Télésonique was also the first operator to virtually remove the borders between Switzerland and its neighbors, by introducing its “Sans Frontiers” offer (without Borders). With this offer Swiss customers for the first time in history, could call Germany, France, Italy and Austria for the same rate as calling domestically.

Télésonique was also the first operator that introduced competition on international calling rates from mobile. An area that had no competition, as the 3 mobile operators can get away with charging whatever rates they pleased.
