The telecommunications market in Sao Tome and Principe is a duopoly shared between the historical incumbent CST (majority-owned by Visabeira) and the challenger Unitel STP. As of early 2026, the country has significantly expanded its 4G/LTE coverage, reaching over 85% of the population. With the government’s focus on the blue economy and digital transformation, investments in subsea cable capacity have enhanced data reliability, making mobile communication faster and more accessible across both islands.
