In 2025, the cost of internet in Nigeria keeps rising, but MTN Smart Data gives users a way to fight back. MTN subscribers are now switching from regular bundles to MTN Smart Data plan because they offer bigger data volumes at cheaper prices.
These MTN Smart Data bundles are not visible through the popular *312# code. Instead, users must dial *121# to access them. That’s why many people online call them “hidden bundles.” From students to remote workers, more Nigerians are choosing Smart Data every day because of the clear value it brings.
In this guide, you’ll learn exactly how to activate MTN Smart Data using *121#, the latest plans available, what people are saying online, and expert insights into how to save money on data in 2025.
What Is MTN Smart Data and How Does It Work?
MTN Smart Data is a type of discounted data plan that MTN Nigeria offers under its TopDeal4ME menu. These Smart Data bundles are only available by dialing *121#, and they are personalized based on how you use your SIM card. MTN studies your recharge frequency, call patterns, and previous data use, then gives you special offers that match your behavior.
Unlike regular MTN bundles that stay the same for everyone, Smart Data changes depending on who is checking it. That’s why some users see ₦2000 for 10GB, while others might get ₦2500 for 12GB. MTN uses this to encourage loyalty and reward frequent users.
Data expert Chuka Odo from TechWise Africa explains it this way: “MTN Smart Data is like having a personal discount store inside your SIM. The more you use it, the more value you unlock.”
This strategy makes Smart Data more attractive than traditional data plans. Many users now visit the *121# menu daily to check for fresh offers before buying any bundle.
How to Activate MTN Smart Data on Any MTN Line
To activate any Smart Data plan on MTN, follow these simple steps on your mobile phone:
- Dial *121# using your MTN SIM.
- Select option 1: TopDeal4ME.
- Choose option 4: Smart Data.
- Pick the plan you want—1 Day, 7 Days, 14 Days, or 30 Days.
- Confirm your selection to activate the bundle.
Once you activate a Smart Data plan, MTN will send you a confirmation SMS. The message will include your data volume and the plan’s expiry date. If the Smart Data menu doesn’t appear, you can also check the Data4ME or VAS4ME sections in the same *121# menu.
Some users on Nairaland suggest switching your phone to 4G or inserting the SIM in another phone if Smart Data doesn’t show up. Others say they leave the SIM idle for 2–3 days, then recharge ₦100, and Smart Data reappears.

MTN Smart Data Daily Plans (1-Day Offers)
The MTN Smart Data daily bundles are great for light users who only need internet access for 24 hours. These plans offer value for short-term use like checking emails, chatting, or even downloading one or two apps.
Here are the current daily Smart Data plans available through *121#:
- ₦200 for 800MB – good for messaging, browsing, or updates.
- ₦250 for 1GB – perfect for light streaming or checking socials.
- ₦300 for 1.5GB – useful for YouTube, TikTok, or downloads.
- ₦1000 for 4.5GB – works well for movie streaming or Zoom meetings.
- ₦1500 for 7GB – ideal for users who need a lot of data in one day.
MTN users online often say this category is perfect when your main bundle finishes and you need urgent backup. Many Twitter users call the ₦250 for 1GB plan their “daily plug.” Some even set reminders to buy it every morning.
MTN Smart Data Weekly Plans (7-Day Offers)
If you need internet access for a full week, the MTN Smart Data 7-day bundles give you a mix of affordability and data volume. These plans are ideal for remote workers, online students, and social media users.
Below are the current 7-day Smart Data plans under the TopDeal4ME menu:
- ₦1000 for 5GB – great for daily apps and light streaming.
- ₦1500 for 7GB – perfect for those attending virtual classes.
- ₦2000 for 11GB – ideal for remote jobs, Zoom calls, and downloads.
One student on Facebook shared: “I use the ₦1500 plan for 7 days. It covers my lectures on Google Meet and still streams movies.”
Compared to MTN’s standard weekly plan of 1.5GB for ₦500, these Smart Data plans clearly offer better value. That’s why users are now skipping the *131# bundles completely.
MTN Smart Data 14-Day Plans (Updated 2025)
The Smart Data 14-day plans are for people who want something longer than one week, but not as long as a full month. These two-week plans give more flexibility to users who don’t want to recharge too often.
MTN currently offers the following 14-day Smart Data options via *121#:
- ₦2000 for 10GB – great for casual browsing and emails.
- ₦2500 for 12GB – perfect for moderate YouTube and TikTok use.
- ₦3500 for 17GB – best for those who need internet for work or business.
Freelancers in Facebook groups say the 17GB plan is their go-to choice. It gives them enough data to work, stream, and upload projects for two weeks straight. Several users mention using this instead of the normal monthly bundle because it feels “less risky” if something changes in their routine.
MTN also allows unused data from 14-day Smart plans to roll over if you renew the same plan before it expires. That means you get to keep any leftover MBs without wasting your money.
MTN Smart Data Monthly Plans (30-Day Offers)
The MTN Smart Data monthly bundles are perfect for users who need consistent and heavy internet access. These 30-day plans are available under the Smart Data menu via *121#, and they deliver some of the best data-per-naira value on the MTN network.
Here are the current 30-day Smart Data plans for 2025:
- ₦3500 for 16GB – ideal for students and online shoppers.
- ₦4000 for 17GB – great for social media, YouTube, and moderate streaming.
- ₦5000 for 27GB – best suited for remote workers, gamers, or content creators.
Compared to the standard MTN monthly bundle that gives 20GB for ₦5000, the Smart Data 30-day plan adds 7GB extra for the same price. That’s over 30% more data without spending more money.
On Nairaland, users say this plan is the “best data bundle MTN has ever released.” One user shared screenshots showing how the ₦5000 plan lasts them an entire month of work-from-home Zoom meetings and Netflix downloads.
How to Check MTN Smart Data Balance
After activating any MTN Smart Data bundle, it’s important to monitor your balance so you don’t run out unexpectedly. MTN provides different ways to check your remaining data balance.
Here are three fast methods:
- Dial *323*4# to get your balance instantly.
- Send an SMS with “2” to 312 – MTN will reply with your data usage.
- Use the MyMTN App – download it on Android or iOS and view your balance from the homepage.
Using the app is helpful because it shows both your main and bonus data balances. Many Smart Data users prefer it because it also reminds them when the bundle is about to expire.
MTN Smart Data vs Regular MTN Data Plans
When comparing Smart Data bundles to regular MTN data plans, the difference in value is very clear. Below is a direct comparison of what you get for the same amount:
| Plan Type | Amount | Data Volume |
|---|---|---|
| Smart Data (via *121#) | ₦5000 | 27GB |
| Regular Plan (via *131#) | ₦5000 | 20GB |
This 7GB difference means you get more freedom to stream, upload, browse, and download. Over time, that adds up to major savings.
Many users online say they’ve completely stopped using *131# since discovering Smart Data. On Twitter, a tech user wrote: “Only MTN Smart Data understands my struggle. 27GB for ₦5K? No brainer.”
What to Do If You Can’t See Smart Data Offers
Not all MTN users can see Smart Data bundles under *121#. These plans are personalized, so if your line doesn’t qualify, the offers won’t appear. But don’t worry—there are ways to improve your chances.
Try the following:
- Recharge your SIM regularly – Top up at least ₦100 weekly.
- Switch to 4G – Insert your SIM into a 4G device to get better deals.
- Check “Data4ME” or “VAS4ME” – These other options sometimes contain Smart Data plans.
- Leave the SIM idle for 2–3 days – Then recharge and check again.
- Rotate between multiple MTN SIMs – Different lines get different offers.
According to many online forums, users who were previously not seeing the offer suddenly had it show up after trying one of the steps above. MTN’s system updates regularly, so it’s worth checking back weekly.
Who Should Use MTN Smart Data Plans?
Smart Data on MTN works for almost everyone, but some people benefit more than others. These bundles help users who want more control over their data budget while getting better value.
Smart Data is best for:
- Students – especially those attending classes online or downloading lecture videos.
- Remote workers – who need stable, affordable data for Zoom, email, and Slack.
- Social media users – who stream, post, and browse all day.
- Casual users – who just want light bundles for WhatsApp or YouTube.
Even small business owners are using Smart Data to manage social media pages and attend online webinars. If you’re still using the normal *131# data plans, you’re likely paying more than you should.
