The Brazilian telecom regulator Agencia Nacional de Telecomunicacoes (Anatel) has reportedly directed the country’s second largest cellco by subscribers, Telecom Italia-backed TIM Participacoes (TIM Brasil), to suspend a recently launched tariff. According to the Wall Street Journal, the watchdog has claimed that TIM Brasil’s ‘Infinity Day’ plan, which offers unlimited local calls to other TIM subscribers for BRL0.50 (USD0.24) per day and unlimited long-distance calls for a further BRL0.50, could impact on the quality of service provided. For its part, TIM noted that in an investment plan presented to Anatel in August 2012 it had included the then yet to launch Infinity Day tariff, but no issues were flagged with it at the time. Further, the operator has refuted the suggestions that the launch of the calling plan would affect its network, saying that it had tested the impact of the new offer in the southern state of Rio Grande do Sul without any issues. Anatel, however, has now given TIM Brasil 30 days to present a proposal demonstrating that its network is capable of handling the volume of calls likely to be generated by the new tariff. In the meantime, if the operator fails to stop selling the plan it faces a fine of BRL200,000 per day, the regulator confirmed.
