What to do if your mobile is lost or stolen

Business Telephony
In the Customer Centre, the number for the Business Telepony app must be deactivated immediately.
The employee can then be invited to use the app again.

Mobile number / Contract
If your smartphone has been stolen or lost, you must inform your network provider so the NATEL® number (SIM card) can be blocked (e.g. Swisscom 0800 055 055).


Using the Business Telephony app/client via public networks, non-Swisscom networks or abroad can increase the risk of calls being tapped by unauthorised third parties.

Emergency calls

Emergency calls are always directed to the relevant emergency services where your company is based. The same applies to the Business Telephony app/client, which can be used away from the company premises. Use of the Business Telephony app/client for emergency calls away from the company premises is therefore strongly discouraged. As an exception, if the Business Telephony app/client is used with a mobile device (smartphone), the call is localised via the mobile network and SIM card if the mobile device contains a SIM card configured for voice telephony and if the emergency number 112 is dialled.
