About internet calls
You can make and receive calls over the internet (network service). Internet call services
may support calls between computers, between mobile devices, and between a VoIP
device and a traditional telephone.
Some internet call service providers allow free internet calls. For availability and
connectivity costs, contact your internet call service provider.
The use of VoIP or other services may be restricted in some countries. For more
information, contact your device retailer, service provider, or local authorities.
To make or receive an internet call, you must be in the service area of a WLAN, and be
signed in to an internet call service.
