WASP charges are a top reason for unexplained airtime loss. The fix is systematic: identify active paid services, cancel them, and block repeat billing.

Quick Answer

WASP services are recurring paid content subscriptions that can deduct airtime automatically.

Stop them by canceling all unknown paid services and enabling premium-content restrictions.

Then monitor your next recharge cycle to confirm the deductions are gone.

Causes

  • Opt-ins via ads, links, or number-entry promo forms.
  • Premium SMS services billed as value-added content.
  • Legacy subscriptions still active from older campaigns.
  • Multiple low-value services causing repeated small deductions.
  • No premium-content block enabled on the account.

How to Fix

  1. Check active paid services in your operator menu.
  2. Cancel every unknown WASP or premium content entry.
  3. Enable premium-content blocking where available.
  4. Recheck service status after 10 to 15 minutes.
  5. Track deductions for 48 hours and escalate with proof if needed.
