We ship our tracking devices with charge in them so you can see the unit on its journey to your door by utilizing the tracking panel http://www.mytrackingpanel.com/BLUHUSKI/ or one of our smart phone apps. Upon arrival we recommend you give your new Bluhuski tracking device a full charge. The Bluhuski tracking device will have 100 Position credits and these are used when the tracker moves, using 1 credit every time the unit reports, if you ask the unit to report every 5 minutes for example you will use 12 positions in 1 hour. The unit will also have 25 SIM credits, they allow you to send COMMANDS to the unit, such as when you change the reporting time or you program the tracking panel to alert you via text message. You can either opt for buying positions and SIM credits as required or take advantage of our UNLIMITED plans that can be bought as 1 month, 3 months, 6 months or for best value 12 months, our UNLIMITED plans give both positions and SIM credits.
