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.
Summary of Working Methods
MTN: Dial *323# or send “2” to 312, or use the MyMTN App.
