For anyone using a Glo mobile line — whether for calls, SMS, or mobile internet — keeping track of your airtime (credit) and data usage is essential. If you don’t check regularly, you can end up unexpectedly unable to make calls, send messages, or browse the internet, just when you need it most. Fortunately, Glo provides simple codes and tools you can use without needing internet access to instantly see your remaining balances.
USSD Codes: The Fastest Way to Check Airtime and Data
USSD (Unstructured Supplementary Service Data) codes are short codes you dial right from your phone’s dial pad. They work on all phones — smartphones and feature phones — and don’t require internet.
Check Glo Airtime Balance
To check your airtime balance (how much credit you have left):
Dial: *310# and press call.
This code shows your remaining Glo airtime balance directly.
You’ll see a prompt or SMS reply with your current airtime. This is the quickest way to confirm your credit before making calls or sending messages.
Check Glo Data Balance
There are several useful codes you can use to check your data balance:
Method 1 — Standard USSD Code
Dial: *323# then press call.
This displays your current data balance and validity period — that is, how much data you have left and when it expires.
This standardized code (*323#) is now used across all major Nigerian networks and works reliably for Glo too.
Method 2 — Traditional Glo Code
Dial: *127*0# and press call.
This older method also gives you a breakdown of your data usage via SMS or pop-up message.
If the newer code doesn’t work on your phone for some reason, this is a great alternative.
Method 3 — Glo Menu
Dial: *777# → choose Data Options → then choose Check Data Balance.
This brings up a menu that you can navigate to see your data balance and manage other services too.
SMS Method: Another Way to Check Data
If your phone has trouble with USSD or you prefer text messages:
Open your SMS app
Send: INFO
To: 127
Glo will reply with your current data balance and expiry date via SMS.
This method is also helpful if your USSD isn’t responding or if you’re in an area with a weak signal.
Glo Café Mobile App: Balance + More
If you regularly use your phone for data and airtime, the Glo Café App makes checking your balances even easier.
How to Use
- Get the Glo Café App from Google Play Store (Android) or Apple App Store (iOS).
- Open the app and log in with your Glo number.
- Once logged in, the home screen typically shows your airtime and active data balances.
Besides balance checks, the app also lets you buy data, see your usage history, manage subscriptions, and contact support.
Online Self-Care Portal
If you have internet access and prefer using a browser:
Visit Glo’s self-care portal (e.g., on the Glo official site).
Log in with your phone number.
You’ll be able to see detailed information about your airtime, data, active plans, and expiry dates.
This is especially useful if you want a more visual interface or need to manage your subscriptions on a larger screen.
Tips for Managing Glo Airtime and Data
Here are some helpful habits to stay in control of your balance:
Check Regularly
Make it a habit to check your airtime and data balance frequently — especially before long calls or when you’re about to travel. This helps you avoid sudden disconnections.
Understand Different Plans
Glo offers daily, weekly, and monthly data plans. Each plan’s data and expiry can be different, so check the message or app screen carefully to see how long your data will last.
Keep Track of Expiry
Data and airtime both expire after a certain period. Checking helps ensure you use your value before it runs out without notice.
Use the App
The Glo Café App not only shows balance but can track usage over time, which helps plan how much data to buy next.
Common Questions
Are these codes free?
Yes — checking your airtime or data balance using USSD or SMS is free.
Why doesn’t the USSD work sometimes?
If your network signal is weak or the code was entered incorrectly, the request might fail. Try again after a moment. If the problem persists, try the SMS method or the app.
Can I check from outside Nigeria?
Yes — but you’ll need roaming and the same USSD might behave differently depending on international roaming setup. The app or online portal is usually more reliable when outside Nigeria.
