A call to a number starting with 0900, 0901 or 0906 (combined designation: 090x) usually costs more than a phone call to a friend, a customer or a relative. In the case of monthly subscriptions with inclusive minutes, the cost of these calls is usually additional to the subscription price. Such numbers allow you to have a conversation as well as provide you with a service, which is charged directly to you on your telephone bill. The price of a call to one of these added-value services may cost several Swiss francs per call and per minute. Calls to such premium-rate numbers and the use of such services may therefore inflate your telephone bill. Caution is advised.
