Dial *323# on your Glo line to check the main data balance and expiry. This guide focuses on interpreting multiple Glo data buckets, checking an hourly or bonus allowance, handling a missing purchase and choosing *312# only when you actually want to buy or manage a plan.

Dial *323# from the Glo SIM whose data you want to inspect. Glo’s official data FAQ also identifies *312# as a route that can expose bundle information, while *301# opens Glo Café self-service. For a quick balance check, begin with *323#.

The direct answer

  1. Turn off any active USSD window.
  2. Choose the Glo line on a dual-SIM phone.
  3. Dial *323#.
  4. Read every allowance and expiry date shown.
  5. Save the result if you are investigating a disputed deduction.

Why Glo may show more than one balance

A Glo line can hold a main bundle alongside bonus, social, gifted or time-limited allowances. Those buckets may not expire together and may not apply to the same type of traffic. A large displayed total can therefore be less useful than the breakdown. Note the name of each bucket, its remaining allowance and its expiry.

Glo’s official FAQ for hourly data says a user can check through *312#, *323# or the *301# Glo Café route. It also explains that multiple hourly bundles are used according to which one expires first. That detail matters when the balance falls from a bucket you did not expect.

Checking a Glo purchase that has not appeared

Do not buy the same plan again immediately. Check *323#, wait for the confirmation SMS and inspect whether a new bucket was added with its own name. Save the payment reference, time, amount and Glo number. If airtime was deducted, include the before-and-after airtime balance when reporting the issue.

If you paid through a bank or wallet, a debit alert only proves that the payment side recorded a debit. It does not prove that Glo provisioned the bundle. Contact the payment provider and Glo using the same evidence so each can trace its side of the transaction.

Buying or changing a Glo plan

Dial *312# to open the current data-plan menu. Choose by allowance, validity and renewal—not merely by the first price displayed. Glo publishes provider-specific bundles, including products with daily allocations, so read whether the offer is one-time, recurring or split into daily portions.

This guide avoids copying a complete price catalogue because prices and promotional allowances change. The live menu and Glo’s official plan pages should control a purchase made today. After confirmation, return to *323# and verify what was credited.

Useful Glo codes for related problems

  • *310# checks the airtime balance.
  • *311*PIN# loads a recharge voucher.
  • *303# opens borrow services when the line is eligible.
  • *305# manages or stops value-added services.
  • *321# opens sharing services.
  • 300 reaches customer care.
  • *996# opens NIN-SIM services.

These harmonised entry points are not a promise that every offer is available to every Glo line. Eligibility, bundle names and menu order remain controlled by Glo.

Fix a Glo balance code that does not respond

Confirm that the Glo line can make a voice call, because USSD uses the mobile network rather than your Wi-Fi connection. Manually select Glo, re-enter the full code and retry once in an area with stronger signal. If the session repeatedly closes, use Glo Café or customer care instead of making repeated purchases.

When the result appears wrong, capture the screen without exposing a recharge PIN, NIN or another private identifier. Give support the affected number, time and plan name. No genuine support process requires you to disclose a banking PIN or OTP.
