Sprint has a nifty feature called Sprint Family Locator, and it allows account holders to monitor the real-time location of family members by tracking their phone's Global Positioning System (GPS) system.
Step 1
Visit "sfl.sprintpcs.com" to sign up for Sprint Family Locator service. Enter the primary telephone number on your Sprint account and choose your billing method. The first 15 days are free; as of October 2009, the service is $5 per month thereafter.
