Mobile companies have also stepped up the family safety factor with services like the Sprint Family Locator. "Sprint Family Locator is a valuable tool that can help parents and guardians have a better sense of their children's whereabouts when they're apart," said Danny Bowman, vice president of product marketing for Sprint. "This is the latest Sprint innovation that uses GPS technology to improve the way families connect, communicate and locate one another." The same service from AT&T is called FamilyMap. Both companies offer free trials.
