Make calls
106
If Internet call is set as the preferred call type, and your
device is connected to an internet call service, calls are
made as internet calls as default.
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 internet 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 internet
call provider's implementation of emergency call
capabilities. Contact your internet call provider to check
the internet telephony emergency call capability.
