Practical info

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.

Are you shocked by the amount on your mobile telephone bill? Sending and receiving premium-rate SMS or MMS messages might be the cause! SMS and MMS services such as stock market information, sports information, downloading of games, logos and ring tones are more expensive than normal SMS/MMS messages to a friend or relative.

Have you received unsolicited advertising by e-mail, fax, SMS or from automatic calling equipment? Has someone asked you for confidential information by e-mail? Then you are a victim of spamming. Mass sending of advertising without the recipient's consent is banned. You can limit spamming by following a few simple rules and exercising caution.

If you do not want all your calls to go via the same carrier, you have the possibility, before each call, of manually selecting which  company will carry your call and bill you for the price of the call. You will therefore be using the so-called "call-by-call" method.

Unsolicited telemarketing calls remain very common, despite stricter regulations, and are generally considered annoying by those affected. Though complete protection against unwanted telemarketing is impossible, certain measures can nevertheless help to reduce interference to a minimum.

When moving house, telephone customers can keep their old telephone number, even if moving to a different region. However, it is a pre-condition that their provider supports porting of the telephone number.
