Lagos has strong 4G coverage across Lagos Island, Victoria Island, Lekki, Ikeja, and main areas of the city. Lagos Traffic congestion is heavy, and having active data is important for ride-hailing and navigation. Abuja, the federal capital, has excellent 4G coverage in Maitama, Wuse, Garki, and the Central Business District. Port Harcourt and Kano have solid 4G in city centers.
5G has been launched by MTN and Airtel in select areas of Lagos and Abuja. The rollout is in early stages and covers specific parts of the cities. Most users operate on 4G LTE, which provides solid speeds for video calls, maps, and social media in main cities.
Northeastern Nigeria, particularly Borno State and surrounding areas, has security concerns and degraded infrastructure. Signal is available in Maiduguri city but the broader northeast has coverage gaps. The Niger Delta region has 4G in Port Harcourt and main towns. Remote creeks and bush areas in the delta have no reliable coverage. Download offline maps before any travel to remote areas.
