The NCA has been been monitoring MTN’s quality of service and Key Performance Indicators (KPIs) such as call drop rate, call setup time, call congestion rate, and stand-alone-dedicated control channel congestion rate since the suspension began at the end of November.
The Director-General of the NCA noted there has been continual improvement in the KPIs compared to their performance prior to the ban.
“Considering the continual improvement and the aforementioned engagement with the Authority to improve customer experience, the Authority, with immediate effect, has lifted the directive of November 30, 2012 to MTN to cease selling and/or adding new SIM cards/subscribers to MTN network until further notice,” the NCA said on its website.
NCA added that Scancom Ltd, owners of MTN Ghana, has actively engaged with it since the ban was placed to define and implement procedures that would improve customer experience, including 24/7 network monitoring and support services.
It is also collaborating with partners in improving response time and has formed a special crisis management team.
