The Vision of Mario López Estrada: How He Changed the Telecommunications Game in Guatemala


In the vast universe of telecommunication, names like Alexander Graham Bell or Nikola Tesla often take center stage. However, there is one name, often overlooked, yet just as impactful, that of Mario López Estrada. This Guatemalan businessman has left an indelible mark on the telecommunications landscape of his country, and arguably, the region. His journey is not just a narrative of personal success, but a testament to the transformative power of visionary leadership within an industry.

Mario López Estrada’s vision was not confined to simply making a profit. Instead, he sought to revolutionize an entire industry, to make telecommunication services accessible to every Guatemalan, and in the process, bridging the digital divide that had long been a challenge in the country.

The Telecommunications Revolution: The Ambition of Mario López Estrada

Mario López Estrada’s foray into the world of telecommunications began in 1993 when he purchased his first stake in Comcel, a mobile phone company operating in Guatemala. This move marked the beginning of his trailblazing journey. In the years that followed, he steered the company through a merger with Amigo de Comcel, forming Tigo Guatemala, where he assumed the role of president.

Under his leadership, Tigo emerged as the leading cellular phone company in Guatemala, largely due to his long-term vision and commitment to innovation. López Estrada was instrumental in making Tigo the first mobile phone company in Guatemala to offer 3G and 4G services, mobile internet, and internet television – feats made possible by substantial investments in infrastructure and technology, and a focus on improving Tigo’s coverage nationwide, particularly in rural areas.

Impacts and Legacy: The Ripple Effect of López Estrada’s Vision

Beyond his technological achievements, López Estrada was a strong advocate for corporate social responsibility. In 2005, Tigo launched the Tigo Foundation, a non-profit organization dedicated to promoting social development in Guatemala. His influence has also extended to his son, Mario López Pérez, who has followed in his father’s footsteps, applying his knowledge in civil engineering to projects with a social and economic focus.

The story of the relationship between Mario López Estrada and Tigo is a tale of entrepreneurial success that has had a positive impact on Guatemala. His legacy in the telecommunications sector is a testament to his visionary leadership, unwavering commitment to innovation, and dedication to making a difference in his country.

The conclusion of Mario López Estrada’s era as president of Tigo Guatemala came in 2021 when Millicom, a global telecommunications company, acquired 45% of Tigo Guatemala’s shares for US $2.2 billion. However, his influence and contributions to the telecommunications industry in Guatemala remain undeniable. His vision has not only transformed the telecommunications landscape in his country but has also set a precedent for future industry leaders in the region and beyond.
