What Is the USSD Codes To Check Glo Data Balance? (*323#, *127*0#, SMS) Guide for 2026

To check your Glo data balance, dial *323# and read the reply. It shows how much data you have left and when it expires. If that code does not respond on your line, *127*0# is the older alternative, and a text message works too. That is the whole answer, and the rest of this page makes sure you never get stuck.

Many people check their balance only when a page refuses to load. A better habit is to check it before you start something big, right after you buy a bundle and a few days before expiry. Each check is free, takes seconds and prevents the three most common data headaches: running out unexpectedly, losing data to expiry and paying twice for a bundle that was already credited.

Codes and menus change from time to time. If one of the methods below fails on your line, move to the next. At least one will always work.

The data balance methods at a glance

How to check with *323#

USSD does not need an internet connection, so this works even when your data is completely finished. It is the first thing to try when your browser stops loading.

How to check with *127*0#

This older code opens the data balance for your current plan. It has worked on most prepaid lines for years, although the newer code above is now the standard. If *323# fails, dial *127*0# before you assume anything is wrong with your line.

Checking by SMS

Some lines respond to a similar text sent to 127. The reply arrives as a message, so you can keep it as a record. SMS checks need a little airtime on some lines, so if the text will not send, use the code instead.

Checking in the Glo Café app

The app shows your data balance on the home screen, along with airtime and bonus balances. It is the clearest view when your bundle has a night portion or a bonus portion, because the totals are laid out separately instead of squeezed into a short USSD message.

Reading the reply

Any-time, night and bonus data

Your total can hide three different pools. Any-time data works at every hour. Night data works from 12am to 5am only. Bonus data comes from promotions and usually expires sooner. When a total looks big but your daytime browsing stops, one of the other pools is probably the reason.

Check before you start something big

A video call, a long stream or a large download can swallow gigabytes. Check your balance first. If you are short, buy a bundle before you start rather than discovering the problem halfway through.

Check right after you buy

Dial the balance code a minute after you confirm a purchase. If the new data has not appeared, wait a few more minutes before you try again. Buying twice on top of a delayed credit is the most common way people waste money.

Check a few days before expiry

Unused data is lost when the bundle expires, unless you renew the same bundle first. Set a reminder three days before the date in your reply. If a lot remains, use it. If not much remains, renew early to keep what is left.

A simple checking routine

1. Check after every purchase to confirm the credit and note the expiry.
2. Check once a week to compare your pace with the days left.
3. Check before large downloads, calls or streams.
4. Check three days before expiry and decide whether to renew early.

Find out where your data went

If the balance is lower than you expect, open your phone’s data usage screen. It lists each app and how much it used. Look for video apps, cloud backup and app updates. Turn off auto-play, set backup and updates to Wi-Fi only and restrict background data for the worst offenders.

Why the balance may differ from what you expect

When the check does not work

1. Check that your signal is good enough to run USSD.
2. Restart the phone and try again.
3. Confirm the Glo SIM is selected on a dual-SIM phone.
4. Try the other code or the SMS method.
5. Open the Glo Café app.
6. Try again later if the network is busy.

Error messages you may see

Dual-SIM phones

On a phone with two SIMs, USSD codes run on the SIM you choose. If you dial *323# and get a reply for the wrong line, or an error, check which SIM the phone selected. Setting Glo as the data SIM also makes sure your bundle is the one being used.

Is checking free

Checking your balance by USSD code does not cost you anything and does not use your data. SMS checks may need a little airtime on some lines. When in doubt, use the code.

Understanding MB and GB in the reply

Your balance may appear in megabytes or gigabytes. One gigabyte is roughly one thousand megabytes, though phones often count it as 1,024. A reply of 1,500MB is therefore about 1.5GB. Do not worry about small differences between what the reply says and what your phone shows. Rounding and the way each side counts account for them.

Set up a data warning on your phone

This gives you an early signal even when you forget to dial the code. It does not replace the real balance, because your phone cannot see night data or bonus data separately, but it catches fast drains early.

Work out a daily allowance

Divide the remaining data by the days left to expiry. If you have 12GB and 20 days left, your daily allowance is 0.6GB, about 600MB. If you have used more than that by lunchtime, you will know to slow down. This one sum turns a vague balance figure into a practical daily limit.

Checking a bundle you gave or received

Data shared or gifted to your line appears in your balance like any other bundle. If you expected a gift and cannot see it, check the balance and the app, then ask the sender to confirm the number they used. A single wrong digit sends the data to someone else.

Business and router lines

Lines used for business, MiFi devices and routers hold their own balances. Check them with the same codes, using the SIM from the device in a phone, or with the Glo Café app logged into that number. Keep a note of which SIM sits in which device so you check the right one.

Common myths about balance checks

Keep your account safe

A balance check needs nothing from you except your own phone. Never give your SIM details, PINs or recharge card numbers to anyone who contacts you offering to check or increase your balance. Only use the official codes, the official app or an authorised Glo outlet.

Using the balance to choose your next bundle

Your pattern across a few months is the best guide to the next purchase. If you routinely finish a bundle with a week left, step up one size. If you routinely end with a third or more unused, step down or renew early so the leftover carries over. Note the balance a week before each expiry and write it down. After three months you will see your real rhythm.

Travelling and the balance code

Within Nigeria, the balance codes work the same in every state. When you travel abroad, roaming rules and charges apply and the codes may behave differently. Check your roaming settings and your balance before you leave, and switch off data roaming if you do not plan to use it, so a background app cannot spend your balance in a foreign network.

One last tip: when you buy a new bundle, check the balance straight away and compare it with what the confirmation message promised. If the two disagree, you have caught a problem on day one, when it is easiest to report and fix.

A quick checklist

• Save *323# and *310# as contacts called Glo Data and Glo Airtime.
• Install the Glo Café app for the full breakdown.
• Check after every purchase.
• Set a reminder three days before every expiry.
• Review your pattern once a quarter.

Related codes worth saving

Saving data once you know your balance

• Use Wi-Fi for updates and backups.
• Turn on data saver in your browser.
• Download videos instead of streaming them repeatedly.
• Set a usage warning on your phone at about 80 percent of your bundle.
• Switch off apps you do not need in the background.
