Frequently Asked Questions

Which network has the best 4G coverage in Nigeria?+

MTN Nigeria has the most extensive 4G LTE coverage, reaching approximately 82% of Nigeria's populated areas as of early 2026. Airtel is second at around 75% coverage. Glo has the widest physical footprint in terms of rural reach but lower 4G density in some cities. T2 Mobile (formerly 9mobile) has the smallest coverage footprint, strongest in Lagos and Abuja.

Is 5G available in Nigeria in 2026?+

Yes. MTN launched 5G commercial service in Nigeria in 2022, initially in Lagos (Ikeja, VI, Lekki) and Abuja. By 2026, MTN's 5G covers approximately 35–40 of Nigeria's major cities. Airtel Nigeria launched 5G in 2024 and is expanding. Glo and T2 Mobile have not launched commercial 5G as of May 2026. 5G capable phones are required to access these networks.

Which network is cheapest for calls in Nigeria?+

For on-net calls (same network), all operators offer similar rates. For cross-network calls, MTN and Airtel have comparable rates. Glo has historically been cheapest for voice calls under certain tariff plans. T2 Mobile offers competitive rates for international calls. Since the 2026 NCC tariff review, per-minute rates have converged across operators — data plans now differentiate operators more than voice rates.

What is T2 Mobile (formerly 9mobile)?+

T2 Mobile rebranded from 9mobile in 2025 following acquisition by Teleology Holdings with new strategic investors. The network uses the same 4G LTE infrastructure as 9mobile but has invested significantly in network upgrades. T2 Mobile has approximately 13 million subscribers and is strongest in Lagos, Abuja, and south-south Nigeria. It is typically priced competitively to attract subscribers away from MTN and Airtel.

How do I check my network's coverage before switching?+

MTN's coverage map is at mtnonline.com/coverage-map. Airtel's is at airtel.com.ng/coverage-map. Glo's is at gloworld.com/coverage. T2 Mobile's is at t2mobile.ng/coverage. All are interactive maps. NCC also publishes Quality of Service (QoS) reports quarterly at ncc.gov.ng which rank operators by data speed, call drop rate, and coverage in different zones.
