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.
