As the cell phones are moving into kids’ hands therefore now various GPS locator services are being used by parents to follow their kids by locating their phones while going from home to school, or to friends’ houses.

Many of the wireless carriers have such locator programs, which are usually offered for a fee of about $10 a month. And if you’re not ready to give your child a mobile, there are other devices that provide tracking, but monthly costs are generally higher than for similar cell phone services.

Sprint, Verizon Wireless and Alltel have family locator plans for a monthly charge of $9.99. However AT&T and T-Mobile do not offer such programs.

Verizon Wireless’ Chaperone 2.0 location service works in conjunction with VZ Navigator, the company’s GPS program, on up to four phones.

“Once you locate your child on a mobile device, you can press a button and get turn-by-turn directions to that location,” said Jack McArtney, the company’s associate director of advertising and content standards.

“Child Zone” is one of its salient features, where the Parents can use this feature to set up geographical boundaries around locations, such as a friend’s house or a ball field, and receive a text message alert when their child arrives or leaves that “zone.”

Sprint’s Family Locator and Alltel’s Family Finders programs are similar to Verizon Wireless.
