Glo Airtime Balance Not Showing: Fixes
You dial the balance code and get a blank screen, an error, or a figure you do not believe. Airtime problems feel urgent because you may need to call or buy data right now.
The good news is that a missing airtime balance is usually a display or network issue, not stolen credit. Use the checks below from the quickest to the most thorough.
First, the codes that show airtime
- *310# is the main airtime balance code on Glo.
- *124# is the original Glo airtime code and still answers on many lines.
- Glo Café app shows airtime, data and bonus balances on the dashboard.
- Call 121 lets an agent confirm the balance after verification.
Quick fix checklist
| 1 | Dial *310# and wait at least 30 seconds. |
| 2 | If it fails, dial *124#. |
| 3 | Turn airplane mode on for ten seconds, off again, and retry. |
| 4 | Restart the phone and try once more. |
| 5 | Move to a place with a stronger signal. |
| 6 | Check the Glo Café app for the same balance. |
Why the balance may not show
| Cause | What you see | What to do |
|---|---|---|
| Network congestion | Timeout or no reply | Wait and retry in a few minutes |
| Weak signal | Connection problem message | Move or restart the phone |
| Wrong SIM slot | Code works on the other SIM | Dial from the Glo SIM line |
| Barred or inactive line | Services refuse to respond | Call 121 to check line status |
| Recent recharge still processing | Balance unchanged | Wait ten minutes and check again |
Dual SIM phones
On a dual SIM phone, USSD sometimes goes out on the wrong SIM. Open your phone’s SIM settings, pick the Glo SIM as the call or USSD SIM for this session, then dial again. This one small change fixes many cases.
When the balance shows but looks wrong
A lower balance than expected often comes from a renewed data bundle, a value added service or a normal call. Check your active data plan with *323#. If a bundle renewed on its own, you may want to switch off auto-renewal.
After a recharge
If you just loaded a recharge card, enter the PIN carefully with the recharge code and look for the confirmation message. If there is no confirmation and no balance change after ten minutes, keep the card or receipt details and call 121.
Common problems
The session closed early. Redial and keep the screen open until the reply arrives.
This is a temporary network state. Try again later or use the app.
Do not recharge again yet. Wait, recheck, then contact 121 with your recharge details.
Check data renewals, calls and services. Review recent charges in the app.
Questions people ask
Airtime balance codes are normally free. Confirm on your own line if unsure.
No. Codes only work on the Glo line.
What to tell Glo support
Say which code you used, what reply you received, when the problem began and when you last recharged. Short, clear details help the agent trace it quickly.
Check these settings on your phone
- Make sure the Glo SIM is enabled in SIM settings.
- Set the Glo SIM as the default for calls while you check.
- Turn off call barring or any app that blocks USSD dialogs.
- Update the phone software if the dialer behaves strangely.
- Try dialling from the default phone app, not a third party dialler.
How to avoid losing airtime without noticing
Airtime shrinks quietly for a few reasons. A data bundle may renew automatically, a service you forgot may charge a small fee, or a call may run longer than you thought. Make a habit of checking your balance after any call that felt long and after any data purchase.
- Check *310# before and after buying a bundle.
- Review services under the self-service menu at *301#.
- Stop auto-renewal if you want to decide each purchase yourself.
- Keep a small reserve so a failed check does not leave you stranded.
Always keep the recharge card or receipt until the balance is confirmed. It is your proof if you need to contact support.
Using the app when USSD keeps failing
The Glo Café app does not depend on USSD sessions. Log in with your Glo number, open the dashboard and read the balances. If the app also shows nothing, the problem is probably the line or the network, and a call to 121 is the next step.
Final advice
Start with *310#, switch to *124# or the app if it fails, and fix the SIM setting on a dual SIM phone. If nothing works, call 121 with your details ready.
