Enhanced 911 (E911) Information
This phone features an embedded Global Positioning System
(GPS) chip necessary for utilizing E911 emergency location
services where available.
When you place an emergency 911 call, the GPS feature of
your phone seeks information to calculate your approximate
location. Depending on several variables, including
availability and access to satellite signals, it may take up to
30 seconds or more to determine and report your
approximate location.
IMPORTANT Always report your location to the 911 operator when
placing an emergency call.
Some designated
emergency call takers, known as Public Safety
Answering Points (PSAPs) may not be equipped to
receive GPS location information from your phone.
