Nigerian mobile data is some of the cheapest anywhere in the world when you price it in dollars. MTN, the network that carries just over half of the country's 195 million lines, asks ₦4,500 for 10 GB over thirty days and ₦7,500 for 20 GB, and with the naira trading near ₦1,330 to the dollar in October 2026 those are about 3.40 and 5.60 dollars. A traveller who would pay 35 dollars for 10 GB on a travel eSIM is looking at a tenfold gap, and the gap is real, not a promotional teaser.
The catch is everything that happens before the bundle lands. A foreign visitor cannot just pay at a kiosk and walk away. The line has to be registered against your passport and entry visa, the store will normally take fingerprints and a photograph, and activation is not always instant. None of that is hard, but it costs a morning, and the morning is what this page helps you plan.

Registering a Line as a Visitor: What Actually Happens
Nigerian SIM registration has been tightened repeatedly since 2020, when the government began requiring every line to be linked to a National Identification Number. The final linkage deadline passed on 14 September 2024 and unlinked numbers were blocked. Visitors do not have a NIN, and the Nigerian Communications Commission's guidance for that case is short: foreigners on a tourist or visiting visa present their international passport to acquire a SIM. Residents on work or residence permits are expected to enrol for a NIN instead.
Carry the passport and the visa page
Bring the physical passport, not a photocopy, along with the visa, or a printout of the e-visa approval if that is how you entered. Some staff also ask for the arrival stamp, so keep it easy to find.
Go to a service centre, not a roadside umbrella
The agents under branded umbrellas sell recharge cards and sometimes SIMs, but foreign registrations go far more smoothly at an MTN or Airtel service centre where staff process passports every week.
Expect biometrics
The agent scans your fingerprints and takes a photograph against the passport data. Allow fifteen to forty-five minutes at a quiet store, longer on a Monday morning or a Saturday.
Test the line before you leave
Ask the agent to load your first bundle and confirm data works on the spot. If activation is pending, ask how long it will take and get the reference, so a second visit is quick.
The four-line limit and the second-hand SIM trap
Each person can hold at most four SIMs per operator. More important for a visitor is the market in pre-registered cards sold on the street, which are registered to someone else. They work until the operator audits them, and then they stop, sometimes with your bundle still on them. A line in your own name is the only kind worth paying for.
The honest cost of this process is time, and when you do it matters. A Tuesday at ten in the morning at a mall store in Ikeja or Wuse is painless. Saturday afternoon, with half of Lagos sorting out its own phone problems, is not.
MTN's Bundle Ladder in Naira
MTN publishes its full data price list on its own site, which makes it the easiest Nigerian network to shop with confidence. The prices below are taken from that list in October 2026. Dollar figures use roughly ₦1,330 to the dollar and are rounded. Most monthly plans also include a bonus of YouTube night data that can only be used between midnight and five in the morning, which is worth knowing but not worth planning around.
| Bundle | Price (₦) | About (US$) | Valid for |
|---|---|---|---|
| 1 GB daily | 500 | 0.38 | 1 day |
| 3.5 GB weekly | 1,500 | 1.13 | 7 days |
| 11 GB weekly | 3,500 | 2.63 | 7 days |
| 18 GB two-week | 6,000 | 4.51 | 14 days |
| 10 GB monthly, plus 10 minutes | 4,500 | 3.38 | 30 days |
| 20 GB monthly | 7,500 | 5.64 | 30 days |
| 36 GB monthly | 11,000 | 8.27 | 30 days |
| 75 GB monthly | 18,000 | 13.53 | 30 days |
Two things stand out. First, the weekly bundles are almost as cheap per gigabyte as the monthly ones, so a ten-day visitor can buy one 11 GB week and top up rather than committing to a month. Second, these prices already include the increase MTN applied in February 2025, when the regulator approved a tariff rise of up to fifty percent across the industry. Older blog posts quoting ₦1,000 for 1.2 GB a month are describing a market that no longer exists.
Buy bundles by code, not by asking
Once the line is live, dial *312# and follow the menu to pick a bundle from your airtime balance. That way you choose the exact plan rather than accepting whatever the agent selects, and you can repeat it from your hotel room when the first bundle runs out.
Airtel, Glo and the T2 Question
Airtel is the realistic alternative to MTN and the network Nomad's and Holafly's eSIMs already run on. Its monthly bundles sit very close to MTN's after the 2025 increase, with 10 GB over thirty days quoted at around ₦4,000 in mid-2026 price lists. Airtel's own website loads its price table through a script that did not render when we checked, so confirm the figure in the store or through the *312# menu before you rely on it. Coverage in the big cities is excellent. In the north and on long rural roads MTN usually holds on longer.
Glo was for years the cheap-data network, and its data prices are still competitive, but it has been losing subscribers through 2026 and sits at around 23.6 million lines. Its towers are strongest in the southwest. A visitor who already has an MTN or Airtel line gains little from adding Glo, although some long-stay visitors keep one as a backup for evenings when the bigger networks are congested.
T2 is what 9mobile became on 8 August 2025. It has kept shedding subscribers since the rebrand, and with roughly 3.6 million lines it is far too small to recommend to a visitor, whatever an agent says about promotional bonuses. If someone hands you a T2 card, ask for MTN or Airtel instead.

Where to Buy, City by City
In Lagos, the easiest stores for a visitor are the operator centres in the big malls, because they have air conditioning, generators that keep the registration terminals running, and staff who process passports regularly. Ikeja City Mall on Obafemi Awolowo Way is ten minutes from the airport on a good day, and The Palms in Lekki serves the island side. Computer Village in Ikeja is the city's sprawling phone market and is good for chargers, cases and repairs, but buy the SIM itself from an official counter rather than a stall there.
In Abuja, the operator centres around Wuse 2 and in the large malls handle foreign registrations routinely, and the city's orderly layout makes them easier to reach than their Lagos equivalents. In Port Harcourt, Ibadan, Enugu and Calabar there are MTN and Airtel service centres in the commercial districts. Smaller towns have plenty of recharge agents but may not have staff equipped for passport registration, so do not leave the purchase until you are upcountry.
What the airport counters are good for
MTN and Airtel representatives work the arrivals side of the international terminal at Murtala Muhammed, and they can register a passport. Their hours follow flight banks rather than office hours, and when several long-haul flights land together in the evening the queue builds quickly. Treat them as a possibility rather than a plan, and have data on an eSIM in case the desk is unstaffed or the biometric terminal is down.
Recharge is the easy part. Every neighbourhood has vendors selling scratch cards and electronic airtime for MTN, Airtel and Glo, supermarkets sell vouchers at the till, and most hotels can point you to an agent within a short walk. You do not need a Nigerian bank account to keep a line topped up; cash at a kiosk works everywhere.
Local Line or Travel eSIM: Where the Line Falls
Because the local card is so much cheaper, the decision in Nigeria is really a decision about time. A rough guide that holds for most trips:
| Your trip | Best setup | Rough data cost |
|---|---|---|
| Layover or one night | Travel eSIM only, a 1-day or 1 GB plan | 7.50 to 10.50 dollars |
| Business trip, 2 to 6 days | Travel eSIM only, 5 or 10 GB | 25 to 35 dollars |
| Holiday, 7 to 14 days | Small eSIM for arrival, then an MTN weekly bundle | About 10 dollars in total |
| Family visit, 3 to 6 weeks | MTN line with a monthly bundle, eSIM as backup | About 6 to 15 dollars a month |
The table assumes you can afford the registration morning. If your first day in Lagos is a 9am meeting on Victoria Island and your evenings are client dinners, that morning does not exist, and a 35 dollar eSIM is cheap insurance. If your hosts are relatives who will happily drive you to the mall on day two, the local line wins easily and gives you a number your family can call.
One last practical point: keep both. A dual-SIM phone can hold the local line and the eSIM together, and in a country where one network can slow to a crawl in the evening while another is fine, having a second network a tap away is worth far more than the few dollars it costs.
Frequently Asked Questions
Will a street vendor sell me an MTN card without my passport?
Some will, and you should not buy it. A card sold without your documents is registered in someone else's name, which breaks the rules the regulator has spent years enforcing. These lines tend to work until the operator runs a compliance check and then get blocked, sometimes with an unused bundle still on them. Go to a service centre with your passport and visa, and the line will be yours for as long as you keep it active.
How long does activation take after registration in Lagos?
Often a few minutes, sometimes several hours. The registration is captured on the spot, but the line may not carry data until the operator's system has processed it. Ask the agent to test data before you leave, and if it is pending, note the reference and keep your eSIM switched on until the new line comes alive. Visiting in the morning gives the line the rest of the day to clear.
Can I get an MTN eSIM instead of a plastic card?
MTN lists eSIM among its SIM services in Nigeria, and so does Glo, but the identity rules do not change because the SIM is digital. You still go through registration with your passport, normally in a store, before the eSIM profile is issued. That makes it a convenience for people who do not want to swap trays, not a way to avoid the paperwork or to arrive already connected.
Is a weekly MTN bundle enough for a ten-day stay?
Usually, if you buy the right one. The 11 GB weekly plan at ₦3,500 covers maps, messaging, ride-hailing and a reasonable amount of social media for most people, and you can add a second week or a smaller top-up from the *312# menu when it runs out. Heavy users who stream or tether a laptop should go straight to the 18 GB two-week bundle at ₦6,000 or a monthly plan.
What happens to my Nigerian number after I fly home?
It stays registered to you, but an inactive line is eventually recycled if it goes a long time without a recharge or usage. If you visit Nigeria regularly for business or family, keep a little airtime on it and use it occasionally, so the same number is waiting next time. If you came once, let it lapse. Remember that a visitor line registered on a passport needs to be linked to a NIN if you later become a resident.
