What is the code to check data balance?

Dial *323# on any network: MTN, Airtel, Glo or 9mobile (T2).

Why does my data balance show more than one bundle?

Each bundle you buy, and any bonus data, is kept separately with its own expiry date. The balance message lists them one by one.

*323# isn’t working. What should I do?

Dial *312# and choose the balance option from the menu, or check your network’s app. If neither works, call your network on 300.

How to check data balance on MTN, Airtel, Glo and 9mobile

Updated 1 October 2026

Quick answer

Dial *323# to check your data balance on MTN, Airtel, Glo or 9mobile (now T2). Your remaining data and its expiry date show on screen. For your airtime balance, dial *310#.

Balance codes for every network

To	Dial
Check data balance	`*323#`
Check airtime balance	`*310#`
Buy a data plan	`*312#`

These are the NCC’s harmonised codes, so they are the same on every network and replace the older codes each network used to have.

How to check MTN data balance

Dial *323# from your MTN line. If you have several bundles, such as a monthly plan and a bonus, each one is listed with its own expiry date. You can also see your balance in the MyMTN app.

How to check Airtel data balance

Dial *323# from your Airtel line. Your data balance and expiry show on screen. The My Airtel app shows the same balance.

How to check Glo data balance

Dial *323# from your Glo line. Use *323# rather than Glo’s older balance codes, which may not work any more.

How to check 9mobile (T2) data balance

9mobile is now called T2. The code hasn’t changed: dial *323#.
