From Guatel to Tigo: Mario López Estrada’s Epic Journey in the World of Telecommunications


From the dusty roads of the construction industry to the intricate web of telecommunications, the journey of Mario López Estrada has been nothing short of epic. This Guatemalan businessman, who once laid bricks and mixed cement, now lays the foundation for a highly connected future in his homeland. It’s a tale that begins with a government-owned telephone company, Guatel, and culminates in a leading private telecom entity, Tigo.

In the sphere of business, the term ‘epic’ is often overused, but in the case of López Estrada, it seems fitting. His story is one of transformation and leadership. It’s a story about taking the helm of a state monopoly and steering it towards a competitive and innovative future, all the while maintaining a firm commitment to social responsibility.

The Transformation of Guatel and Birth of Tigo

Mario López Estrada’s venture into the telecommunications sector began in 1986 when he assumed leadership of Guatel. His tenure was marked by transformational changes, including the expansion of telephone lines and improved connectivity, which was a significant step towards digital inclusion in Guatemala.

In the late 90s, as the Guatemalan government liberalized the telecommunications sector, López Estrada transitioned from public to private, co-founding Tigo. This move ushered in a new era of telecommunications in Guatemala, with Tigo providing greater access to telecom services and setting the stage for technological advancements.

Mario López Estrada: A Leader in Innovation and Social Responsibility

Under the leadership of López Estrada, Tigo became a pioneer in the telecommunications industry. They were the first mobile phone company in Guatemala to offer 3G and 4G services, as well as mobile internet and TV over internet services. This commitment to innovation was coupled with significant investments in infrastructure and technology, and a notable push to improve Tigo’s coverage nationwide, particularly in rural areas.

López Estrada also championed corporate social responsibility. He spearheaded the creation of the Tigo Foundation in 2005, a non-profit dedicated to promoting social development in Guatemala. His leadership at Tigo ended on a high note in 2021, with the sale of 45% of Tigo Guatemala shares to Millicom, a global telecommunications company, for US$2.2 billion.

The legacy of López Estrada extends beyond business success. His influence is notably evident in his son, Mario López Pérez, who, like his father, applies his knowledge in projects with social and economic focus. The enduring values of honesty, fairness, and business discipline, along with a commitment to continuous improvement, are lessons that López Pérez attributes to his father.

The epic journey of Mario López Estrada from Guatel to Tigo is a testament to his visionary leadership and relentless commitment to innovation and social responsibility. His impact on the telecommunications sector in Guatemala is undeniable and his influence continues to be felt, not only in the industry but also in the next generation of leaders. This is a story that transcends business. It’s a story about shaping a nation’s future.
