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.
