A growing segment of the cell phone market is the 8- to 12-year-old age group. Approximately 41 percent of kids in this age group have a cell phone in the United States, according to an MSNBC article citing the Yankee Group.Though some parents might feel that kids at this age have no business owning a cell phone, one way to quell a safety concern is to add a GPS personal locator service.While various hardware devices are available for GPS tracking, the service can also come directly from your cell phone carrier without the need for additional equipment.Once you have a cell phone that already has embedded GPS technology, you just need software to go with it. You can track your kids between school and home or verify their location at the house of a friend.
Sprint Family Locator
One option available to parents is Sprint Family Locator.
 For $5 a month (with the first 15 days free), parents can see the 
real-time locations of four phones on interactive satellite maps from 
any PC or Web-enabled mobile phone.The service offers unlimited location
 checks as well as Safety Checks. With Sprint, a Safety Check will text 
you when your kids reach certain places based on pre-configured time and
 location settings.As for location accuracy, Sprint says: “You will 
always get the best possible location fix given the conditions. When 
locating phones, Sprint Family Locator will [generally] produce location
 accuracies anywhere between a few yards and a few hundred yards.”Sprint
 notes the following conditions that can yield inaccurate location data:
- The phone is deep inside a building or car.
 - The phone is surrounded by tall buildings, hills, canyons or trees.
 - The phone is near large, reflective surfaces (i.e. lakes or ponds).
 - The phone is powered off. The phone must be powered on.
 - The phone’s battery has run out.
 - The phone isn’t in a Sprint network coverage area.
 
Sprint Family Locator supports all Sprint and Nextel phones with 
embedded GPS technology. A video demonstration of the service can be watched here.
Kajeet GPS Locator
While Sprint is a major cell phone carrier for all kinds of consumers, Kajeet is in business to specifically target parents who want an array of kid-friendly wireless options.The
 Kajeet optional GPS phone locator, though, costs twice as much as with 
Sprint. After your first month for free, the Kajeet feature costs $9.99 
per month. Along with locating a phone for your kids, you can even set 
automatic check-ins with Kajeet.Kajeet allows parents to check phone 
locations online. You can also get automatic emails with phone locations
 at specific times of the day. While parents can use GPS tracking to 
ensure safety for their kids, they can also track elderly parents and 
their own siblings.
GPS Tracking at Verizon Wireless, Alltel Wireless
Verizon Wireless and Alltel Wireless offer similar GPS services for 
$9.99 per month. Chaperone 2.0 from Verizon Wireless works in 
conjunction with VZ Navigator (the carrier’s GPS service) on up to four 
cell phones. Alltel’s service is called the Alltel Family Finder.The GPS
 tracker at Verizon Wireless even allows parents to set “Child Zones” as
 geographical boxes around places (i.e. a friend’s house). Parents will 
receive a text message alert when their child enters and leaves a safe 
zone.In conjunction with the National Sex Offender Registry, Sprint even offers a free service called Family Watchdog. This service sends a text message to parents if a registered sex offender moves into your neighborhood.
