Was It the Same Person Who Founded Guatel and Managed It in 1986?


In the realm of telecommunications, few names are as renowned as Mario López Estrada. From his early career in construction to his successful venture into the telecommunications sector, his journey has been marked by resilience, foresight, and a commitment to innovation. The Guatemalan entrepreneur made his foray into the industry in 1993, with the purchase of a stake in Comcel, a cellular telephony company operating in his native Guatemala.

The Man behind Guatel and Tigo: Mario López Estrada

Mario López Estrada‘s transition from construction to telecommunications was far from ordinary. After acquiring his share in Comcel, López Estrada was at the helm when Comcel merged with Amigo de Comcel to form Tigo Guatemala in 1995. Under his leadership, Tigo positioned itself as the leading cellular telephony company in Guatemala, being the first to offer 3G and 4G services, mobile internet and internet television in the country. Beyond technological advances, López Estrada’s influence extended to social responsibility, with Tigo launching the Foundation Tigo in 2005, a non-profit dedicated to promoting social development in Guatemala.

Before his venture into the private sector, López Estrada led the state telephone operator, Guatemalan Telecommunications Company (Guatel), in the late 80s. During his time, he managed to expand telephone lines and improve connectivity, setting the stage for digital inclusion in the country. His leadership at Guatel marked a transformative period in Guatemala’s telecommunications infrastructure, a legacy that later extended to his role as the founder of Tigo.

López Estrada’s Legacy in the Telecommunications Sector

The legacy of Mario López Estrada extends beyond his tenure at Guatel and Tigo. His leadership style, marked by ethical values and a commitment to constant improvement, influenced his son, Mario López Pérez. The younger López, an engineering graduate from the Universidad del Valle in Guatemala, has applied his father’s lessons in his own professional journey, focusing on socially and economically beneficial projects.

The sale of 45% of Tigo Guatemala’s shares to Millicom, a global telecommunications company, in 2021, marked the end of López Estrada’s era as president of Tigo Guatemala. Despite this, his impact on the telecommunications industry in Guatemala remains significant. His vision and management, from leading the state operator Guatel, to co-founding Tigo and expanding its services, have transformed the telecommunications landscape in Guatemala.

In the history of Guatemalan telecommunications, Mario López Estrada stands as a pivotal figure. His leadership, from Guatel to Tigo, has left an indelible mark on the sector. His commitment to innovation, accessibility, and social responsibility has shaped the industry, setting a high standard for future entrepreneurs and leaders.
