Islamabad: PTA has carried out billing verification of all cellular mobile operators (CMOs) by using computer software based solution meant for such checks through NEMO tool. Currently, Mobile operators are offering per-second, 20-second, 30-second and per minute packages. For this purpose, 30-second billing package was selected as majority of the subscribers have opted for this package. One hundred (100) rupees scratch cards were loaded in the SIMs of all CMOs. In order to verify billing system of CMOs, on-net and off-net calls of different durations were made ranging from 28 seconds to 175 seconds.
During billing verification exercise, it was observed that billing systems of majority of CMOs were accurate and amounts were being deducted correctly in accordance with their advertised tariffs. Two of the mobile companies were found overcharging in some instances. It was observed that in most of the cases operators were giving benefit to their subscribers by charging lesser tariffs in comparison to their advertised tariffs.
