Are you looking for a one-time data purchase that lasts 365 days? 9mobile’s annual plan delivers big savings and maximum convenience. Explore pricing, data volume, cost-per-MB, and activation tips in this all-in-one guide to 9mobile’s yearly subscription.
For serious data consumers or anyone who hates frequent renewals, an annual data plan can be a game-changer. While monthly or quarterly plans require recurring payments, a yearly subscription lets you pay once and enjoy coverage for 365 days straight. In 2025, 9mobile offers a flagship 1TB annual plan that stands out for its enormous data volume and favorable cost-per-MB. This blog post delves into the advantages, considerations, and best practices for anyone eyeing a year-long data commitment with 9mobile.
Why an Annual Plan?
- Fewer Hassles
You won’t worry about renewing data every month, quarter, or six months. A single payment covers your entire year. - Lower Cost-per-MB
Larger lumps of data typically reduce the per-MB cost significantly—often making it the most budget-friendly option for heavy users. - Peace of Mind
If you rely heavily on mobile data for work, school, or personal use, having a year’s worth of data ensures you never face a sudden cutoff (barring complete usage). - Business or Family Use
Ideal for offices with multiple employees, or a family with numerous connected devices—just one plan for 12 months.

Who Benefits Most from 1TB?
- Content Creators
YouTubers, filmmakers, and photographers who upload massive files regularly. - Remote Employees
Individuals who handle daily Zoom calls, large email attachments, and constant cloud syncing. - Families & Shared Households
One plan for everyone’s streaming, gaming, and social media, spread across a year. - Small Businesses
Co-working spaces or offices can provide data connectivity without monthly overhead.
Calculating the Monthly Equivalent
1TB is 1,000GB. Over 12 months, that’s about 83GB per month on average. This might be plenty for moderate usage, though power users could burn through it faster. If you anticipate using more than 83GB monthly, you might need to ration data carefully or combine with a Wi-Fi solution.
Activation Steps
- USSD: Dial *312# and look for “Annual” or “365-Day” plan.
- My9mobile App: Head to the “Data Plans” section and choose the 1TB yearly subscription.
- Payment: Ensure you have enough credit (₦100,000) or use a linked debit card.
- Confirmation: You should receive an SMS or app notification once active.
Managing 1TB Over a Year
- Set Monthly Targets
~83GB per month is your baseline. If you surpass it consistently, you risk running out before year-end. - Data-Sharing Protocols
If multiple people/devices are using the same plan, consider setting usage limits or at least tracking usage to avoid early depletion. - Use Wi-Fi Where Available
Even though you have a massive data pool, it’s wise to offload big tasks to reliable Wi-Fi networks whenever possible.
Advantages Beyond Cost
- Reliable Network
9mobile’s coverage in major cities is robust, and the speeds can rival many broadband options. - No Monthly Caps
Some broadband services impose monthly usage limits. With 1TB for the year, you have flexibility in how you distribute usage across months. - Potential Business Tax Write-Off
If you’re using it for a company, the lump sum might be simpler for accounting or tax purposes.
Potential Downsides
- Huge Upfront Payment
₦100,000 is significant. Not everyone can or wants to shell out that amount at once. - Risk of Unused Data
If your usage changes or if coverage issues arise, you could be stuck with leftover data you can’t use or roll over past 365 days. - No Additional Night Bonuses
Typically, these large annual plans don’t come with separate night data. You get one big chunk for all usage times.
Comparisons: Annual vs. Other Long-Term Plans
- Bi-Annual (600GB @ ₦70000) → ~₦0.12/MB. Over a year, you’d pay ₦140,000 for 1,200GB if you repeated it twice. That’s more total data but more money.
- Quarterly (425GB @ ₦50000) → Repeating it four times a year = ₦200,000 for 1,700GB total. That might be overkill or too expensive.
- Yearly (1TB @ ₦100000) → ~₦0.10/MB is the cheapest rate if 1TB suffices.
FAQs
- Is 1TB truly unlimited?
While it’s a very large amount, it’s not labeled “unlimited.” There is a hard limit of 1,000GB.
- Can I roll over unused GB if I renew before the year ends?
Some rollover terms apply if you buy a new plan before expiration, but you must check if 9mobile offers another 1TB renewal or similar plan.
- What if I exceed 1TB before the year is up?
You’ll need to purchase an additional plan.
- How do I check my balance?
Use *228# or the My9mobile App.
- Does 9mobile throttle speed after a certain usage?
Generally, no official throttling occurs for capped plans. However, network congestion or coverage can affect speed.
Strategies to Make the Most of Your Year
- Set Automatic Updates
You can let your devices auto-update without worrying about monthly data constraints. - Collaborate with Others
Split the cost among a group if you trust them and share via hotspot or a MiFi router. - Use Business Tools
If you run a small business, integrate cloud-based software, data backups, etc., ensuring consistent connectivity.
Final Thoughts
A yearly 9mobile data plan is a major commitment—but for the right user, it’s an incredible deal in convenience, cost-efficiency, and peace of mind. Paying ₦100,000 upfront for 1TB might seem steep, yet if you’re consistently a heavy user or need stable connectivity for a full year, the savings can be remarkable compared to multiple smaller plans.
Before pulling the trigger, consider your average monthly consumption and confirm 9mobile’s coverage reliability in your region. If everything aligns—budget, usage, and coverage—then the 1TB annual plan is a fantastic, worry-free data solution. You’ll spend less time renewing and more time enjoying a robust, year-long connection.
