available for Brasil Telecom Turbo and Telefónica Speedy subscribers. Brasil Telecom purchase In 2008, Oi announced it would purchase Brasil Telecom, creating a major Brazilian telecommunications company, already nicknamed "Supertele" or "SuperOi". 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. Criticism Oi has been criticized and fined by Anatel due to not being able to meet quality goals in their mobile phone service; they have also been criticized for poor customer service.
