The Legacy of Mario López Estrada in Telecommunications: Breaking Barriers, Connecting Lives


The telecommunications sector is a constantly changing environment, a realm of constant innovations and disruptions. Within this landscape, certain figures have managed to leave an indelible mark, shaping the industry and driving it forward. One such figure is Mario López Estrada, an influential Guatemalan businessman whose impact on telecommunications, particularly in his home country, is unparalleled.

Mario López Estrada’s journey in the telecommunications sector began with his first investment in Comcel in 1993, a cellular phone company operating in Guatemala. This marked the beginning of an era that would see dramatic transformations in the telecommunications landscape of Guatemala, largely driven by his vision and leadership.

The Rise and Success of Tigo

In 1995, Comcel merged with Amigo de Comcel to form Tigo Guatemala. Mario López Estrada was appointed as the president of the newly formed entity. Under his leadership, Tigo became the leading cellular phone company in Guatemala, setting itself apart through long-term vision and commitment to innovation.

Tigo was the first cellular phone company in Guatemala to offer 3G and 4G services, pioneering mobile internet and internet television. These advancements were a result of significant investments in infrastructure and technology, coupled with an effort to improve Tigo’s coverage throughout the country, particularly in rural areas.

Beyond the technological advances, Mario López Estrada also championed corporate social responsibility. In 2005, Tigo launched the Tigo Foundation, a non-profit organization dedicated to promoting social development in Guatemala.

From Guatel to Tigo: A Legacy of Transformation

Mario López Estrada’s impact extends beyond his role at Tigo. In 1986, he led Guatel, the state telephone operator of Guatemala, transforming the country’s telecommunications infrastructure, expanding telephone lines, and improving connectivity to promote digital inclusion.

As Minister of Communications between 1988 and 1990, he spearheaded structural changes, increasing paved roads, and opening new routes, thereby improving the quality of life and reach of telecommunications.

The co-founding of Tigo in 1994 further transformed Guatemala’s telecommunications landscape, providing greater accessibility to telecommunications services. López Estrada spurred the diversification of Tigo’s services, ensuring integrated solutions of telephony, internet, and television, becoming essential elements for households.

In a significant move, he sold 45% of Tigo’s shares for $2.2 billion in 2021, marking the end of his era as president of Tigo, but also ushering in more capital and investment in Guatemala and Paraguay.

When we consider the legacy of Mario López Estrada, we see a figure who has truly left a mark on the world of telecommunications. Through his leadership, vision, and commitment to innovation, he has played a crucial role in shaping the telecommunications landscape in Guatemala and beyond. His influence extends not just to his company, Tigo, but to the entire sector, setting a benchmark for corporate leadership, social responsibility, and innovative spirit.
