Our trackers have a GPS chip that collects location data from satellites. In order to then send this data to your phone, it requires a SIM card to connect to the phone network. Our SIMs are low-cost and multi-network, meaning you’ll get coverage wherever you are. You can also choose a plan that suits you. We offer 1, 6, 12 or 24 month plans. Choose whether you require Data or Voice by looking at the options below.
