If you are selling these devices it's important to elucidate how they work to consumers.
These devices will mechanically receive location thanks to satellite signals coming from overhead, but so as to send alerts they need to have a SIM card which is kept charged with credit. One also

needs to be acquainted with map software,eg Google maps, where the trackers' location can be found by typing in the coordinates given by its alerts. The battery also must be kept charged as well!
GPS tracking devices with geo-fence capability will also have their own mapping software which must be used to line up the boundary. This is really easy, but since it varies per device you as the

vendor must be prepared to give some categorical advice so as to offer reasonable customer service.
buyers using GPS tracking devices with geo-fence to keep watch on their youngsters of any age must be conscious of signal radius , battery

charge lifespan and GPS chipset.
If the device's battery is weak then it limits how long the kid can be tracked for and the same can be said for the chipset which is the brain of the gadget. If the device loses the GPS signal you

will not be in a position to track the kid and therefore the chipset's capacity is critical too.
Size is also an argument as it is vital for the device to be subtle or, better, invisible as children and especially teenagers may not welcome being tracked!
If you're a parent who concerns about their children's safety or whereabouts then GPS tracking devices with geo-fence can at last give you the reassurance that you've been searching for, regardless

of whether you're at work or on business in another town!
