making waves in the telecom market



contributing to the Swiss market liberalization since 1998

Do you realize?


Calling to a mobile phone in North America, Australia or Japan


with Télésonique is less expensive than calling your


next door neighbor on her/his Swiss mobile!! (with you know whom).


 But do not worry,  you can also make calls to


all mobile networks in Switzerland for 50% of the rates of Swisscom®.
