What Is the USSD Codes To Check Glo Night Data Balance Separately? *312# Guide for 2026
If you buy Glo bundles that include night data, you need to know how much of that night pool is left, separate from your daytime balance. Otherwise you can finish the evening believing you have gigabytes to spare when most of them are night data that you can only touch after midnight.
This guide shows how to check your night data on its own, how to read the result and how to plan around the 12am to 5am window. The data menu code *312# is where you buy night bundles, and the balance checks sit right beside it.
What night data is
Night data is the part of a bundle that works only from 12am to 5am. It is counted inside the total size listed on the menu. A bundle of about 42GB at last check held roughly 38GB any-time and 4GB night, so the headline overstates what you can use during the day.
How to see the night balance
| 1 | Dial *323# to see your data balance and expiry. |
| 2 | Look for a separate figure for night data in the reply. |
| 3 | If the reply gives only a total, open the Glo Café app and look at the bundle detail. |
| 4 | Text INFO to 312 for a message with balance and expiry if you prefer SMS. |
USSD replies are short. The Glo Café app lays out any-time and night balances separately, which makes it the clearest tool for this check.
How to buy a night bundle with *312#
| 1 | Dial *312#. |
| 2 | Open the night section of the menu. |

Reading the numbers
| Figure | Meaning |
|---|---|
| Total data | Everything in the bundle, including night data |
| Any-time data | What you can use at all hours |
| Night data | What you can use only between 12am and 5am |
| Expiry | When the whole bundle ends, night portion included |
Planning around the window
- Queue large downloads and updates to start just after midnight.
- Schedule cloud backups for the night window.
- Check the night balance in the evening so you know what is available.
- Do not count night data when planning your daytime use.
What happens at 5am
When the clock passes 5am, night data stops being usable and any remaining usage is taken from your any-time balance. A download that runs past 5am therefore switches to your daytime data. Time your big downloads to finish before the window closes, or pause them and resume the next night.
Does unused night data carry over
Night data belongs to its bundle, so it follows the bundle’s expiry. Renew the same bundle before it ends and unused data can carry over. It does not turn into daytime data.
Common problems
Confirm the time is inside 12am to 5am and that your phone clock and time zone are correct.
Open the Glo Café app for the split.
A single large update can use gigabytes. Check which downloads ran overnight.
A simple evening routine
- Around bedtime, dial *323# and note your night balance.
- Start the large downloads you queued earlier.
- In the morning, check what was used and what remains.
- Adjust the next night’s plan based on what you learned.
After a week of this, you will know exactly how much night data your habits use and whether your next purchase should include more or less of it. Buying a plan with a big night portion only makes sense if you actually use the pool, and the numbers from this routine will tell you.

If night data keeps going unused, it is a sign you may be paying for a pool you do not need. In that case, choose bundles with less or no night portion next time and put the difference into more any-time data.
Write the result of each morning check in a phone note for a week. Seven short lines will show whether you spend more night data than you buy, and tell you exactly how much night data your next bundle needs.
Final word
Treat night data as a separate pool. Check it each evening, plan your big downloads for the window and never count it toward your daytime needs.
