Viva Dominicana, also known as Trilogy Dominicana, is a mobile network operator based in the Dominican Republic. Originally established in 1883 as All America Cables & Radio Dominican Republic, a subsidiary of ITT, it was the first telecommunications company in the country to provide telegraph services to the Antilles. In 2000, Centennial Communications acquired a 70% stake in the company, leading to its rebranding as Centennial Dominicana. In 2006, Centennial Communications sold 100% of its Dominican operations to Trilogy International Partners for US$80M. The company was subsequently renamed to Viva in April 2008. By the end of 2015, the Telemicro group, owned by businessman Juan Ramon Gomez Diaz, took over the operations of Trilogy Dominicana.
