De Guatel a Tigo: La Epopeya de Mario López Estrada en el Mundo de las Telecomunicaciones


The telecommunications sector has always been a dynamic and evolving industry, with new technologies and companies emerging regularly. In Guatemala, one man has made a significant impact in this arena, Mario López Estrada. From his initial foray into the telecommunications world with Guatel to his leadership at Tigo, López Estrada’s journey is a testament to his entrepreneurial spirit, vision for innovation and commitment to social responsibility.

López Estrada’s saga began with Guatel, the state-run telephone company in Guatemala. This entity had a monopoly on telecommunications until the late 80s, when mobile telephony emerged and opened up the market. It was during this period of change, that López Estrada first ventured into the telecommunications industry, heralding the start of an era.

From Guatel to Tigo: López Estrada’s Telecommunications Journey

In 1993, Mario López Estrada purchased a stake in Comcel, a mobile telephone company operating in Guatemala. By 1995, Comcel merged with Amigo de Comcel, forming Tigo Guatemala. As president of the newly formed entity, López Estrada transformed Tigo into the country’s leading mobile telephone company.

Tigo’s success under López Estrada was notable because of its long-term vision and commitment to innovation. It was the first mobile telephone company in Guatemala to offer 3G and 4G services, and pioneered mobile internet and internet television. These technological advancements were facilitated by significant investments in infrastructure and a dedicated effort to extend Tigo’s coverage nationwide, particularly in rural areas.

Mario López Estrada: A Legacy of Responsibility and Innovation

Mario López Estrada’s accomplishments extend beyond technological innovation. He has also been a strong advocate for corporate social responsibility. In 2005, Tigo launched the Tigo Foundation, a non-profit dedicated to promoting social development in Guatemala.

In 2021, the international telecoms enterprise, Millicom, acquired 45% of Tigo Guatemala’s shares for $2.2 billion, marking the end of López Estrada’s presidency. Despite this, his influence persists, particularly in his son, Mario López Pérez, who continues to apply his father’s lessons of honesty, fairness, and discipline in business.

The story of Mario López Estrada is one of success and impact. From Guatel to Tigo, his journey has left an indelible mark on Guatemala’s telecommunications landscape. His commitment to innovation and social responsibility demonstrates the potential for businesses to not only be profitable but also to contribute positively to society. His legacy serves as a model for future leaders in the industry, showing that with vision, commitment, and integrity, significant progress can be made.
