No monthly payments
TrackStep does not use any server. All the communications are done directly from your Android phone to your GPS tracker and back, using SMS messages. That way you do not have to pay any monthly fees for any service.
You just need a SIM card for the GPS Tracker and another for your Android Phone. You choose the mobile operator you want to work with, you choose the contract you like (or prepaid) and you pick the use you want to give to the tracker.
You will just pay when you use the devices and nothing else.
