As digital life becomes ever more central to work, education, and entertainment, Nigerians are prioritising value-packed unlimited data plans. In this comprehensive overview for August 2025, we present the Top 10 cheapest unlimited data plans in Nigeria, curated for reliability, affordability, and user experience.
Table of Contents
1. Smile UnlimitedLite (₦18,500/mo for ~60 GB FUP)
Smile Nigeria’s unlimited broadband plan, UnlimitedLite, begins at ₦18,500 per month with a fair‑use cap of approximately 60 GB and download speeds up to 8 Mbps. This is ideal for light-to-moderate users seeking consistent home broadband.
2. Smile UnlimitedEssential (₦27,700/mo for ~150 GB)
At ₦27,700 monthly, Smile’s UnlimitedEssential delivers around 150 GB of usage and 8 Mbps speeds. A good pick if you share across multiple devices, but sensitive to network coverage.
3. Smile Freedom 3 Mbps Plan (₦38,500/mo, 200 GB FUP)
This tier offers a larger 200 GB cap at steady 3 Mbps speeds for ₦38,500/month, keeping connectivity steady 24/7.
4. Smile Freedom 6 Mbps Plan (₦46,500/mo, 300 GB FUP)
Stepping up in speed, this plan supports up to 6 Mbps and a 300 GB fair‑use limit for ₦46,500/month.
5. Smile Freedom BestEffort (₦61,500/mo, ~1 TB FUP)
At ₦61,500 monthly, this is Smile’s highest‑cap plan (~1 TB) with best‑effort data delivery up to 21 Mbps.
While Smile leads in broadband-specific unlimited options, many Nigerians rely on mobile operators offering “always‑on” plans branded as unlimited. Here are budget leaders in that space:
6. MTN Always‑On Bundles (~₦5,500‑₦9,000/month)
MTN now offers capped-but‑pseudo‑unlimited plans. Notably:
- 18.6 GB Always‑On (620 MB daily cap) for ₦5,500
- 45 GB Always‑On (1.5 GB daily cap) for ₦9,000
These packages give continuous access, though daily thresholds apply to ensure fair use.
7. MTN 60 GB Broadband Plan (₦14,500/month)
Targeted at router and MiFi users, MTN’s 60 GB broadband bundle includes bonus YouTube streaming and reliable speeds at ₦14,500 per month.
8. Airtel Heavy‑User 200 GB Bundle (~₦20,000/month)
As reported by users, Airtel’s large broadband/data package option offers around 200 GB for ₦20,000—delivering excellent per‑GB value if coverage is strong in your area.
9. Airtel Unlimited-Like Plans (Monthly Tethering/Share Bundles)
Though Airtel doesn’t explicitly label plans “unlimited”, it offers tethering and share bundles that mimic unlimited usage above 100 GB levels with competitive pricing. For many users with moderate to heavy data demands, Airtel often emerges as the best value at scale.
10. Glo High‑Volume Monthly Bundles (~₦5,000–₦15,000)
Glo offers very low‑cost large bundle plans that rival unlimited tiers. Monthly data bundles include:
- 24 GB + bonus 4 GB for ₦5,000
- 50 GB + bonus 4 GB for ₦10,000
- 93 GB for ₦15,000
These packages deliver high usage at ultra‑affordable rates but lack the unlimited branding or fair‑use thresholds of broadband options.

Highlights & Recommendations
- Best value overall: For high‑volume users, Airtel and Glo offer excellent per‑GB pricing if network coverage in your region is dependable.
- Most reliable “broadband” service: Smile provides consistent performance with fixed fair‑use thresholds—ideal for home use where uptime matters.
- Cheapest always‑available plans: MTN Always‑On bundles offer continuous data access at the lowest monthly cost, though daily limits apply.
Conclusion
If unlimited data means unrestricted access without constant buy‑ins, then broadband providers like Smile lead the way—even if they apply fair‑use limits. But if you’re flexible, mobile operators’ high‑cap monthly plans can mimic unlimited behaviour at much lower costs per gigabyte.
Before subscribing, consider:
- Your location and network strength: Airtel or Glo might offer the best price, but only if your area has stable service.
- Usage pattern: Night data, call bundles or shared plans can boost value.
- Fair‑use policies: UnlimitedLite and UnlimitedEssential have FUP thresholds; truly zero‑throttling isn’t guaranteed.
