How to Check Your Data Balance on MTN, Airtel, Glo, and 9mobile in 2025

In 2025, many subscribers use MTN, Airtel, Glo, or 9mobile to stream, chat, or run daily tasks online. But sometimes, your data finishes too fast. It may feel like your MB just suddenly disappeared! That’s why checking your data-balance often is super helpful. I remember once.

I was working on a school project and watching a HD video. My data finished in no time, and I didn’t even know. I had to interpret some cryptic codes just to know how much data I had left. It’s better to stay ready with the right guide and methods.

Each network has its own way. With MTN, use USSD code *312#. You can also use their app or check the menu on your phone. It’s fast and helps avoid out-of-bundle charges. Airtel gives responses by SMS or through their official dashboard.

For Glo, there’s a new app, and you can rack your usage by time — like night or daytime. 9mobile has a simple USSD method, too. Most apps also show balances, even for leftover data.

MTN: Checking Data Balance

Dial 312# to check your MTN data balance using the USSD code, which shows your primary balance and is the most frequently used method, with possible updates in 2025.

USSD Codes

Dial 312# to check your data balance quickly.
You can also try 3124# or 1314# for bonus or remaining data.
If you don’t see the BAL text, follow the prompts on your screen to get your balance.

MyMTN NG App

Download the MyMTN NG App from Google Play Store or iOS App Store.
Login to the app and view your data balance on the dashboard.
Tap the Refresh button to display your latest balance after minutes.

Potential Issues

USSD like 312# may have congestion at busy times, causing delays.
If you have multiple data plans, wait for the list to load separately or check SMS for details.

Airtel: Checking Data Balance

Dial 140# to check your Airtel data balance. This method is functional and works for many lines. The codes are reorganized to be easy to use.

Current Codes

Dial 140# to check your Airtel data balance.
SMS or text messages will display the summary of your balance.
You can also use 312# or 141 for other checking options.

Airtel Thanks App

Download the Airtel Thanks app from app stores.
Log in and check your data balance on the dashboard of the home screen.
You’ll also get notifications for bonus or night data offers.

Common Problems

Older SIMs may cause issues with the code. Try logging out of the app and syncing again.
Refreshing the balance or menu may help if it’s redirecting or showing a variation in your account.

Glo: Checking Data Balance

There are multiple codes, so follow the recommended approach for accurate results.

Dial 777# or 127# to check your Glo data balance.

USSD & SMS

Dial 777# or 1270# to check your data balance.
You will receive SMS with balance details and bonus info.
Follow the prompts to get more details on weekend or night data.

Glo Cafe App

Download the Glo Café app for self-care and easy balance checking.
After logging in, the app will show your data balance in the front center of the screen.
You can also see bonus or promo details, including night and social-media-only offers.

Pitfalls

Outdated codes like 1270# may fail to work or deactivate on older Glo plans.
Mixing multiple offers such as bonus and night data may cause confusion, as these plans work individually.

9mobile: Checking Data Balance

Dial *228# or *200# on your 9mobile line to check balance using simple codes once linked to Etisalat.

USSD

Dial *228# or *200# to open the self-service menu and check balance easily.
Send a text with BAL to 229 to get your data balance via SMS.
These classic codes work fast and show your data details clearly.

My9mobile App

Download the My9mobile app on Android or iOS to see your usage data in real-time.
The app shows your leftover data, plan expiry, and roll over info clearly on the dashboard.
You can register your number and manage auto-renew settings from the app easily.
Visit 9mobile stores or use the app to check or change your plan anytime.

Common Issues

Sometimes you see System Busy because of Temporary Outages; this is short-lived.
If you have a social bundle like WhatsApp, you get Separate Balances showing data left for it, like 200MB.
When USSD shows errors, wait a bit and try again to check your data balance.

Checking Night vs. Day Data

Sometimes, cryptic messages cause doubt about your data. Using the app gives more clarity. Remember, night data is for night use only, not day.

9mobile gives Night Plan data like 0.5GB or 1.5GB for Social Night use.
Night allowances and day bundles are separate and work differently.
To check your balance, use the app or send an SMS.
Networks like MTN, Glo, and 9mobile show your data left clearly.

(Using Mobile Apps for Enhanced Monitoring)

All four networks now emphasize their official apps, which do more than just show balances:

The MyMTN App shows your data balance and real-time usage clearly.
Airtel‘s app offers integrated features like bill payment, loyalty points, and data usage graphs.
You can use your MoMo wallet in these apps for quick payments and to grab exclusive data deals.
These apps help with easy tracking of your data on NG networks without calling or dialing codes.

Why the apps? They’re convenient, show usage graphs, and sometimes give freebies to app users. If you prefer not to remember codes, these apps are ideal.

Troubleshooting Balance Checks

Sometimes, you dial a known code and get no response. Or the data usage in the app doesn’t match your actual usage. Here’s how to handle it:

If USSD codes like *312# or 3124# fail, try another code or move to a place with better signal strength.
A quick restart of your device can fix small network glitches fast.
Sometimes the app shows old info because it is outdated; update it to the latest version from the app store.
If checking still fails, call or chat with customer care on the network’s support line.
These simple steps usually solve balance check issues on MTN and other networks.

Understanding SMS Notifications

After a successful check, you typically receive an SMS that might look like:

The message will say something like: “Your Main Data balance is 245 MB” or “You have 1.2 GB Night Bundle valid until 29/10/2025.” This means you can use your data until the date shown.
You might also see: “Main Data: 500 MB, Social Bundle: 100 MB, Expires: 30/10/2025.” This tells you what type of data you have and when it will end.
If you’re using Airtel, they often send a full report right after you buy a plan. This shows how much data you got and when it will expire.
You should check your SMS after every recharge. It helps you know if the data balance is right or if there’s a mistake.

If you see multiple lines, each is a separate data category (e.g., bonus, night, social, streaming). The expiry dates also may differ.

Common Mistakes to Avoid

Use official short codes only. Always re-confirm them. Check on the website or social media of your network.
Turn off Wi-Fi before checking. Use mobile data. It works better in the right environment.
Know your expiry date. Many lose data this way. Even with extra or social data, it can go to zero.
After a reset or change, check settings. New year or updates may affect balance checking.

Balancing Multiple Subscriptions

It’s common to have more than one data subscription active simultaneously—for example, a monthly plan plus a weekly or night plan:

Always check which plan is used first. Social data or night data is typically deducted before your main monthly plan.
Keep an eye on the expiry date. When it’s nearing the end, make sure the right one is being recognized and displayed in your app or through SMS.
Open tabs in your browser or social app use browsing differently. Use separate tracking for midnight or night use to give attention to how each data type works.

Using Self-Service Portals

Beyond USSD and apps, each provider has a web-based self-service portal:

Visit mymtn.com for MTN. Login with your phone and enter the OTP.
Use airtel.com.ng/selfcare for Airtel. Login to see your data balance.
Check Glo at hsi.glo.com or GloCafé.
For 9mobile, go to 9mobile.com.ng and login to view your balance

These portals often display your current data usage. They’re handy if you prefer a laptop view or want to manage your plan from a desktop environment.

Real-Life Example

Funmi has an MTN monthly data plan and a Sunday special plan. She wants to know how much data is left. She dials 312# to check balance and gets an SMS.

Her main data shows 1.2GB valid until 25/09. The Sunday Plan shows 500MB for next Sunday. Funmi also uses the MyMTN NG app to get a detailed breakdown and see her daily usage logs.

This helps Funmi track her data usage for streaming and other things. She knows how much she has consumed and can plan her budget for the week well.

Why Data Balance Doesn’t Match Actual Usage

Sometimes your phone’s internal data meter and the network show different numbers; you may have a 2GB plan but your phone says 800MB used while the network says 1.2GB left.

The network may have a delay or buffer before updates show your true balance. It may not reflect data consumed in the last few minutes.
Some networks compress traffic or offer zero-rate apps and streaming promotions that your phone’s meter might not count fully.
App-specific bundles like social or streaming bundles are separate from main data. The operator sees these in lumps, so data usage is not always shown together.

Conclusion

Knowing how to check your data balance is vital in 2025 to avoid unexpected disconnections and out-of-bundle charges from Nigerian operators like MTN, Airtel, Glo, and 9mobile, which provide multiple ways to do so.:

Use USSD codes like *312# for MTN and *140# for Airtel to check quickly.
Send SMS commands such as INFO 127 for Glo or BAL 229 for 9mobile to get balance details.
Use mobile apps or online portals for real-time dashboards and to track your historical data usage.
These tools give you a full self-service experience to manage your data easily.

Always check your data balance and expiry dates on the official app or with a code.Watch your usage to keep your plan from going off or hitting a zero-data scenario.Confirm your separate allowances like social and night data to avoid extra costs and stay guarded.
