Making an emergency call
In the event of an emergency, you can make emergency calls from your phone, even without a
SIM card. However, you must be in an area with cellular coverage.

Enter the emergency number for your location in the dialer, and then touch .
If you are in an area with good cellular reception, your phone will automatically obtain your
location and display it on the screen.
The ability to make emergency calls can depend on local regulations and carriers in your
area. Poor network coverage or environmental interference may prevent your call from being
connected. Never rely solely on your phone for essential communication during
emergencies.

roaming service.
