How to Check Your Data Balance and Expiry on Any Network in Nigeria (2026 Guide)

Knowing your remaining data and when it expires helps you avoid unexpected disconnections and manage your internet usage better. In Nigeria, the major networks: MTN, Airtel, Glo, and 9mobile, now use standardized codes and official apps that make checking your balance quick and easy. 

1. MTN Nigeria

USSD Code:

Dial *323# on your MTN line and press send.

Your remaining data balance (and often expiry) will appear on screen. 

Alternative SMS (if available):

Send 2 to 312 to receive your data balance via SMS. 

App Method:

Use the MyMTN NG App to view your data balance and expiry details directly on your dashboard. 

2. Airtel Nigeria

USSD Code:

Dial *323# on your Airtel SIM and press send.

This shows your remaining data balance on the screen. 

App Method:

Open the Airtel Thanks App, log in with your number, and your data balance and expiry will be displayed. 

3. Glo Nigeria

USSD Code:

Dial *323# on your Glo line and press send.

This gives you your current data balance. 

SMS Method:

Text INFO to 127 to receive an SMS with your balance details (this can be helpful if USSD does not respond). 

App Method:

Use the Glo Café App to view data balance and validity from within the app. 

4. 9mobile (formerly Etisalat)

USSD Code:

Dial *323# on your 9mobile SIM and send.

Your remaining data balance will appear on your screen. 

Alternative (older code):

Dialing *228# may still work on some lines to display data balance, especially if you haven’t updated your SIM or codes. 

App Method:

The 9mobile app (ig9ite) also shows your data balance once logged in with your number. 

Quick Notes

• The NCC (Nigerian Communications Commission) has harmonized many telecom USSD codes across networks, which is why *323# works on most SIMs to check data balance.  
• If the USSD code fails, try the official network app; it’s often the most reliable way to view your remaining data and expiry.  
• Checking data balance via official apps also shows bonus plans (like night data) and total validity period more clearly.
