Glo vs MTN vs Airtel Nigeria: which network to choose when sending credit from abroad

Roughly 17 million Nigerians live outside Nigeria, and the UK-Nigeria, US-Nigeria, and Canada-Nigeria corridors together move billions of dollars in remittance every year. A non-trivial slice of that lands as mobile credit — calling Mama on Sunday, putting airtime on Uncle's phone, keeping a younger sibling's line topped up while they finish school. This guide is for you if you've ever stood at Heathrow and asked yourself "is Mama on Glo or MTN?"

The four networks at a glance

MTN Nigeria

The dominant player. Originally South African (parent: MTN Group), with the largest subscriber base by a wide margin and the deepest 4G coverage outside Lagos and Abuja. Brand is the yellow MTN logo; you'll see it on retail stores in every market town in the country.

Strengths: nationwide coverage including Borno-state north and the Niger delta, biggest retail and agent network for in-person top-ups (which still matters in Nigeria more than in most diaspora corridors).

Weaknesses: typically the most expensive operator per minute and per MB. Customer service is famously slow.

Glo (Globacom)

The indigenous heavyweight. Founded in 2003 by Dr. Mike Adenuga — the only one of the four with truly Nigerian ownership. Sells itself as the "data king" on price and runs aggressive promos for the diaspora corridor specifically (Glo has long targeted UK / US Nigerians).

Strengths: cheapest data bundles in Nigeria, strong urban coverage, marketing leans hard into the diaspora- sending-credit-home theme so the recharge process is friction- less.

Weaknesses: rural coverage outside the southwest is thinner than MTN. Voice-call quality has historically lagged.

Airtel Nigeria

Subsidiary of Bharti Airtel (India). Roughly third by subscriber base but climbing fast on the back of cheap data plans and a strong push on mobile money (Airtel Smartcash). Particularly popular in the north (Kano, Kaduna, Sokoto).

Strengths: data pricing competitive with Glo, improving 4G build-out, the SmartCash mobile-money rails are useful if your relative needs a way to convert airtime to cash for groceries.

Weaknesses: still smaller agent/retail network than MTN.

9mobile (formerly Etisalat Nigeria)

The fourth and smallest. Rebranded from Etisalat after the Mubadala-led owners exited in 2017. Still focused on the post-paid / business segment, smaller subscriber base. Most of your relatives are NOT on 9mobile — but if they are, they know it.

How to tell which network your relative is on

Like Morocco, Bangladesh, and the Philippines, Nigeria implemented mobile-number portability (MNP) in 2013 and the prefix-to-network mapping has been getting blurrier ever since. The four operators share an 080, 081, 070, 090, 091 first-three-digit space and have historically been allocated specific four-digit blocks within those, but MNP means the prefix is now a 70% signal at best.

The reliable methods, easiest first:

Ask.Most Nigerians know which network they're on — it's a daily-cost decision tied to the data bundle they buy.
Read the SIM packaging or the carrier label at the top of their phone screen.
Use the NCC portability checkerat the Nigerian Communications Commission's website for ported numbers.

Historical prefix blocks (70% accurate for un-ported numbers):

MTN: 0703, 0706, 0803, 0806, 0810, 0813, 0814, 0816, 0903, 0906, 0913, 0916
Glo: 0705, 0805, 0807, 0811, 0815, 0905, 0915
Airtel: 0701, 0708, 0802, 0808, 0812, 0901, 0902, 0904, 0907, 0912
9mobile: 0809, 0817, 0818, 0908, 0909

Pricing from the diaspora corridors

Three things determine what you pay to recharge a Nigerian number from abroad:

The face-value denomination (NGN 500, 1000, 2000, 5000, 18000, 23500, 27000 — Nigerian operators sell in weirdly-specific denominations to align with bundle pricing).
The mid-market FX rate of your currency to NGN that day. Nigerian naira has been volatile post-2023 devaluation, so rates move 1–3% a week.
The margin the recharge site takes — which is hidden inside the "your price" quote and typically 10–25% over mid-market.

For an honest live comparison on the most-used denominations and corridors, see our per-corridor pages:

Other corridors (Germany, UAE, South Africa, Dublin) and other denominations exist; the URL pattern is /c/en/topup/NG/<operator>/<denom>NGN/<country> if you want to construct one directly, or email usif your corridor isn't there.

So which one should your family pick?

If they already have a SIM: don't make them switch. The cost of updating their number on every WhatsApp group and bank- registration form is way higher than the savings on the recharge side.

If they're picking a new SIM:

Lagos / Abuja / Port Harcourt, heavy data user: Glo. Cheapest data, urban-optimised network.
Rural Nigeria, mostly calls: MTN. Largest agent network for in-person top-ups, deepest rural coverage.
Northern Nigeria: Airtel. Their network is strongest in Kano / Kaduna / Sokoto and the agent banking ecosystem is good if your relative uses SmartCash.

The diaspora-specific stuff

Three things every UK-Nigerian or US-Nigerian should know:

Glo runs the most generous diaspora-specific bonuses.Send 5000 NGN from abroad and your relative often gets 6000 NGN credit + a data bonus. The catch: the bonus balance has a 7-day expiry and rolls into a separate sub-balance you can't use on bundles. Worth it for heavy-talk relatives, not for data-only.
MTN's Pulse and YafaYello plans require activation on the SIM, not on the recharge.If you load 2000 NGN to an MTN line that's not on a bundle, the credit gets burned at the regular per-minute rate (typically NGN 11/minute) within a few calls. Make sure your relative has activated a Pulse / YafaYello / Beta Talk bundle BEFORE you recharge.
Avoid SWIFT-based recharge services. Some older sites still settle via bank rails which take 1–6 hours and add a fixed £3–£8 SWIFT fee even on top of the FX margin. Stick to API-based recharge (Parlo, Ding, Reloadly) for near-instant delivery.
