One SMS—code 186—and you’re sorted for twelve months. MTN’s 800 GB Annual plan grants roughly 66 GB every month at just ₦0.16/MB, perfect for WFH, binge streaming or a busy family router. Pay once, browse all year, no renewal drama. True peace daily.

Until late 2024 MTN offered 1 TB, 2.5 TB and 4.5 TB annual bundles. Those tiers have been retired; the company now focuses on one streamlined option that balances affordability with belly‑room:

This single‑tier structure is confirmed on MTN’s official data‑bundle page MTN Nigeria and the MTN online shop MTN eShop, as well as SmartSMSSolutions’ 2025 plan tracker SmartSMSSolutions.

 

Why Stick With an Annual Bundle?

 

Cost Comparison vs Other MTN Long‑Term Plans

*Assumes you repurchase enough times to span one full year.

Take‑away: While not the absolute cheapest ₦/MB on paper, the 800 GB bundle strikes a sweet midpoint: far less upfront cash than stacking four quarterly packs (₦360 k) yet delivers more than double the data of buying 45 GB monthly all year.

Who Should Buy the 800 GB Plan?

 

Pros & Cons

 

Usage Benchmarks—What Does 800 GB Look Like?

Mix and match realistically: you won’t hit all those maxima at once, but the table shows headroom.

 

Tips to Stretch Your Terabyte‑ish Stash

1. Quarterly audits: Set a calendar reminder every 90 days; check balance via 1314#.
2. Router quotas: Many 4 G/5 G routers let you cap per‑device usage—stops a single gadget from guzzling GBs.
3. Optimise video quality: Drop Netflix to 720 p on smaller screens (saves 40 %).
4. Schedule OS/game updates overnight: Networks are quieter, and you can group downloads in one session.
5. Renew on day 364: Any unused data rolls over into Year 2, effectively lowering your ₦/MB even further.

 

FAQ Round‑Up

Q : Do I get roaming data?

Roaming isn’t bundled. You’ll pay roaming data rates or need a separate pack.

Q : Can I layer smaller bundles?

Yes. If 800 GB finishes early, just buy a daily/weekly/monthly plan. The earliest expiry consumes first.

Q : Is auto‑renew available?

Absolutely—toggle during purchase or later in MyMTN. You’ll receive SMS alerts 14 and 2 days before renewal debit.

Q : What if I lose the SIM?

Visit any MTN store with ID for a SIM swap; data balance migrates to the new SIM.

Final Word

MTN’s slimmed‑down 800 GB Yearly bundle keeps the dream of “set‑and‑forget” data alive, albeit at a slightly higher ₦‑per‑MB than the retired terabyte giants. At ₦0.16/MB and a single renewal per calendar year, it remains an attractive proposition for households, work‑from‑home squads and content pros who value convenience almost as much as raw savings.
