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.
