478:, the largest telecommunication company in Portugal, in order to strengthen the Brazilian firm and simplify its ownership structure. The acquisition of Portugal Telecom was troubled; an issue with Portugal Telecom's financial cash flow was discovered in 2014, leaving Oi without additional capital. Main shareholder of the merged companies, Rioforte, ended up not paying the agreed amount of $ 1.2 billion dollars that should have been paid to Portugal Telecom in order to pay bonds. As a result, Oi had to default after the merger and reduce the participation of the company's former shareholders. Telemar Participações was incorporated by Oi, simplifying the corporate structure and terminating the shareholders' agreement.

That takeover required changes in legislation, which at the time prohibited a fixed telephone company from purchasing another fixed telephone company in a different license area. That legislation has changed since, and Oi completed its purchase of Brasil Telecom on January 9, 2009. Rollout of the Oi brand in the Brasil Telecom area starts with prepaid mobile service on May 17, 2009.
