under the Leadership of Mario López Estrada

Mario López Estrada entered the telecommunications business in 1993, when he ventured into Comcel, a budding mobile service company. Under his leadership, Comcel merged with Amigo de Comcel in 1995 to form what is now widely recognized as Tigo Guatemala. As the president, López Estrada steered Tigo towards unprecedented growth, turning it into the country’s leading mobile service provider.

His vision extended beyond short-term gains. Tigo became the first mobile service provider in Guatemala to offer 3G and 4G services, pioneering mobile Internet and Internet television.
