How to Check MTN Data Balance
MTN Nigeria provides several ways for customers to check their remaining data. One of the quickest options is through USSD.
MTN data balance code
Dial:
*323*4#
You can also dial *310# and follow the available options. MTN says customers can also check their data balance by sending 2 to 323, using the myMTN NG app, or through its Zigi service.
After checking your balance, pay attention not only to the amount of data remaining but also to the expiry date. Having 2GB left does not help much if the bundle expires shortly.
Using the myMTN app
If you prefer seeing more information than a USSD message provides, the myMTN NG app is useful. The app allows customers to monitor data usage, check balances, buy bundles and manage other aspects of their MTN account.
How to Check Airtel Data Balance
Airtel customers can check their remaining data by dialing:
*323#
According to Airtel Nigeria's current FAQ, the other code displays the customer's active data subscriptions. Airtel also says customers can use the My Airtel self-care app to check their balance.
The USSD option is particularly convenient when you do not have enough data to open an app.
Check Airtel data through the app
If you have the My Airtel app installed, you can log in and view your account information from the app. This can be more convenient if you want to see your active plans and manage your subscriptions in one place.
How to Check Glo Data Balance
Glo subscribers have several options for checking their remaining data.
Glo data balance code
You can dial:
*323*0#
Glo also lists *312# as another USSD option for checking data-plan information. Alternatively, customers can send INFO to 312 or use the Glo online self-service platform.
If you have several active bundles, checking your balance regularly can help you understand which bundle is being consumed and when each plan expires.
Glo Café
Glo customers can also use the Glo Café app to manage their account and check their data information. This can be more convenient for people who prefer an app instead of memorising USSD codes.
How to Check 9mobile Data Balance
9mobile is now operating under the T2mobile name. T2mobile identifies itself as the former 9mobile and continues to provide voice and data services in Nigeria.
For customers still referring to the network as 9mobile, it is worth noting that some older online guides contain outdated balance codes.
Because network services and USSD menus can change, customers should use the current T2mobile/9mobile self-service channels where possible.
You can also check the network's current website and customer-support channels if a previously used code does not return your balance.
Quick Data Balance Codes at a Glance
Network
Data Balance Method
MTN
*323*4# or *310#
Airtel
*323#
Glo
*323*0# or *312#
9mobile/T2mobile
Use current T2mobile self-service options
Important: USSD codes can be changed or updated by network operators. If a code stops working, check the operator's official website or app rather than relying on an old code from a blog post.
How to Check Data Balance Using Mobile Apps
USSD is not the only option. Most Nigerian network operators provide digital platforms where customers can manage their accounts.
The advantage of using an official app is that you can usually see more than just your remaining megabytes or gigabytes. Depending on the network, you may also see active subscriptions, expiry dates, available offers and your usage information.
For example, MTN's myMTN NG app provides data tracking and allows customers to check their data and airtime balances.
If your network's USSD service is temporarily unavailable, the official app can therefore be a useful alternative.
Why Does My Data Finish So Quickly?
Checking your balance is only half of the solution. If your data seems to disappear faster than expected, your phone may be consuming data in the background.
Some common causes include:
1. Video streaming
YouTube, TikTok, Instagram and other video-heavy platforms can consume significant amounts of data, particularly when videos play at high quality.
2. Automatic app updates
Your phone may download application updates without you noticing.
3. Social media
Scrolling through photos, videos and reels continuously can use much more data than ordinary text-based chatting.
4. Cloud backups
Automatic photo and video backups can consume a considerable amount of mobile data.
5. Hotspot usage
If you share your mobile connection with another phone, laptop or smart TV, your data can be consumed much faster than normal.
How to Make Your Mobile Data Last Longer
You don't necessarily need to buy a bigger bundle every time your data finishes quickly. A few changes to your phone's settings can make a noticeable difference.
Turn off automatic updates on mobile data: Set your phone to update apps only when connected to Wi-Fi.
Reduce video quality: Watching videos in lower quality can significantly reduce data consumption.
Restrict background data: Some apps continue using the internet even when you are not actively using them.
Use data-saving features: Many social media and browser apps have built-in data-saving options.
Monitor individual apps: Check your phone's data-usage settings to discover which apps are consuming the most data.
T2mobile also provides guidance on managing data usage, including information about activities that can cause data depletion.
