Did you receive an unexpectedly high phone bill after calling a premium rate number? Some services or advertisements, such as fortune-telling lines, can be accessed via a premium rate number starting with 0903, 0907, or 0909, for instance. These services are often designed to keep you on the line for as long as possible, resulting in a high phone bill later.

Before calling a premium rate number, it's best to check the company's contact information, the actual cost of your call and the terms of service. Be extra cautious when the service is advertised as free!

Do you already have a contract with a company? Its customer service should not require you to call an expensive phone number.
