"Over the past decade, MTN Ghana has invested over US$2.5 billion in network and information technology infrastructure," he said.

Lumor revealed that the network's focus on improving its data service speaks to an increase in subscriber demand. "More people are shifting to the use of data than expected, compelling us to work hard to satisfy the increasing demand."

The NCA's data showed that MTN is dominating the 4G wireless access landscape with about 60% share of the market, while the second-placed operator in the space Surfline has 30% market share.
