It’s frustrating to check your balance and see that your airtime has dropped, even though you haven’t made any calls, sent any texts, or bought any data. This happens to many people in Nigeria. You might have enough credit one moment, then notice it shrinking for no clear reason.
You’re not imagining things. Hidden subscriptions or small automatic charges often use up your airtime. The good news is you can stop this with a few simple checks and USSD codes. Here’s what’s happening and how to fix it.
Common Reasons Your Airtime Disappears Without Usage
Here are the main reasons this happens in 2026:
- Value Added Services (VAS) or hidden subscriptions are a major cause of airtime loss. These include caller tunes, news alerts, sports tips, games, and ring-back tones. Sometimes, you might accidentally subscribe while downloading a song or browsing. These services often renew daily and can charge ₦30, ₦50, or more without warning.
- Auto-renewal is another cause. Some data or voice plans renew automatically and will use your main airtime if your bundle is finished.
- Background app activity or pay-as-you-go browsing can also use up airtime. If your mobile data is on and apps are running in the background, they might use small amounts of airtime when you don’t have an active bundle.
- Premium SMS or special services can also result in deductions. Sometimes, people accidentally subscribe to paid SMS services or use certain short codes that charge fees.
- Other small deductions can come from USSD banking fees, which are sometimes deducted from your airtime, or from borrowed credit, such as 'Please Call Me' or credit advances.
All networks in Nigeria, including MTN, Airtel, Glo, and 9mobile, offer these services. Subscriptions are not always easy to spot.
How to Check and Stop Unwanted Airtime Deductions
To take back control, check your active subscriptions and cancel any you don’t need. Here’s how to do it for each network:
For MTN:
Dial *305#
This will show your active VAS and subscriptions.
You can unsubscribe from any services you don’t want, or stop all of them at once.
For Glo:
Dial *305# (this works for many Glo users) to view and manage your subscriptions.
