Re: Why can't I locate my Son's HTC ONE X phone using AT&T Family Map?
AT&T Family Map uses several different techniques to locate a phone. However, despite all of these techniques, poor geographic conditions and phone limitations can still result in inaccurate locations.
The phone that you are trying to locate is deep inside a building or car.
The phone is surrounded by tall buildings, hills, or trees.
The phone is powered off.
The phone's battery has run out.
The phone is not in AT&T network coverage. (AT&T FamilyMap does not work in Former Cell One or Centennial networks).
If this is not a problem for you, I recommend contacting your AT&T Customer Care and Speaking with Technical Support. Your device is probably not compatible with the feature; updating to the latest Operating System may help.
