The document outlines minimum quality of service benchmarks for mobile operators in Nigeria as defined by the Nigerian Communications Commission. The benchmarks cover key areas like customer complaints, speed of problem resolution, billing integrity, customer care, customer interface, and recharge cards. Operators are expected to maintain low customer complaint rates, clear most problems same or next day, have accurate billing with low error rates, ensure high call completion rates and short wait times for customer care, provide sufficient customer interface points, and process recharge cards with very low error rates.
