Check each allowance and its expiry
A positive balance can include data you cannot use for ordinary browsing. Airtel’s YouTube Night bonus is for YouTube from midnight to 5am; Glo’s listed night data also runs midnight to 5am. T2’s night allowance runs 11pm to 5:59am, and its social allowance is limited to Facebook, X, Instagram and WhatsApp chat. MTN bundles can have separate expiry dates. Check the main balance and each bonus before buying more.
Get operator help
If self-service does not work, dial 300 from the relevant network or use the operator support page.
If the balance looks wrong

- T2's official pages currently contain a mixture of T2, MyT2, 9mobile and Ig9ite naming, so confirm the branding shown on your SIM or account before continuing.
- Codes and app menus can vary by plan or account. If a method fails, use the operator support route before trying repeated requests.
