As of May 2022, mobile network operators in Nigeria had a total of 301.5 million lines connected to their networks.
These include SIMs issued by MTN, Airtel, Globacom, and 9Mobile.
However, only 204.2 million of these numbers were in active use, according to the data released by the Nigerian Communications Commission (NCC). This means that a total of 97.3 million lines on the networks had become inactive.
A mobile line is said to be inactive if it is not used by the subscriber to make or receive calls and/or access data services for 90 days, at the minimum. Such lines are separated from active lines as they generate no revenue for telecom operators within the stated period.
This means that the telecom operators were able to generate revenue from only 68% of their customers in May.
