Cell Phone Technology

Nearly all new cellular phones sold have some built-in GPS receiving capability. Those that do not can request the service from their cellular phone provider.

• GPS cell phones may need a clear line of sight with the sky in order to establish a location and may not work properly indoors.
• Be sure your cellular phone stays charged. Because the phone is sending its location every two minutes, it is using more battery power than it typically does and will need to be charged more frequently.
• GPS cell phones with view screens can often display turn-by-turn direction as well as announce them through the phone’s speaker. These services are available for a monthly fee and use databases of maps to provide directions.
