5G in Nigeria: Which Cities Have It and Is It Worth It?
The hype of 5G has been several years in the offing. Strategic speeds, reduced latency, new age of connectivity. However, in the year 2026, the reality of the 5G icon illuminating on the phone faces the Nigerian users with a confusing reality: videos continue to buffer and calls continue to drop.
It is time to be truthful, with more than 57,000 5G-ready devices in Lagos and Abuja not capable of connecting to any 5G network, and millions more wondering how much their premium is paid reflects in the real world, we need to make an honest evaluation.
It is here that 5G is in Nigeria at this point in time-and whether you ought to care or not.
The 5G situation in Nigeria.
In 2021, Nigeria granted 5G licences on a nationwide basis after bidding 5G spectrum at 820.8 million dollars. The Airtel Nigeria, Mafab Communication and MTN Nigeria were all charged a fee of $273.6 million as ten year licences. In 2022, and 2023, respectively, Mtn and Airtel became commercial. The 5G services are not yet commercial in Globacom and 9mobile.
Four years on, there is still low adoption. Among the 148 million internet subscribers in Nigeria, there are only approximately 5.59 million less than four per cent who are on 5G. Most of them continue to use 4G (31.75%) or 2G (57.78%) yet.
The development trend is slow and gradual:
December 2023: 1.04% penetration
December 2024: 2.26% penetration
December 2025: 3.77% penetration
What Cities really possess 5G coverage?
The brief response: Lagos, Abuja, Port Harcourt, and Kano are the leading 5G cities, and Airtel is currently increasing to 20 big urban areas.
Operators have confirmed cities with 5G:
City MTN 5G Airtel 5G Mafab 5G
Lagos Yes Yes Planned
Abuja Yes Yes Announced
Port Harcourt Yes Yes Unknown.
Kano Limited Expanding announced.
Ibadan Limited Unknown Announced.
Benin City Limited Spreadsheet Announced Unknown.
Unknown principal enforcement date announced: Enugu\ Limited.
Kaduna Limited Announced Unknown.
Abeokuta No Yes Unknown
Warri No Announced Unknown
Owerri No Announced Unknown
Uyo No Announced Unknown
Calabar No Announced Unknown.
The aggressive Airtel 2026 expansion: In February 2026, Airtel confirmed it is accelerating its 5G rollout after increasing the number of active 5G sites by more than twice in the past three months. The company intends to tie the 20 leading cities in Nigeria to 5G networks and a large proportion of its network in these cities will turn 5G enabled next year.
The status of MTN: being the first player, MTN became operational in 190 locations within Lagos and Abuja first and has gone on to increase. The raw coverage footprint is also still lead by MTN, but the company has the same infrastructure challenges as competitors.
The truth test: There is spotty coverage even in these cities. According to NCC data, the coverage gap in Lagos is 70.9 percent, that is, large areas of the city do not have effective 5G coverage despite the commercial introduction. The coverage gap of Abuja is 65.6%.
This is the reason as to why the 41,057 5G-enabled devices in Lagos and 16,143 5G-enabled devices in Abuja fail to connect to any 5G network. The equipment is prepared; the networks are not.
How Fast Is 5G Really?
When it works, 5G delivers.
Speed tests in 2026 are independent and show:
MTN 5G: 400 Mbps-1 Gbps average speeds in urban areas, and 15 ms of latency.
Airtel 5G: Lagos and Abuja 300 Mbps to 700 Mbps average and 20 ms latency.
To provide a context, 20-50 Mbps is generally realized by 4G. The speed jump is real.
Controlled tests do not correspond to real life. There are reports of users in Lagos, Abuja, and Port Harcourt:
Screen sharing with dropped video calls.
Confirmations of transactions that hang up in times of peak.
Online tutorials that lose connection when showing full signal strength.
Buffering on even the 5G icon.
The disparity between the peak speeds and the actual performance is because of congestion, backhaul capacity, and infrastructure constraint in highly populated locations .
The Problem Behind the Curtain: You Bought 5G and Got 2G.
The frustration of the consumer is boiling. Subscribers anticipated a similar improvement in the service after a 50 percent increase in the telecom tariff passed in 2025. Rather, most of them state that their experience has deteriorated.
One of the operators of a Lagos business centre filmed the feeling: I could see the 5G icon turning on and full bars indicating good signal. But my video still buffers. Confirmation of payment stalls. The calls drop. This was not what we were guaranteed of.
Digital marketing consultants note that they have switched to voice calls in-meeting due to the 5G connections going dead in the middle of the presentation. Transaction delays are noticed by fintech merchants after undermining customer trust. Students complain about failure to stream 30 minutes lectures.
The Association of Licensed Telecommunications Operators of Nigeria (ALTON) has admitted that 3G and 4G cover more than 70% of Nigeria and 5G covers only around 11% of the country.
What is Causing the Disconnect?
Infrastructure deficit: 5G deployment will be an extremely expensive undertaking. The cost of deployment is 200,000 to 500,000 to install Macro 5G sites. Initial projections indicated that the total amount of the top cities was 6,000 sites at half a billion.
Fibre vandalism: ALTON Chairman Gbenga Adebayo warns that continuous fibre cuts interfere with network stability. Once it is cut it is a bridge being destroyed that brings whole areas together. Banking systems are influenced. Schools are affected. Hospitals are affected" .
Power outages: Poor and unstable power supply is still a significant limitation to performance stability.
Network outages: 281 major network outages occurred in Nigeria alone between May and June of the year 2025; that is, every 2.5 hours on average. By December 2025, operators registered 118 outage incidents within the country.
Enforcement of regulations: NCC has already brought pre-enforcement notices to operators, which will impose cumulative penalties of approximately N12.4 billion on them as a result of not fulfilling service benchmarks. With changed QoS rules, the operators will pay fines of up to N5 million per offense and other daily fines of N500,000.
Consumer groups however raise the question of whether punishment has been translated into visible change.
Which 5G Network is superior Airtel vs MTN?
Factor MTN 5G Airtel 5G

Coverage Footprint Wider (introduced previously) Expanding fast (targets 20 cities)
Pricing Premium Lower priced, younger oriented.
Stability Stable in strong points Stability acclaimed, strains in peak.
Extras Equipment leases plans Student bonus plans.
Select MTN when: You must have fastest speeds, broadest coverage in existence, and enterprise level reliability.
