Last checked: 26 June 2026. Mobile-network menus, USSD codes, app paths, and content-service controls can change. Before publishing or relying on an exact menu option, verify it again with the relevant provider’s current support page, app, or customer care.
If you have no active subscriptions but airtime disappearing, the problem may not be the normal subscription list. Airtime can still be used by background mobile data, out-of-bundle data, premium-rated SMS, direct carrier billing, a recurring bundle, a value-added service, airtime transfers, USSD competition entries, or a content service that is not showing in the first menu you checked. WASPA lists unexpected data charges, WASP services, premium-rated SMS, airtime transfers, and some USSD usage as possible reasons for disappearing airtime. (WASPA)
The safest first step is to stop new usage, check the most likely billing routes, and keep evidence before escalating.
Quick Fixes to Try First
Use these checks before buying more airtime or repeatedly trying cancellation codes.
| Problem | What to check first | What to do next |
|---|---|---|
| Airtime drops even though no subscriptions show | Background data or out-of-bundle data | Turn off mobile data, check your data balance, then check again |
| Airtime deducted without subscription shown | Direct carrier billing, app-store billing, or content billing | Check your provider app and see direct carrier billing South Africa |
| You received a “welcome”, “charge”, “STOP”, or shortcode SMS | WASP or premium-rated service | Keep the SMS and use the provider’s content-service cancellation route |
| The USSD menu says no active services | The charge may be from another billing category | Ask customer care for the exact charge name, company, time, and amount |
| The cancellation code fails or times out | Network, SIM, account, or menu issue | Follow USSD code not working before retrying |
Start here:
- Turn off mobile data. This stops apps from using airtime while you investigate.
- Take a screenshot of your airtime balance.
- Check your data balance and bundle balance. If your bundle is finished, mobile data may be using airtime.
- Check your SMS inbox. Look for welcome messages, shortcodes, premium SMS replies, content-service names, or cancellation confirmations.
- Check content services through your provider’s official route.
- Check app-store or direct carrier billing. A payment can sometimes be charged through your mobile number rather than a bank card.
- Contact customer care if charges continue. Ask what exactly deducted the airtime and request a reference number.
Do not assume a refund is automatic. First confirm what caused the deduction, then ask the provider whether cancellation, blocking, investigation, or reversal is available.
Why This USSD Problem Happens
“No active subscriptions” usually means that the menu you checked did not find an active subscription in that specific category. It does not always mean that nothing can deduct airtime.
Background data can use airtime
If mobile data is on and your bundle has expired or run out, apps may use airtime in the background. Messaging apps, cloud backups, email, maps, social apps, app-store updates, and phone updates can all use data without you actively opening them.
WASPA recommends checking whether the issue is data-related and switching off data services or background app data that you do not need. (WASPA)
Direct carrier billing may not look like a normal subscription
Direct carrier billing allows certain digital services to be charged to your mobile account or deducted from prepaid airtime. Vodacom says customers can use a Contract, Top Up, or Prepaid number to pay for content services, and prepaid payment may be deducted from airtime. (Vodacom)
This can include entertainment, games, app-store purchases, subscriptions, or other digital content. If you use mobile billing for apps or streaming services, read direct carrier billing South Africa before assuming it is a hidden WASP.
WASP services may need a different cancellation route
A WASP is a Wireless Application Service Provider that provides or distributes mobile content and services such as SMS alerts, games, competitions, or bulk messaging. (WASPA)
If you receive a subscription SMS, welcome message, or premium-content message, do not ignore it. Keep the message, use the official cancellation route, and ask your network to confirm the company billing you.
Premium-rated SMS or USSD can create charges
Some charges come from premium-rated SMS numbers, competition entries, voting services, content shortcodes, or USSD services. These may not always appear in the same place as ordinary subscription services. WASPA specifically lists premium-rated SMS and certain USSD usage as possible causes of disappearing airtime. (WASPA)
Recurring bundles or value-added services can renew
A daily bundle, recurring bundle, caller tune, add-on service, insurance-type value-added service, or network promotion may renew automatically. These are not always labelled as WASP subscriptions.
Check your provider app for active bundles, value-added services, recurring purchases, and usage history.
Billing can be delayed
Airtime may drop after the actual usage happened. A data session, app charge, premium SMS, or content-service charge may reflect later, making it look like airtime disappeared while the phone was idle.
The wrong SIM may be checked
If your phone has two SIM cards, confirm that you are checking the same SIM that is losing airtime. Also check whether the charge is on a prepaid, Top Up, contract, or linked account.
Provider-Specific Checks
Use only the route for your network. Dial USSD codes from the SIM that is losing airtime. If the exact menu shown below does not appear, stop and use the provider app or customer care instead.
| Provider | What to check | Verified route to check before publishing |
|---|---|---|
| Vodacom | WASP, Add to Bill, V-Live, and content services | Vodacom lists *135*997# as a route to manage or unsubscribe from WASP, add-to-bill, or V-Live content services. Vodacom also lists My VodaPay and TOBi as management routes. (Vodacom) |
| MTN | Content and subscription services | MTN says users can view and cancel content and subscription services by dialling *155#. (MTN) |
| Cell C | Existing and future content billing | WASPA lists *133*1# as the Cell C USSD string to block existing and future content billing. Verify inside Cell C’s current menu before publishing. (WASPA) |
| Telkom | Direct carrier billing and content services | Telkom says subscriptions can be managed through the Telkom Mobile App or Self-Service portal by selecting the product, mobile number, subscription, and content services. (Telkom) |

Step-by-Step: What To Do If Airtime Keeps Disappearing
Step 1: Stop possible new deductions
Turn off mobile data first. If you are on prepaid, avoid loading a large amount of airtime until you know what caused the deduction.
Also pause anything that may use mobile billing:
- App-store purchases.
- In-app purchases.
- Streaming subscriptions.
- Games.
- Premium SMS services.
- Competition entries.
- Unknown shortcodes.
- Daily recurring bundles.
Step 2: Check your balance and usage
Check:
- Airtime balance.
- Data balance.
- Active bundles.
- Recurring bundles.
- SMS balance, if relevant.
- Recent usage history in the provider app.
- Recent SMS messages from shortcodes or content services.
Take screenshots before and after each check. This helps if you need to escalate the query.
Step 3: Check content services
Use your provider’s official content-service route. What you should see depends on the network, but you are generally looking for:
- A list of active content services.
- A “no active subscriptions” message.
- An option to stop one service.
- An option to stop all services.
- An option to block future content billing, if available.
If a service appears, cancel it and save the confirmation message. If no services appear but airtime still drops, continue to the next step.
Step 4: Check direct carrier billing
If you use your mobile number for app payments, games, streaming, or digital subscriptions, check the provider app and the app-store account.
Look for billing labels such as:
- Content services.
- Add to bill.
- Direct carrier billing.
- Mobile payment.
- App-store subscription.
- Digital content.
- Premium content.
Vodacom’s Add to Bill page says content-service payments can be added to a Vodacom account or deducted from prepaid airtime, and Telkom provides a specific direct-carrier-billing subscription management route through its app or Self-Service portal. (Vodacom)
Step 5: Contact customer care with the right questions
If you still have no active subscriptions but airtime gone, contact your mobile provider. Do not simply ask, “Why is my airtime disappearing?” Ask for the billing detail.
Ask:
- What services am I being charged for?
- Is it data, a WASP service, direct carrier billing, premium SMS, a recurring bundle, airtime transfer, or something else?
- What is the exact name of the service?
- What company is billing me?
- What date and time did each charge happen?
- What amount was deducted?
- Can you cancel the service?
- Can you block future content-service or premium-rated charges?
- Can I have a reference number?
WASPA recommends asking the mobile operator what services are being charged, whether they are WASP services, data services, or something else, and whether a company is billing the user for subscription services. (WASPA)
Step 6: Escalate only after you have evidence
If the issue is a WASP or content-service billing problem, WASPA says users can contact WASPA if the mobile operator is unable to assist. (WASPA)
If the issue is a telecommunications billing complaint against a licensed service provider, ICASA says users must first lodge a complaint with the service provider, get a reference number, and allow 14 working days for resolution before referring the complaint to ICASA, unless the provider’s response is unsatisfactory. (icasa.org.za)
ICASA also notes that content-services billing, SMS spam, and wireless application services should be directed to WASPA rather than ICASA. (icasa.org.za)
Common Errors and What They Mean
| Error or result | What it may mean | What to do |
|---|---|---|
| “No active subscriptions” | No subscription found in that menu | Check data, direct carrier billing, recurring bundles, and usage history |
| “Service unavailable” | USSD platform or network issue | Retry later or use the app |
| “Request timed out” | Signal, SIM, or USSD session issue | Move to better signal and retry once |
| “Invalid option” | Menu path changed | Stop and verify the current provider route |
| Airtime still drops after cancellation | Another billing route may be active | Contact customer care with screenshots and ask for itemised charge details |
| You receive more shortcode SMS messages | Possible premium or content-service route | Save messages and report through provider or WASPA if needed |
When to Use an App, Website, or Customer Care Instead
Use an app, website, or customer-care route when USSD does not give a clear answer.
Use the provider app if:
- USSD keeps timing out.
- The menu does not show content services.
- You need usage history.
- You need to see recurring bundles.
- You suspect app-store or direct carrier billing.
- You want to block future content services, where available.
Use customer care if:
- Airtime keeps disappearing after cancellation.
- The app and USSD both show no active services.
- You need the billing company’s name.
- You need a reference number.
- You want the provider to block future content or premium-rated charges.
- You want to query a possible refund or reversal.
Use WASPA if:
- The charge appears to be a WASP or content-service issue.
- The provider cannot identify or stop the service.
- You need to report unwanted billing, SMS spam, or suspicious content-service activity.
Use ICASA if:
- The issue is a telecommunications service-provider complaint within ICASA’s mandate.
- You already complained to the provider.
- You received a reference number.
- The provider did not resolve the complaint within 14 working days, or you are not satisfied with the response. (icasa.org.za)
Safety Notes
Never share these through suspicious links, social media inboxes, or SMS replies:
- OTPs.
- Banking passwords.
- SIM PINs.
- App passwords.
- Full card details.
- ID documents.
- Online banking login details.
- One-time approval prompts.
A real cancellation route should not need your banking password or OTP. If a message says you must click a strange link to stop airtime deductions, treat it as suspicious and verify through your provider’s app, website, store, or customer-care channel.
FAQs
Why is no active subscriptions but airtime disappearing happening?
It may be because the deduction is not from the subscription list you checked. Common causes include out-of-bundle data, background app data, direct carrier billing, premium-rated SMS, recurring bundles, airtime transfers, USSD competition entries, or delayed billing.
Does this mean the code has changed?
Not always. The code may still work, but the charge may be coming from another billing route. It can also mean the USSD menu is unavailable, your SIM has a restriction, or the provider changed the menu path. Verify current codes and menu options before publishing them.
Can I fix it without calling customer care?
Sometimes. Turn off mobile data, check balances, check content services, check direct carrier billing, and cancel or block services through your provider’s official route. If airtime still disappears, customer care is usually needed because they can see the billing description.
Should I use the app instead of USSD?
Use the app if USSD fails, times out, or says no active subscriptions while airtime continues to drop. Provider apps often show usage history, recurring bundles, subscriptions, content services, and account settings more clearly than USSD.
How can users check whether no active subscriptions but airtime disappearing is active?
Check the airtime balance, data balance, active bundles, content-service menu, provider app, SMS inbox, and direct carrier billing settings. If nothing appears, ask the provider for the exact charge description.
What should users do if airtime is still disappearing after cancellation?
Keep the cancellation confirmation, screenshot your balance, turn off mobile data, and contact customer care. Ask for the service name, billing company, charge date, charge amount, and a reference number. Do not assume a refund is guaranteed.
Can users block future content-service subscriptions?
Some networks provide blocking options. Vodacom lists *135*997#, My VodaPay, and TOBi as routes to manage content services. WASPA lists network-specific routes for Cell C, MTN, Telkom, and Vodacom, but these should be rechecked because menus can change. (Vodacom)
Can users get a refund for unwanted subscription charges?
A refund is not guaranteed. Ask the provider to investigate and confirm whether the charge was valid, accidental, disputed, or reversible. Keep screenshots, SMS messages, cancellation confirmations, and reference numbers.
Where should users report suspicious subscription messages?
Report suspicious WASP billing, SMS spam, or content-service messages through your provider or WASPA. For network billing complaints, start with the provider and get a reference number before escalating through the correct complaints route. Never share OTPs, passwords, SIM PINs, card details, or ID documents through unsafe channels.
