Using USSD Codes

USSD codes offer the fastest and most direct way to check your data balance on MTN. USSD stands for Unstructured Supplementary Service Data, and these codes provide instant access to your account information.

Here are the main MTN USSD codes to check your data balance:


To instantly view your data balance, simply dial *323# on your phone and press call. This will bring up your current MTN data balance on the screen within seconds.

For example, you may see a response like:

“Dear customer, you have 1024.12 MB remaining in your data bundle validity till 11:59 PM on 31/01/2023”.

This provides your remaining data, your total data allowance or bundle, and the validity period. MTN will also send you an SMS confirming your data balance figures for future reference.


  • Extremely fast and convenient
  • No need for internet access
  • Works on all phones


  • Only shows current data balance
  • Does not provide full account or plan details


The *131# code gives you access to MTN’s self-service menu. When you dial this code, you will see various account options.

To check your data balance, select option “1” for Data Plans. This will display details like:

  • Data plan balance
  • Total bundled data
  • Validity period
  • Data rollover information
  • Out-of-bundle usage

This provides more comprehensive data usage information compared to *323#. You can also use *131# to check airtime balance, opt-in for various plans, and more.


  • Get detailed data usage breakdown
  • Access full account menu


  • Slower than *323#
  • Have to navigate menu options

In summary, *323# is the fastest way to check just your data balance figure. But *131# offers extra details through the self-service menu.


The MyMTN app provides the most convenient way to monitor your data usage on-the-go directly from your smartphone.

Frequently Asked Questions about Checking MTN Data Balance

1. Why is my data balance not showing up after recharge?

It can take up to a few minutes after recharging before your updated data balance reflects across channels. Allow some time for the change to propagate after purchasing a data bundle before trying to check your balance again.

2. I’m unable to check my balance via USSD codes. What should I do?

If USSD codes are not working, check if you have sufficient airtime balance on your MTN line. There may also be temporary network issues. Try again after a while or use the MyMTN app or website instead.

3. What happens to leftover data after my plan expires?

Depends on your plan. Some MTN data bundles allow you to roll over unused data to your next renewal. For others, leftover data gets forfeited after the validity period. Check your plan details to confirm data rollover policy.

4. Why am I being charged out-of-bundle rates when I still have data?

Once your main data bundle is used up, your usage gets deducted from your airtime wallet at out-of-bundle rates unless you purchase another data bundle. Manage your usage to avoid unintended charges.

5. How can I purchase a data bundle on MTN?

You can easily buy MTN data bundles via USSD, MyMTN app, website, or by visiting an MTN store. Bundles range from daily plans, weekly, monthly, and longer validity periods.

6. My app shows a different data balance than the USSD code. Which is correct?

There can be minor variations in live balance across different check channels. Give it some time to sync up or consider the MyMTN app balance as the most up-to-date and accurate.

7. I recharged but haven’t received the data I paid for. What should I do?

Contact MTN customer service to report the issue. Provide your recharge details so they can investigate and credit the missing data bundle to your account if there was an issue processing the recharge.

8. Are there any charges for checking my MTN data balance?

No, checking your data balance via any of the USSD codes, MyMTN app or website is free. You only need to ensure you have sufficient airtime balance on your MTN line for USSD requests.

9. Can I transfer data from my MTN line to another number?

Yes, the MyMTN app allows you to transfer data from your main bundle to other MTN lines through the Share Data option. This helps you optimize usage across numbers on your account.

10. How do I keep track of data usage on my iPhone?

On your iPhone, go to Settings > Cellular to view cellular data usage. Alternatively, use the MyMTN app which provides iOS data usage tracking and alerts. Set data limits and monitor usage across individual apps.

11. What happens if I use up all my data balance?

Once your data bundle is exhausted, further usage will trigger out-of-bundle rates which are usually expensive. To avoid this, purchase an additional bundle or use free WhatsApp/Twitter/other social media bundles.

12. Is there a way to protect my data balance from unauthorized use?

Yes, you can add a personal identification number (PIN) to your SIM through MyMTN app or USSD. This PIN will be required for making purchases, checking balance and other activities.

13. How can I decrease my MTN data usage?

Use WiFi instead of mobile data whenever available. Also turn on Data Saver in phone settings to reduce data consumption by apps. Disable auto media downloads, limit streaming quality, and close background data for unused apps.

14. Why does my data balance decrease even when not using mobile data?

Some apps may still consume background mobile data even when you’re on WiFi. Check individual app data usage and disable background mobile access for apps not needing this.

15. What is the maximum data balance I can have at once on MTN?

MTN currently allows up to 1 Terabyte (1024 GB) of data balance on a SIM. Various bundle options are available to accumulate data up to this cap based on your usage needs and budget.


In summary, keeping a close eye on your MTN data balance ensures you maximize the value you get from your plan. Follow the methods in this guide that suit your preference, set alerts, and utilize data management features for optimal control of your data usage.
