MTN Nigeria has announced plans to carry out a scheduled network maintenance exercise on Saturday, October 25, 2025, that will temporarily disrupt connectivity across parts of Adamawa, Borno, and Kano States.

According to MTN, the two-hour maintenance window, from 6:00 a.m. to 8:00 a.m., will affect 101 network sites across 15 Local Government Areas in the three states.

The telecom giant explained that the planned work is part of a long-term effort to improve service reliability and strengthen its fibre infrastructure in northern Nigeria.

The activity involves a fibre cutover on a newly relocated cable segment between AFCOT and Bawo Village, replacing previously damaged spans and reducing multiple joints that have affected optical performance and network stability.

MTN disclosed that the affected areas include Nasarawa LGA in Kano State; Girei, Song, Mubi North, Hong, Gombi, Fufore, Mubi South, Madagali, Michika, Maiha, Chibok, and Yola North in Adamawa State; as well as Askira/Uba and Shani in Borno State.

The company noted that services on 2G, 3G, 4G, and 10 enterprise connections will be unavailable during the maintenance window due to the linear and unprotected nature of the fibre route.

It said the intervention builds on an earlier network restoration exercise conducted in August 2025 along the same AFCOT–Bawo fibre route.

This next phase, it added, is a more comprehensive upgrade designed to eliminate long-term faults and ensure more stable connectivity for customers in the region.

While acknowledging that customers may experience temporary service disruptions, the company expressed regret over any inconvenience caused.

“MTN regrets any inconvenience this may cause and appreciates customers’ understanding,” the statement read.

It would be recalled that earlier in August, MTN announced a similar scheduled maintenance in the same states to fix damaged fibre cable.
