Trakbond locator requires a GPS signal to show the accurate location of your loved ones. If you want your locator to work indoors then you’ll have to enable the LBS Positioning feature present in the “Settings” section of the Trakbond app. Though the location-based service (LBS) is not very accurate (accuracy may vary from 50 meters to few 100s of meters or even more), it can show you the approximate location of your loved ones if cellular towers are available nearby.
