Hi,
The main operator in Switzerland (Swisscom) released a new prepaid offer very interesting for travelers in Switzerland :
Calls to all Swiss networks (landline and mobile) : Daily rate CHF 3.- (~EUR 1.96)
Data traffic within Switzerland : Daily rate CHF 4.- (~EUR 2.60)
With this offer you can use a swiss local access number of Betamax to call all around the world for less.
