Glo Service Codes: Which Ones Are Still Active?
Search for Glo service codes and you will find lists with dozens of entries. Some work today. Some worked years ago. Some were never official. Dialling the wrong one wastes time, and a few can even change settings on your line.
This guide sorts Glo codes into three groups: codes that are widely active, codes that are older and may still answer, and codes you should test carefully before trusting. Use it as a quick filter before you dial.
If a code is for balance or the data menu, it is almost certainly active. If it promises free data or a secret menu, be suspicious.
Menus change. Read the options on your own screen, and call 121 if a code asks you to pay for something you did not expect.
Codes that are widely active
| Code | Service | Status |
|---|---|---|
| *310# | Airtime balance | Active on current lines |
| *323# | Data balance, plan and expiry | Active |
| *312# | Data bundle menu | Active |
| *301# | Self-service menu | Active |
| *321# | Share data with a Glo number | Active, with limits |
| *303# | Borrow airtime or data | Active for eligible lines |
| *311*PIN# | Recharge card loading | Active |
| *996# | NIN and SIM link status | Active |
| 121 | Customer care | Active |
Older codes that may still answer
Glo has simplified its menus over the years. Some older codes still reply on many lines, often because the network keeps them as shortcuts. They are fine to try, but do not depend on them.
- *124# for airtime balance. It often still works, though *310# is the safer choice.
- *127*0# for data balance. It answers on many lines, while *323# is the main check.
- *777# for an older account menu. Results differ by line.
- Older direct bundle codes that begin with *127*. Many were folded into the *312# menu.
Codes to test before you trust
These appear in guides with little confirmation. Dial them only when you understand the risk, and read every screen.
- *135*8# is said to show your own number. Test it, then rely on another method if it fails.
- *606# and *100*9# are said to show bonus airtime. Results vary by line.
- Codes that promise free data, unlimited browsing or a special bonus. Skip these unless Glo itself has announced them.
How to test any code safely
| 1 | Check your airtime first with *310# so you know the starting point. |
| 2 | Dial the code and read the first screen fully. |
| 3 | Stop if the screen asks you to pay, subscribe or forward calls you did not expect. |
| 4 | Check your airtime again afterwards. |
| 5 | If anything looks wrong, call 121 and describe what you dialled. |
Why codes stop working
- Glo retires a code or replaces it with a menu option.
- The service behind the code is closed.
- Your line is barred, inactive or not linked to a NIN.
- The network is busy and the session times out.
- The phone sends the code on the wrong SIM.
Signs of an unreliable code list
- It promises free data without any detail.
- It lists codes with no explanation of what they do.
- It has no date, or the date is very old.
- It tells you to forward a code to friends.
Common problems
Check the stars and hash, then dial again. If it still fails, the code is likely retired.
Menus change. Pick the closest option and read the confirmation before you accept.
Check the airtime before and after. Call 121 if the charge was not shown on the screen.
Questions people ask
*310#, *323#, *312#, *301# and 121 cover almost everything.
Usually it just fails. The risk comes from unofficial codes that change settings, so avoid those.
Dial *301# and *312#, or open the Glo Café app.
How to keep your own safe list
Open your phone notes and make a short list of the codes you actually use. Add a line about what each one does and the date you last confirmed it worked. When a code fails, cross it out and replace it with the menu route. A list of ten verified codes beats a list of one hundred unverified ones.
| Task | Code you can trust | Backup |
|---|---|---|
| Airtime balance | *310# | *124# or the app |
| Data balance | *323# | *127*0# or SMS |
| Buy data | *312# | Glo Café app |
| Account menu | *301# | Call 121 |
| Check NIN link | *996# | Glo office visit |
What to do if a code changes your settings
If you dial a code and then notice odd behaviour, such as calls not ringing or messages not arriving, note the code and the time. Check the self-service menu for the setting involved, switch it back, and call 121 if you cannot. This is rare with official codes, but it is the reason to read each screen before you reply.
Bottom line
Stick with the short list of widely active codes, treat the older ones as backups, and test the rest with caution. When a code fails, the menu or the app will almost always get you to the same place.
