Net calls
With the net call service (network service), you can make and receive calls over the internet.
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.
VoIP (voice over internet protocol) technology is a set of protocols that facilitate phone calls over an IP network, such as the
internet. VoIP phone calls can be established between computers, between mobile phones, and between a VoIP device and a
traditional telephone. To make or receive a VoIP call, your device must be within WLAN coverage, for example.
The availability of the net call service may vary according to your country or sales area.
