Gone is MTN’s 1TB Yearly Plan, which offered 12 months of large-scale data. Wondering why you can’t access *312*135#? Here’s the scoop on why it disappeared, why the code fails, and how to cover your long-term data needs post-removal.

The 1TB Yearly Plan was a favorite among those who despised frequent renewals. For a hefty lump sum—often well above ₦200,000—customers secured 1 terabyte of data valid for an entire year (365 days). It was a premium product targeting content creators, offices, and anyone streaming or uploading vast amounts of data.

Post-February 13, this plan joined other high-volume, long-term data bundles on the chopping block. Now, references to 1TB yearly have disappeared across MTN’s platforms.

Why Was It Removed?

• Profit and Market Trends: Telecoms shift away from ultra-long subscriptions to ensure more consistent renewal revenue and adapt more flexibly to changing data usage.
• Backend Overhaul: Plans like 1TB, 2.5TB, and 4.5TB (all yearly) were collectively removed, hinting at a top-level strategic pivot.
• Limited Adoption: A year’s worth of data at a high price might appeal to a niche group, leading MTN to phase out lesser-used offers.

Activation Before February 13

• Dial *312*135#: That USSD code let you buy the 1TB plan if you had enough airtime or a linked payment method.
• MyMTN NG App: Some users saw it under “Annual Plans.” Payment could come from MoMo, card, or direct bank.
• Cost: Typically ranged from ₦200,000–₦220,000 or more, yielding a cost per MB around ₦0.20–₦0.22.

Cost Per MB

For illustration, assume you paid ₦210,000 for 1TB (1,048,576MB). The cost per MB was:

• ₦210,000 / 1,048,576MB ≈ ₦0.20

This was extremely competitive, especially compared to daily or weekly deals. The major barrier was the large upfront payment.

What’s Changed in MTN’s Long-Term Plans?

• Complete Yearly Plan Removal: Not just 1TB—2.5TB and 4.5TB also vanished.
• Focus on 30/60/90-Day Windows: We now see monthly or 2-month data bundles. Some rumored 3-month deals exist, but no official year-long plan.
• Frequent Renewals: Instead of one big buy, you must re-purchase monthly or bimonthly, which can be costlier and less convenient.

Why the Plan Isn’t on MTN Channels

Once discontinued, these mega-yearly bundles are:

• Scrubbed from MyMTN App: No “Annual Plans” remain in the standard consumer tab.
• 404 on Old Links: The landing pages that used to describe or let you buy the plan have been pulled.
• USSD Nonexistent: Dialing *312*135# results in error or no prompt.

Potential Alternatives for a Year’s Coverage

You can replicate 1TB across 12 months in smaller increments:

1. 250GB Monthly
• At ~₦55,000 monthly, 12 consecutive months cost ₦660,000 for a total of 3TB if you use them fully. This far exceeds 1TB, but you might be paying more than you need.
2. 200GB (2-Month) Plans
• If each 2-month plan is ₦50,000 for 200GB, in 12 months you’d buy six cycles for a total of 1,200GB, costing ₦300,000. This is 200GB more than 1TB but might be costlier or cheaper depending on official pricing.
3. Enterprise or Corporate Deals
• If you truly need a year’s worth of data, contacting MTN’s business solutions might yield a tailored plan.

Frequently Asked Questions

• “Can I still dial *312*135# for 1TB?”
• No. The code is removed; the plan is unavailable.
• “Will it ever come back?”
• There’s no official word. It’s possible a promotional annual plan could appear in the future, but the standard lineup has changed.
• “Is monthly or 2-month the only way now?”
• Yes, for large volumes. No official 6-month or 12-month consumer plan remains.
• “Why remove a convenient plan for big spenders?”
• Possibly to push them into monthly or bimonthly renewals, thus generating more consistent revenue.

Underlying Motives for This Removal

• Revenue Model: Splitting a 1TB purchase into multiple monthly or 2-month cycles can yield higher total revenue for the network.
• Dynamic Pricing: Telecom operators may want the flexibility to adjust data rates over time, which annual plans lock in.
• Shift in Consumer Patterns: Some users prefer mid-range, monthly solutions instead of an enormous lump sum.

Constructing a Yearly Replacement

If you truly need around 1TB:

1. Buy 200GB (2-Month) x6
• You’ll get 1,200GB across 12 months, but at ~₦50,000 each time, that’s ₦300,000 total. The cost per MB can be around ₦0.25, which is higher than the old 1TB plan’s ~₦0.20.
• You do get 200GB extra overall, so weigh the tradeoff.
2. Purchase 250GB Monthly x4 to x5
• That’s 1,000–1,250GB in 4–5 months, though you’ll have to re-purchase multiple times through the year. The sum can exceed ₦220,000 if you want to match the old plan’s 1TB.
3. Combination Approach
• You might buy monthly or 2-month bundles as your usage demands. If some months are lighter, you can get a smaller monthly plan to reduce cost.

Cost-Per-MB Overview

A rough table:

Notably, to cover 12 months with the monthly 250GB plan, you’d buy it 12 times if you’re using data consistently, skyrocketing the total cost to ~₦660,000 for 3TB total (way above just 1TB). It’s flexible but not cost-effective if you only want 1TB for the entire year.

Final Thoughts

The 1TB Yearly Plan’s removal leaves a vacuum for super-heavy data users wanting a single purchase. Now, you face either bundling multiple 2-month subscriptions or frequently renewing large monthly plans. While that can be more flexible (you can adapt if your usage changes), it also can be more expensive and less convenient.

Key Takeaway: If you truly want year-round coverage, weigh how frequently you’ll consume high data volumes. You might find a combination of 2-month or monthly deals that suits your usage pattern—albeit at a higher total price than the old 1TB plan. Alternatively, watch for any corporate or SME deals that might approximate an annual plan with better per-MB rates.
