A half-year of abundant data—MTN’s 800GB 6-Month Plan offered just that. Now, the code *312*115# draws a blank. Learn what caused the removal, why no alternative exists at the moment, and how to piece together big data over six months.

The 800GB 6-Month Plan was among MTN’s extended packages, tailor-made for individuals or businesses wanting stable, long-duration coverage. By paying a lump sum, you could avoid frequent renewals and enjoy a large data allowance spread over half a year. This convenience ended abruptly after February 13, leaving heavy-data loyalists searching for a new strategy.

The Disappearance

• No Trace: Once the plan was pulled, it was also removed from the MyMTN NG App, official web pages, and USSD references.
• New Emphasis on Shorter Terms: With 6-month and 12-month plans now gone, MTN seems to be steering large-volume users to monthly or 2-month solutions.
• No Official Statement: Like other big plans, the retirement came quietly, with no direct explanation from MTN.

Purchase Methods Before February 13

• Direct USSD: Dialing *312*115# would prompt you to purchase 800GB for 6 months.
• Online or MyMTN NG App: If you had the money in your airtime, MoMo wallet, or via card, you could purchase through those channels as well.
• High Upfront Cost: The price often ranged from ₦150,000 to ₦180,000, giving a cost per MB of around ₦0.18–₦0.23.

Cost Per MB

If we assume a middle estimate of ₦160,000 for 800GB (819,200MB), that breaks down to roughly:

• ₦160,000 / 819,200MB = ~₦0.20 per MB

This rate matched or undercut many monthly or shorter-term data deals, making it attractive for those who didn’t mind the upfront expense.

Why It’s Gone

• Profitability & Strategy: Ultra-long subscriptions may not align with MTN’s push for more frequent renewals.
• Simplification: Maintaining numerous extended plans can make USSD menus bloated and confuse customers.
• Market Demand: Possibly a small user base overshadowed by monthly or 2-month plan adopters.

Why *312*115# Fails

• SKU Removal: The plan’s unique product ID was stripped from MTN’s database. Dialing the code now triggers an “invalid” message or no response.
• No Replacement: Unlike some daily or weekly plans that were replaced by near equivalents, there is no direct 6-month plan as of now.

Possible Alternatives for 6 Months

If you still crave a six-month coverage:

1. Multiple 2-Month Plans
• For instance, you could buy 200GB (2-Month) thrice to span six months. That’s 600GB total at ~₦50,000 each purchase, totalling ₦150,000.
• The cost/MB is slightly higher than the old 800GB plan, and you get less overall data.
2. Monthly Bulk Plans
• Repeatedly purchasing 250GB monthly at ₦55,000 can accumulate a large volume, though you’ll be paying more frequently.
3. Enterprise Solutions
• SMEs or corporate clients might find specialized deals if they contact MTN business services, although these are typically customized and not the same as the old consumer plan.

User FAQs

• “Can I still buy 800GB for 6 months?”
• No. It’s discontinued; no official plan matches that volume or duration.
• “Why do old links show an error 404?”
• MTN removed or archived the relevant web pages. The plan no longer exists in official catalogs.
• “Is there a rumored 6-month plan replacement?”
• None is confirmed at the moment. Occasional rumors surface online, but results are mostly errors if you try to purchase.
• “What about bridging 6 months with smaller combos?”
• You’ll have to do multiple recharges—monthly or 2-month at a time. It’s less convenient but the only route now.

The Broader Context: Phasing Out of Extended Plans

• Yearly Plans Also Removed: 1TB, 2.5TB, and 4.5TB yearly bundles are gone. This indicates a comprehensive retreat from extremely long data packages.
• MTN’s Potential Rationale: Encouraging monthly or bimonthly top-ups means more consistent revenue flow and fewer discounted per-MB rates.

Reconstructing a 6-Month Solution

To approximate the old 800GB plan:

1. 2-Month Plans
• Three consecutive 200GB (2-Month) plans yield 600GB total for 6 months, at ~₦150,000 total. That’s still less data than 800GB, and cost per MB is ~₦0.25.
• Alternatively, 150GB (2-Month) thrice is 450GB total at ~₦40,000 each cycle = ₦120,000. Even less data.
2. Combining Monthly High Volume
• 250GB monthly at ₦55,000 repeated six times over half a year is 1,500GB for ₦330,000, which is huge volume but extremely expensive.
• You might do smaller monthly combos to approach 800GB.

In both cases, the cost typically exceeds what the old 800GB 6-month plan offered, and the usage is segmented into multiple subscriptions.

Below is a snapshot:

As you can see, none of these precisely replicate the old cost or data volume, leaving previous 800GB users in a bind.

Conclusion

The removal of the 800GB 6-Month Plan underscores a larger pattern: MTN has moved away from offering massive data volumes for extended durations. This shift likely stems from a mix of profitability concerns, usage analytics, and strategic decisions to standardize around monthly or bimonthly billing cycles.

Key Takeaway: If you used 800GB in six months for business, streaming, or personal use, you’ll need to piece together your data from the new monthly or 2-month offerings. While that might be more expensive per MB, it’s currently your only official route. Keep an eye on potential promotions or enterprise deals if your usage justifies a specialized plan.
