The Nigerian Communications Commission (NCC) has threatened to fine the country’s three largest mobile operators by subscribers – MTN Nigeria, Globacom and Airtel Nigeria – if they fail to improve the quality of their services by the end of November, local newspaper This Day reports. Following an independent monitoring exercise carried out by the NCC across the country, the regulator determined that the trio failed to measure up to key performance indicators, including call setup success rate and call completion rate. The NCC has subsequently given the three GSM operators a 30-day deadline, effective 1 November 2011, to improve their service quality. If they fail to do so, the cellcos face a fine of NGN5 million (USD31,000) and an additional penalty of NGN500,000 per day if the provision of poor quality services persists. In addition, any of the three operators that fail to meet the targets from 30 November 2011 will be barred from the further sale of SIM cards or addition of any new subscribers to its network.
