Timor Telecom, S.A. (TT) is an East Timorese telecommunications company, based in the national capital Dili.

[4] The shareholders of TPT were Oi (76%), the Harii Foundation – Sociedade para o Desenvolvimento de Timor-Leste (linked to the Roman Catholic Diocese of Baucau) (18%), and Fundação Oriente (6%).

In 2001, the United Nations Transitional Administration in East Timor (UNTAET) launched an international tender for the construction of a replacement telecommunications system.

[1] In 2009, it engaged ZTE, a Chinese equipment supplier, to expand its mobile telecommunications system and establish Wideband CDMA.

TT's monopoly was to be ended in response to overwhelming public opinion in favour of liberalisation, and in line with developments in the European Union and other countries in the Pacific such as South Korea.

[1] On 2 October 2013, Portugal Telecom and Oi, S.A., a Brazilian telecommunications company, announced that they would combine operations to form a new Brazil-based business.

[1] In 2013, it introduced three new customer plans, completed the renovation of all of its existing stores, and opened a new call centre at Timor Plaza [de].
