SAO PAULO (Standard&Poor's) July 20, 2012--Standard&Poor's Ratings Services said today that its ratings on Oi S.A. (BBB-/Stable/--) are not affected by the Brazilian telecom regulator's (Anatel) decision to suspend Oi's sales of new voice and data plans in five Brazilian states. According to the regulator, which also suspended the sales of two other large mobile operators-–TIM and Claro--in different states, this action was due to customer complaints of weak service quality and insufficient investments from these companies in the past 18 months. The companies are required to submit an investment plan to Anatel in 30 days, with detailed measures to improve quality in those specific states. We don't believe this suspension will have a significant impact
