Mobile internet, 4G and 5G in Nigeria

Nigeria has four operators: MTN Nigeria, Airtel Nigeria, Globacom (Glo), and T2 — the rebranded former 9mobile. Per regulator NCC's own figures for July 2026, the country had 195,108,814 active mobile subscriptions, a teledensity of 90%. MTN holds 51.76% of the market (100,859,578 subscriptions), Airtel 34.26% (66,760,297), Globacom 12.13% (23,628,966) and T2 1.85% (3,613,801) — MTN and Airtel combined therefore hold more than 85% of all connections. Of active connections, 54.31% run on 4G and 4.74% on 5G, against 4.42% on 3G and 36.54% still on 2G — a share of active connections, not a national coverage percentage, and we never present it as one.

Broadband penetration climbed steadily: 53.86% in February 2026, up from 53.07% in January and 51.97% in December 2025, driven mainly by mobile broadband (3G and 4G). Nigeria's own National Broadband Plan (2020-2025) targeted 70% penetration, a target it ultimately missed. On 5G, MTN Nigeria is furthest along: it targeted a launch from the third quarter of 2022 across seven cities — Lagos, Abuja, Port Harcourt, Ibadan, Kano, Owerri and Maiduguri — after a testing phase in August 2022. Airtel Nigeria followed by 21 June 2023, initially in Abuja, Lagos and Port Harcourt, with plans to expand further. No confirmed commercial 5G launch was found for Globacom or T2, so do not write that all of Nigeria, or all four operators, have 5G.

Roaming in Nigeria without an eSIM

Nigeria is outside the EU and the EEA, so 'Roam Like at Home' does not apply. That arrangement covers the EU member states plus Iceland, Liechtenstein and Norway, along with Moldova and Ukraine — Nigeria is not among them. Your Belgian or Dutch bundle therefore stays behind: your operator bills every megabyte at its own out-of-bundle roaming tariff, without the EU price caps. Check that tariff with your provider before you go.

Just your passport: buying a SIM as a tourist in Nigeria

Nigeria provides a clear answer to a question that often went unanswered elsewhere: exactly what must a visitor show to buy a local SIM? Regulator NCC answers it itself, in plain words, on its own FAQ page 'Foreigners Living In Nigeria Or Visiting From Abroad': 'foreigners on tourist or visiting visa are to tender their international passports to acquire a SIM' — tourists and short-stay visitors need only present their international passport. A NIN (National Identification Number), the number Nigerian citizens and long-term residents deal with so often, is not required for a tourist.

If your status later changes to residency or a work permit, you will then need to obtain a NIN and link it to your SIM, per the same NCC page. Foreign residents staying more than two years in Nigeria need a NIN regardless; those staying less than two years are exempt from that requirement but must present the biodata and visa pages of their international passport. For a short-stay tourist, the rule stays simple: passport only, no NIN, no proof of a local address. Third-party travel guides also fairly consistently describe SIM counters in the arrivals halls of the Lagos and Abuja airports, consistent with this NCC rule — though that is not operator-confirmed, so we do not cite any specific counter as established fact. The Ariya eSIM goes one step further still: not even that passport needs to be shown, since it is already active before you even take off.
