Millicom (Tigo) strengthens regional connectivity in Central America through strategic agreement with Trans Americas Fiber System

Luxembourg, 10 April 2026 –Millicom International Cellular S.A. ("Millicom"), a leading telecommunications company in Latin America, today announced a long-term commercial agreement with Trans Americas Fiber System (TAFS), a next-generation digital infrastructure provider, to expand and strengthen its international network infrastructure and resilience across Central America.

As part of this partnership, Millicom will enhance its international capacity through TAFS' open-access, carrier-neutral platform, reinforcing its ability to meet the region's rapidly growing demand for reliable, high-capacity digital services. The initiative supports Millicom's continued investment in infrastructure to drive access, economic development, and digital inclusion across the region.

The TAM-1 system is a next-generation subsea fiber optic network spanning approximately 7,000 kilometers, designed to establish direct links between the United States, the Eastern Caribbean, Central America, and South America (Colombia), with each fiber pair supporting a minimum of 18Tbps of capacity. The system comprises two complementary segments: a northern system connecting Hollywood, Florida with Mexico, Guatemala, and Honduras, and a southern system anchored by main trunk from Vero Beach, Florida to St. Croix (U.S. Virgin Islands), with connections to Puerto Rico and branches extending to Panama, Costa Rica, and Colombia.

Through this infrastructure, Millicom will benefit from increased route diversity, enhanced redundancy, improved network resilience, and greater scalability—key elements to ensure consistent, low-latency service for operators, enterprises, governments, and end users across multiple markets.
