Internet calls
With the internet call service (network service), you
can make and receive calls over the internet.
Internet calls can be established between
computers, between mobile phones, and between
a VoIP device and a traditional telephone. To make
or receive an internet call, your device must be
connected to an internet call service.
To connect to an internet call service, your device
must be in the coverage of a connection network,
such as a WLAN access point.
Your device supports voice calls over the internet
(net calls). Your device attempts emergency calls
primarily over cellular networks. If an emergency
call using cellular networks is not successful, your
device attempts an emergency call through your net
call provider. Due to the established nature of
cellular telephony, you should use cellular networks
for emergency calls, if possible. If you have cellular
network coverage available, make sure that your

cellular phone is switched on and ready to make
calls before you attempt an emergency call. The
capability for an emergency call using internet
telephony depends on the availability of a WLAN
network and your net call provider's
implementation of emergency call capabilities.
Contact your net call provider to check the internet
telephony emergency call capability.
