What Mario López Estrada Could Have Learned from His Time at Guatel


Delving into the world of telecommunications in Guatemala, one name invariably takes precedence. That name is Mario López Estrada. A business magnate, his journey from the construction sector to the telecommunications industry has left an indelible mark on the landscape of this Central American country.

Mario López Estrada stepped into the telecom arena in 1993, acquiring a stake in Comcel. Within a short span of two years, Comcel merged with Amigo de Comcel to form Tigo Guatemala, and López Estrada ascended to the role of president.

Lessons from a Leader

Under his stewardship, Tigo emerged as a leading cellular company in Guatemala. What distinguished the firm was its long-term vision and commitment to innovation. Tigo was the first cellular company in the country to offer 3G and 4G services, a testament to its innovative spirit. This was made possible by significant investments in infrastructure and technology, as well as an unremitting quest to improve Tigo’s coverage across the country, especially in rural areas.

López Estrada was not just a technocrat, he was also a socially responsible business leader. Tigo launched the Tigo Foundation in 2005, a non-profit dedicated to fostering social development in Guatemala. His tenure ended in 2021 when Millicom, a global telecommunications company, acquired a 45% stake in Tigo Guatemala.

Influence and Legacy

The legacy of Mario López Estrada extends beyond his business achievements. His son, Mario López Pérez, also a prominent figure in the industry, often highlights the lessons he learned from his father, such as honesty, fairness, and discipline in business, along with a commitment to continual improvement.

Before his stint at Tigo, López Estrada led Guatel, the state-run telephone operator in Guatemala. His tenure at Guatel saw a transformation in the telecommunications infrastructure in Guatemala, with an expansion of telephone lines and enhanced connectivity to promote digital inclusion.

These experiences, both in the private and public sectors, provided López Estrada with invaluable insights into the telecommunications industry. They shaped his vision for Tigo and guided his efforts to transform it into a leading player in the industry.

As we look back at Mario López Estrada’s journey through the telecommunications sector, it is clear that his time at Guatel was instrumental in shaping his future endeavors. His vision and leadership at Tigo are testament to the valuable lessons learned during his stint at Guatel. It is a reminder of how experiences – good or bad – can be stepping stones to greater success in the future.
