Telecommunications company T2, formerly 9mobile, posted its first subscriber growth of the year in July, adding 290,601 new users.

The increase was driven by its recent infrastructure-sharing agreement with MTN, the country’s largest mobile network operator.

This marked the operator’s first monthly gain in nearly a year, following a period of steady decline in its customer base.

In July, T2 was also the only one among the four major mobile operators to register growth, as MTN, Airtel, and Globacom all saw their subscriber numbers fall.

Meanwhile, active mobile subscriptions in Nigeria fell to 169.1 million in July, down from 171.5 million in June.

The decline was largely due to losses across three mobile network operators, with Airtel accounting for the most significant drop, shedding 2.4 million subscribers during the month.

The telco’s active subscriptions fell to 56.5 million in July from 58.9 million in June. MTN also lost 106,345 subscribers, bringing its total to 89.1 million, while Globacom’s subscriptions declined by 143,701 to 20.7 million.

MTN remained the market leader with a 52.70 per cent share, followed by Airtel at 33.42 per cent.

Globacom held 12.26 per cent,while 9mobile, despite its recent gains, stayed in a distant fourth place with a 1.61per cent market share.

On July 3, 2025, 9mobile and MTN officially announced a national roaming agreement, approved by the Nigerian Communications Commission, allowing 9mobile customers to access MTN’s network nationwide.

Before the deal, T2 experienced significant subscriber losses due to a deteriorating network caused by insufficient funds for infrastructure development.

Under the national roaming agreement, T2 users can now make calls, send SMS, and use data via MTN’s network in areas where 9mobile’s coverage is weak or unavailable, supporting the telco’s long-term sustainability.
