Gone is MTN’s 2.5TB Yearly Plan, a mammoth data package for 365 days. In this post, learn why the code *312*136# fails, why the plan was removed, and how data-heavy users can assemble similarly large volumes—albeit at a higher price.

2.5 terabytes (2,560GB) is an enormous amount of data—previously enough to support a year’s worth of continuous high-definition streaming, online collaboration, or large-scale backups. MTN’s 2.5TB plan captured the attention of power users who preferred a single transaction for 12 months of worry-free data usage.

However, along with other year-long mega-bundles, 2.5TB vanished after MTN’s February 13 reshuffle. Let’s dissect why it disappeared, how people once bought it, and what alternatives remain for such colossal data requirements.

What Happened?

• Plan Discontinuation: The 2.5TB Yearly bundle is no longer listed or available via USSD or the MyMTN NG App.
• Consolidation: The entire range of multi-terabyte annual plans—1TB, 2.5TB, and 4.5TB—was phased out in one go.
• Market Realignment: With monthly or 2-month data deals now at the forefront, enormous year-long packages don’t fit MTN’s new structure.

Purchasing the Plan Before Removal

• Dial *312*136#: If you had the funds (often exceeding ₦500,000), you’d confirm purchase and instantly receive 2.5TB valid for 365 days.
• MyMTN NG App: The plan occasionally appeared under “Mega Bundles.” Payment could be from MoMo, bank card, or airtime.
• Exclusive Price Tier: Because of the huge cost, it was used predominantly by large businesses or extremely heavy individual consumers.

The Old MB Rate

Assuming 2.5TB was around ₦500,000, you got:

• 2.5TB = 2,560GB = 2,621,440MB
• Cost Per MB = ₦500,000 / 2,621,440MB ≈ ₦0.19

This remarkable rate placed it among MTN’s cheapest cost-per-MB offerings, overshadowed only by the now-removed 4.5TB plan and some older bulk deals.

Why Is It No Longer on MTN’s Website or USSD Menu?

• Complete Product Purge: Once the plan is retired, all official references vanish. Searching *312*136# yields an error, and old links can show “404.”
• Profit & Strategy: Ultra-cheap cost per MB might hamper revenue growth if only a few big spenders lock in that rate for a year.

Why the USSD Code Fails

The system no longer recognizes the product. If you attempt *312*136#, you’ll get:

1. No Plan Found: Indicating the SKU is gone.
2. Invalid Response: Generic error for a retired code.

Possible Replacements for 2.5TB

To replicate 2.5TB over a year, you must combine multiple smaller packages:

1. Monthly Big Plans
• For instance, 250GB monthly at ₦55,000 each—12 times. That would yield 3,000GB (3TB) across a year but cost ₦660,000.
2. 2-Month Plans
• 200GB for 2 months at ₦50,000, repeated six times, equals 1,200GB total at ₦300,000 for the year—far short of 2.5TB. Doubling that is 2,400GB at ₦600,000, still less than 2.5TB by 160GB.
3. Business Accounts
• Some corporate solutions might approach 2.5TB or more, though these are not typically found on standard consumer menus.

Common User Queries

“Can I still dial *312*136# for 2.5TB?”

• No. That route is defunct.

“Why remove such a massive plan?”

• Telecom strategy: pushing monthly or bimonthly recharges, ensuring dynamic revenue updates.

“Is 2.5TB overkill for personal use?”

• For many, yes. But for heavy streamers or business tasks, it was perfect.

“Any chance it might return?”

• Possibly via special promotions, but not in the standard package lineup.

The Cost Per MB Battle

2.5TB at ~₦0.19/MB was extremely attractive. Recreating that cost with smaller bundles is hard. You often end up paying ₦0.22–₦0.30 or more per MB. Over millions of MB, that difference is substantial.

The Big Picture: Phasing Out Yearly Mega Deals

• Consistency in Pricing: Annual plans lock in rates for a year, limiting flexibility. By removing them, MTN can adjust shorter-term plan prices more easily if market conditions change.
• Customer Behavior: Many prefer monthly or 2-month plans for budget reasons, even if cost-per-MB is higher.
• Streamlined Offerings: With numerous old yearly plans removed, the USSD or MyMTN App menu is less cluttered.

How to Piece Together 2.5TB

If you genuinely need ~2.5TB in 12 months, you could:

1. Buy 250GB monthly for 10 cycles = 2,500GB. That’s ~₦55,000 x 10 = ₦550,000, possibly more if you do it exactly monthly for a year. This is higher than the old plan’s cost, but it’s one feasible route.
2. Mix 2-Month and Monthly: Perhaps you buy 200GB (2-Month) plans when you expect moderate usage, then top up with monthly high-volume if usage spikes.
3. Monitor Usage: Instead of a flat 2.5TB for all 12 months, you might only need 1–1.5TB. Evaluate your real consumption to avoid overspending.

Example Cost Analysis

Either way, matching 2.5TB exactly is difficult without paying significantly more or splitting your usage across multiple cycles.

Conclusion

The retirement of the 2.5TB Yearly Plan means fewer choices for those who want a massive, single-purchase data approach. While it was perfect for certain heavy users, the new emphasis on monthly or bimonthly offers might push them to adopt more frequent recharges—unfortunately at a higher combined cost.

Key Takeaway: If you truly require multi-terabyte consumption, look into corporate solutions or plan to buy multiple large monthly/2-month bundles. Keep watch for new promotions, but for now, the era of 2.5TB annual consumer bundles is over.
