USSD Codes to check Glo Data Bundle, Prices And Validity (Complete 2026 List)
Every Glo user has been there. You are browsing, the page freezes, and you wonder how much data is left. A few quick dial codes can answer that in seconds, and the same menus show you what bundles cost and how long they last.
This guide puts the main Glo data codes in one place: how to check your balance, how to see bonus and night data, how to open the data menu, and how to read the price and validity of each plan family. Dial the codes as you read, so you can see what shows up on your own line.
One honest warning first. Glo changes menu items, bonus sizes and prices from time to time, so always trust what your phone shows on the day you buy. Figures below are rounded guides, not promises.
What Glo USSD Codes Actually Do
A USSD code is a short number that starts with a star and ends with a hash, like *312#. You type it in the dialler and press call. A small menu pops up on your screen and you reply with a number to pick an option.
No internet is needed. This is why USSD works even when your data has finished, which is exactly when you need to check balances or buy a new bundle. It also works on cheap phones without apps.
The Main Glo Data Codes at a Glance
| Code | What it is used for |
|---|---|
| *312# | Opens the Glo data menu where you buy bundles |
| *323# | Checks your data balance |
| *127*0# | Older style data balance check that still works for many users |
| *301# | Opens the wider Glo self-service menu |
| *310# | Airtime balance check on many lines (check your menu if it fails) |
If one code gives an error, try another from the table. Networks sometimes retire a shortcut and move the same function into a menu.
How to Check Your Glo Data Balance
| 1 | Open your phone dialler and type *323#. |
| 2 | Press the call button and wait a few seconds. |
| 3 | Read the message on screen. It shows your remaining data and the date it expires. |
| 4 | If nothing shows, try *127*0# instead. |
Some phones show the answer as a pop-up and some send it as an SMS. If you see neither, wait one minute and try again, because the network can be slow at busy hours.
How to Check Your Airtime Balance
Airtime and data are kept in two separate wallets. Your airtime balance pays for calls, SMS and pay-as-you-go browsing, while a bundle pays only for data. Dial *310# and see if your line returns the amount.
If that code does not respond for you, open *301# and look for the balance option inside the menu. The wording of the menu can differ between lines.
How to See Bonus Data and Night Data
Many Glo bundles come with a bonus. The bonus is often valid only at certain hours, usually late night, and it is counted apart from your main data. Your balance message may list both lines, so read it slowly.
- The main figure is data you can use at any time of day.
- The bonus figure may be usable only in the night window, which is usually from midnight to early morning.
- Some bonuses expire sooner than the main data, so use them first.
How to Check Active Subscriptions and Expiry Date
Your balance message normally ends with a date. That date is when the bundle stops working, even if data is left. If you hold two bundles at once, the dates can be different, so check both.
To see what is running on your line, open *301# and look for the subscriptions or my plans option. This is also the place to confirm that an auto-renewal is switched on or off.
How to Read the Balance Message Properly
| You see | It means |
|---|---|
| MB or GB figure | Data left in that wallet |
| A date and time | The moment the wallet expires |
| Two or more lines | Main data plus bonus or night data |
| Zero or no active bundle | You are browsing on airtime, which is costly |
If your balance says zero but the internet still works, your phone may be using airtime at the pay-as-you-go rate. Turn off mobile data until you buy a bundle.
Walking Through the *312# Data Menu
Dial *312# and a list appears. It usually groups plans by period, such as daily, weekly and monthly, with extra groups for special offers. Reply with the number of the group you want, then the number of the exact plan.
Before you confirm, read the price on the last screen. It shows the amount that will be taken from your airtime. If the price looks wrong, cancel by replying with the cancel option or just ending the session.
How Glo Arranges Its Data Prices
Glo sorts its bundles by how long they last. Short bundles are for emergencies, longer ones give far better value per gigabyte. Knowing the families helps you choose without staring at a long list.
| Family | Typical use | Good for |
|---|---|---|
| Daily and 2-day | Small tasks | Messages, quick searches, a map |
| Weekly | Light to medium use | Students and workers who top up each week |
| Monthly | Steady use | Social media, video calls and normal browsing |
| Mega and long plans | Heavy use | Hotspot, MiFi, family sharing and work |
Daily Bundles: What to Expect
The smallest daily bundles start at about ₦50 and give a few dozen megabytes. Around ₦100 you get roughly a hundred megabytes for a day, and about ₦200 gives a little more for two days. These are fine for WhatsApp text and light use.
They are poor value for video. A few minutes of streaming can finish a daily bundle, so use them only when you need a quick top-up.
Weekly Bundles: What to Expect
Around ₦500 a week buys about one and a half gigabytes. At about ₦1,000 you can expect three to four gigabytes, and near ₦1,500 about six to seven gigabytes. Weekly plans often carry the best data for the money among the short plans.
They suit people who budget week by week. If your pay or allowance comes weekly, this family fits your life.
Monthly Bundles: What to Expect
A monthly bundle trades size for time. Around ₦1,000 gives a few gigabytes for thirty days, and roughly ₦2,000 gives about six gigabytes. At ₦10,000 you can expect around forty gigabytes, and near ₦15,000 about sixty-four gigabytes.
Monthly bundles often include night bonus data. If you download big files at night, that bonus can double the usefulness of the plan.
Mega and Long-Validity Plans
Mega plans go from the tens of gigabytes up to a full terabyte over many months. They are made for MiFi devices, routers and busy homes. The price per gigabyte falls as the plan gets bigger, but only if you will truly use the data.
Do not buy a large plan to save money unless you use at least two thirds of it before it expires. Unused data is wasted money.
Understanding Validity
Validity is the number of days a bundle lives. A seven day bundle bought on Monday at noon stops next Monday at noon. When it stops, any leftover data is lost unless the bundle rolls over.
Rollover rules can change, and they usually apply only if you renew the same plan before it ends. Check the rules shown for the plan in the menu before you count on it.
How Night Data Works
Night data is a separate wallet that works inside a fixed window, normally from midnight to about five in the morning. Outside that window the wallet does not spend, and the main wallet takes over.
- Schedule big downloads and app updates for the night window.
- Keep Wi-Fi off and mobile data on, or the phone may use a different connection.
- Remember that night data cannot be used during the day.
Compare Plans by Price per Gigabyte
Divide the price by the data. If ₦500 buys about 1.5GB, each gigabyte costs near ₦333. If ₦10,000 buys about 42GB, each gigabyte costs near ₦238. The larger plan is cheaper per gigabyte, but only wins if you can use it in time.
| Example plan | Rough price per GB |
|---|---|
| ₦500 weekly, about 1.5GB | About ₦333 |
| ₦1,000 weekly, about 3.5GB | About ₦285 |
| ₦10,000 monthly, about 42GB | About ₦238 |
| ₦15,000 monthly, about 64GB | About ₦234 |
How to Buy a Bundle Step by Step
| 1 | Check your airtime balance first so you know you can pay. |
| 2 | Dial *312#. |
| 3 | Pick the period: daily, weekly, monthly or special. |
| 4 | Choose the exact plan and read the price. |
| 5 | Confirm and wait for the SMS that says the bundle is active. |
| 6 | Dial *323# to see that the new data has arrived. |
Buying Data Through the Glo Cafe App
The Glo Cafe app lists every plan with its price and validity on one screen, so you do not need to scroll through menus. It also shows app-only offers from time to time.
You log in with your Glo number and pay from airtime or another method the app offers. The app needs internet to open, so use a small bundle first if your data has run out.
Auto-Renewal: Check Before You Confirm
Some plans can renew by themselves when they end. That is handy if you always want the same plan, but it can drain your airtime when you are not ready. Look at the confirmation screen for any renewal option.
If you do not want repeat charges, turn off renewal from the self-service menu at *301#, or pick the one-time option when you buy.
Common Problems and Quick Fixes
Check that you typed the star and hash correctly, then try again in a minute. If it keeps failing, use the Glo Cafe app instead.
Wait a few minutes and dial the balance code. If it is still missing, note the time and amount and report it to customer care.
Background apps and video auto-play are usual causes. Turn off auto-update and set video quality to low.
Look at the price before confirming. If it happened already, contact customer care quickly, since a wrong purchase is hard to undo later.
Tips to Make Your Data Last Longer
- Switch off auto-play in WhatsApp, Instagram and Facebook.
- Download big files on Wi-Fi when you can.
- Turn off background data for apps you rarely open.
- Use data saver mode on your phone and browser.
- Check your balance once a day so you spot sudden drops early.
Which Plan Is Right for You
| If you are | Start with |
|---|---|
| A light user who only chats | A daily or small weekly bundle |
| A student or office worker | A weekly or small monthly bundle |
| A heavy user with video and calls | A mid-size monthly bundle with night bonus |
| Sharing a hotspot or MiFi | A mega plan sized to your real use |
Questions People Ask
Dial *312# and choose a bundle from the list.
Dial *323#. If that fails, try *127*0#.
No. Night data works only inside its own time window.
Validity is a time limit. When the days end, the leftover data goes too unless the plan allows rollover.
No. Glo can change prices and bonuses, so always read the price on the final screen before you confirm.
Beware of Fake Codes and Messages
Scammers like to send texts that promise free data if you dial a strange code or click a link. Real Glo codes start with a star and end with a hash, and they never ask for your PIN, your bank card or a password.
- Do not dial a code you received from an unknown number.
- Do not share your SIM details, even with someone who says they work for the network.
- If an offer sounds too good, check it in the Glo Cafe app or at *301# first.
Best Times to Check Your Balance
The best habit is a quick check each morning and again before any big download. A morning check tells you whether yesterday’s usage was normal. A pre-download check stops you from starting a large file with too little data.
Also check right after buying a bundle. If the new data did not arrive, you can report it at once while the details are fresh, and customer care can trace it much faster.
Keeping a Simple Data Diary
If your data always seems to vanish, write down your balance at the same time for one week. After seven days you will see which days cost the most. Often one app, such as video or app updates, is the culprit, and you can fix it with one setting.
Final Thoughts
Three habits keep you in control: check your balance often, read the price before you confirm, and match the plan to the way you really use data. With the codes above you can do all three in under a minute, even with zero data on your phone.
