Location was working on my kid's Moto E which has only call/ text and wifi service (no data plan), but lately I can't get a live location and location points are recorded only between midnight and 7 am (totally useless info for us). What can I do? Thanks!
There seems to be some issues with the Mobile Security web site being able to locate a device.
Until these are corrected, if you have another cell phone, you can send the locate command by SMS message. That will trigger the locate function on your child's phone. That location should be available on the web site.
This feature can be used in the way you are asking, but it is not really designed to track your kids. It is designed to be able to find a lost phone.
