The transfer is transparent to you. No installation is needed. No change of your phone number. Your existing line will move to Télésonique. The only difference, you will pay half of the calling rates that you pay to Swisscom.
In addition, you will receive a transparent invoice detailing all your calling consumption at no extra charge. You will receive one invoice from us, for services offered by Télésonique like mobile, internet, etc. We include all of your services and consumption in one informative and transparent invoice.
This service is referred to in the telecom industry as “ULL” for Un-bundled Local Loop, which simply means the end of Swisscom monopoly on the last mile of the telecom fixed network.
