Buying data in Nigeria in 2026 feels like a part-time job. Prices have gone up, networks keep quietly adjusting their bundles, and what looked like a good deal last month might not be the same today.

The good news is that if you know which network to use, and which plan to pick for your specific usage habits, you can still get solid value for your naira. This guide breaks down the best and cheapest data plans in Nigeria across all four major networks: MTN, Airtel, Glo, and T2 Mobile (formerly 9mobile), so you can stop guessing and start saving.

Why Data Prices Changed in 2026

Before comparing plans, it helps to understand the pricing landscape. In January 2025, the Nigerian Communications Commission (NCC) approved a 50% increase in telecom tariffs, the first tariff adjustment in over a decade. All four mobile networks subsequently raised their data and call prices within weeks.

The networks argued that years of naira devaluation and rising infrastructure costs had made the old pricing unsustainable. Whether you agree with that or not, the new prices are what they are. The goal now is to get the most out of what you spend.

There is also one major structural change worth noting: in late 2025, 9mobile rebranded to T2 after being acquired by Lighthouse Telecoms. They also signed a national roaming agreement with MTN, allowing T2 customers to use MTN's network in dead zones. That is a significant improvement for former 9mobile users who struggled with coverage.

The Quick Verdict (If You Are in a Hurry)

  • Best value per gigabyte: Glo
  • Best network coverage: MTN
  • Best for unlimited data: Airtel
  • Best weekly deal: T2 Mobile
  • Best for social media only: T2 Mobile or Airtel social packs

Now let us look at each network in detail.

MTN Data Plans 2026

MTN remains Nigeria's largest network by subscribers and coverage. Despite not always having the cheapest prices, MTN has the widest network coverage in Nigeria (over 60% market share) and generally the most reliable service. If you travel frequently across states or live in areas with spotty coverage from other networks, MTN's reliability often justifies its pricing.

Selected MTN plans worth knowing:

  • ₦75 for 75MB (daily) - good for emergency browsing only
  • ₦350 for 1GB (daily) - one of the best same-day plans available
  • ₦800 for 1GB (weekly) - decent for light weekly users
  • Monthly plans available from ₦1,000 upwards via *131# or the myMTN app

Best for: People who travel often, live outside major cities, or need consistent 4G connectivity.

USSD to check balance: Dial 1314# or use the myMTN App.

Airtel Data Plans 2026

Airtel is the go-to network for anyone who wants unlimited data on mobile. Their network quality in urban areas is competitive with MTN, and their bundle variety is among the widest.

Selected Airtel plans worth knowing:

  • ₦500 for 1GB + 1GB bonus (weekly) - strong value at this price point
  • ₦750 for 2GB + 2GB bonus (weekly) - one of the best weekly offerings
  • ₦1,500 for 5GB + 2GB YouTube bonus (weekly)
  • ₦10,000/month for unlimited mobile data - the most accessible unlimited plan in Nigeria
  • ₦100 for 200MB social media data (2 days) - useful if you only need WhatsApp and Instagram

Airtel also offers binge plans for heavy weekend downloads, which are worth checking if you have large files to pull down.

Best for: Urban users, streamers, remote workers, and anyone who needs an unlimited option.

USSD to check balance: Dial *140# or use the MyAirtel App.

Glo Data Plans 2026

Glo consistently wins on volume per naira. If your priority is getting the most gigabytes for your money and you have decent Glo coverage in your area, this is the network to use.

For monthly plans, Glo's night data bonuses mean you are effectively getting far more data than what is advertised on the label. The catch is that you need to understand how the data is split before you subscribe.

Selected Glo plans worth knowing:

  • ₦50 for 50MB (daily) - entry-level daily plan
  • ₦500 for 1.5GB (7 days)
  • ₦1,000 for 2.6GB (30 days) - though note this includes night-only data
  • ₦3,000 for 10.5GB (30 days) - 8.5GB anytime data plus a 2GB bonus
  • ₦5,000 for 16.5GB (30 days) - strong monthly value for heavy users

Glo also offers a My-G social bundle: ₦100 for 300MB (1-day validity) covering WhatsApp, TikTok, Instagram, and Snapchat.

Important note on Glo night data: Glo heavily splits their allocations between "Anytime" data and night bonuses. Night data is only usable between 12 AM and 5 AM. Before buying a Glo monthly plan, confirm exactly how much of the bundle is anytime data versus night-only.

Best for: Budget-conscious users, night owls, students, and anyone who uses data heavily at home after midnight.

USSD to check balance: Dial 1270# or use the Glo Café App.

T2 Mobile Data Plans 2026 (Formerly 9mobile)

T2 Mobile is the rebrand most Nigerians have not fully caught up with yet, and that is partly why it is being overlooked. The national roaming agreement with MTN has addressed the biggest complaint about the old 9mobile network: poor coverage.

T2's 7GB weekly plan for ₦1,500 is a compelling deal, especially since you can fall back on MTN's network if the T2 signal drops.

Selected T2 Mobile plans worth knowing:

  • ₦400 for 1.5GB (1 day)
  • ₦1,000 for 1.5GB (7 days)
  • ₦1,500 for 7GB (weekly) - standout value in the weekly category
  • Social Paks from ₦25 for Facebook access (7 days) - for very light users
  • Combo voice and data packs via Moreflex Plus subscriptions

Best for: Value seekers who live in areas with reasonable T2 or MTN coverage, and anyone who makes a lot of voice calls alongside data use.

USSD to check balance: Dial *228# or log in to the T2 Mobile website.

Side-by-Side: Weekly Plans Compared

For most Nigerians, the weekly plan is the most practical option. Here is how the networks stack up at similar price points:

NetworkPriceDataValidity
MTN₦8001GB7 days
Airtel₦7502GB + 2GB bonus7 days
Glo₦5001.5GB7 days
T2 Mobile₦1,5007GB7 days

At the weekly level, T2 Mobile offers the most raw data, while Airtel offers strong bonus value. Glo wins on entry price. MTN lags in volume but leads in coverage reliability.

Common Mistakes Nigerians Make When Buying Data

Buying by price alone without checking the split. A Glo plan that says 3.7GB for ₦1,000 sounds great until you realise a portion is night-only data you may never use.

Ignoring coverage in your area. The best plan is useless if coverage is poor where you live or work. Always test a small plan first before committing to a monthly bundle on a new network.

Letting data expire without checking. MTN allows unused data to roll over if you renew within the grace period. Airtel supports rollover on select plans when renewed before expiry. Knowing this can save you significant data.

Buying from unverified third-party vendors. Stick to official network apps, USSD codes, or reputable VTU platforms to avoid being sold invalid or overpriced data.

Pro Tips for Getting More From Your Data in Nigeria

  • Use night data deliberately. If your network offers night bonuses (Glo, Airtel SmartTRYBE), schedule downloads, software updates, and video streaming for after midnight.
  • Use social packs when you only need messaging. Spending ₦500 on regular data just to use WhatsApp all day is wasteful. Social packs exist precisely for this.
  • Match your plan to your usage pattern. Light users do well with daily or weekend plans. Students and remote workers generally get better value from weekly or monthly bundles.
  • Compare cost per GB, not just headline price. Divide the plan price by total usable gigabytes. That number tells you the real value of any plan.
  • Keep a backup SIM. Most heavy data users in Nigeria run two SIMs: one primary network for reliability, one secondary for when the main line is slow or expensive for a particular use case.

Conclusion

There is no single best data plan in Nigeria for everyone. It comes down to where you live, how much data you use, and what you use it for.

For pure mobile data volume, Globacom offers the most gigabytes per naira, especially with its night data bonuses and competitive monthly bundles. MTN edges ahead on network quality and plan variety. Airtel is the go-to for unlimited mobile data plans. T2 Mobile suits users who want strong weekly value and do not mind mixing voice with data.

The smartest move is to identify your primary use case, check the cost per GB on the plans available in your area, and test before you commit to a large monthly subscription. Your naira works harder when you are deliberate about where it goes.

Data prices in Nigeria change frequently. Always verify current plans directly via each network's official app or USSD code before subscribing.
