Losing airtime? If you have an unusually high phone bill, or your air time is disappearing Establish exactly what is causing the problem, it could be: Unexpected data charges (apps running in the background) WASP services (subscription services) Sending lots of SMSes to premium-rated numbers Airtime transfers USSD usage (example, when the user dials *120*123# to enter competitions) Check your SMS history to see if you have messages welcoming you to a subscription service, or reminding you about a service you are subscribed to. Contact your mobile service provider if you need assistance in determining what you are being billed for. Questions you should ask your mobile operator when you contact them What services am I being charged for? Are those WASP services, data services, or something else? Is there a company billing me for subscription services? What is the name of the company or companies billing me? Do you have a phone number for that company? Can you cancel the subscription services for me? If data charges are the problem Make sure you switch off data services on your phone that you don’t need.
