Explore MTN’s 3-month data bundles for 2025, offering 400GB and 600GB options with low cost per MB and extended 90-day validity. Ideal for heavy users and businesses, subscribe effortlessly via SMS, USSD, or SmartSMSSolutions.

Note: MTN has removed its yearly, 6-month, and 3-month data plans from its offerings. This move could be in anticipation of the NCC-approved price hike expected soon. If you rely on these long-term plans, you may need to explore alternative options. 

For subscribers who prefer not to renew monthly, 3-month (90-day) data bundles offer even greater convenience. MTN Nigeria’s 3-month plans typically come in 400GB and 600GB volumes—large enough to handle heavy usage scenarios like streaming, remote work, or content creation.

This guide covers MTN’s 3-month data bundles for 2025, explaining cost per MB, how to subscribe via SMS/USSD, and how to buy them online at SmartSMSSolutions.

• Massive Volume: 400GB and 600GB can support streaming, gaming, and large file transfers for 3 months.

2. USSD
• Some references mention *312*131# or *312*134#, but always confirm.

Who Should Consider 3-Month Plans?

• Content Creators: If you upload high-resolution videos frequently.
• Office Teams: If multiple people share a Wi-Fi hotspot, 400GB or 600GB can last a quarter.
• Heavy Streamers: If you watch or stream content daily, dividing 400GB across 3 months gives ~133GB/month, which can be more than enough.

Advantages and Disadvantages

Pros

• Lowest Cost per MB among many consumer plans.
• Reduced Renewal Stress: Just once every 3 months.
• Business-Friendly: Ideal for short-term offices or remote setups.

Cons

• High Upfront Cost: ₦50,000 or ₦75,000 might be steep for casual users.
• Data Monitoring: You need to ensure you don’t burn through all your data too quickly, as you won’t want to buy another large plan prematurely.

Comparing to Monthly and 6-Month Plans

• Vs. Monthly: If you buy 200GB monthly for 3 consecutive months, that’s 600GB total for ₦90,000. By choosing the 600GB 3-month plan, you pay ₦75,000—saving ₦15,000 and achieving the same volume.
• Vs. 6-Month: MTN offers an 800GB 6-month plan at ~₦0.11/MB. If you can stretch your budget and usage that far, you might get an even better rate. However, 3-month plans are more manageable if you’re unsure about half-year commitments.

FAQs

Is There a Rollover for These Plans?

• Generally yes, if you renew before the 90-day expiry, but the large volume makes it less likely you’ll have leftover data unless your usage is lower than expected.

Does This Work on 5G?

• Yes, all standard MTN data bundles are 5G-compatible as long as you have a 5G device and coverage.

Can I Buy Multiple 3-Month Plans at Once?

• You can, but it might cause overlapping validity. Typically, you’d wait near expiry or use up your data before purchasing again.

Usage Tips

• Track Weekly: With 90 days, it’s easy to lose track. Check your balance at least weekly to adjust your usage.
• Use Wi-Fi Scheduling: If you’re streaming or updating devices, consider a schedule that fits your data plan so you don’t blow it all in the first month.
• Plan for Overlaps: If 3 months ends on your project’s final day, perfect. If it ends earlier, consider bridging with a shorter plan.

Real-Life Examples

• Startup Office: A new business with five employees can purchase 400GB for 3 months. That breaks down to about 133GB/month to share among the team, likely enough for essential tasks.
• Seasonal Filmmaker: Shooting a documentary over three months, you might need stable data for file transfers, video conferencing, and more. The 600GB plan ensures you won’t run out mid-project.

Buying on SmartSMSSolutions

If paying ₦50,000 or ₦75,000 at once is easier through an online payment rather than airtime, use SmartSMSSolutions. The process is straightforward and you can even purchase from outside Nigeria.

MTN’s 3-month data bundles at 400GB and 600GB are excellent for heavy or business-centric usage, offering a low cost per MB (~₦0.12) and convenient 90-day validity.
