"Call & Surf" is PhoneWorld’s low-cost program to get you connected to the internet with voice and data. It is compatible with new VoIP technology. It is only recommended for residences.
Note for ISDN: Call & Surf can still be used. However, if you have a number block of 3 we will maintain the principal number only. Please consult your local electrician for the appropriate wall plugs and handsets.
VDSL is available for residences and business if distance from the next Central is less than 1.200 m. Locations over this limit need to use ADSL 2+ (ie a “naked”), or via fiber optic cable.
VDSL stands for Very high bit-rate Digital Subscriber Line. VDSL operates over the copper wires in your phone line in much the same way that ADSL does, but there are a couple of distinctions. VDSL can achieve incredible speeds, as high as 500 Mbps downstream and 100 Mbps upstream (to home or office)
Switzerland is currently aggressively expanding its fiber optic infrastructure. Fiber is already available in most metropolitan areas. for availability in your area.

PhoneWorld VoIP for business is protecting your internet connection via an integrated LTE modem. (LTE = Long-Term Evolution – a standard for high-speed wireless communication).
The modem achieves theoretical 100 Mbps down- and 50 Mbps upload (via LTE). A PhoneWorld Mobile SIM card is placed into the slot provided. Signal strength can be read on the front panel.
Needless to say, when there is internet failure of the Swiss internet back-bone, PhoneWorld Mobile 4G connects automatically so you will never be without access. When internet is restored, the unit switches back automatically.
The modem is VDSL and FIBER compatible – therefore, no new modem required on a future move to fiber.
