Why do I need a SIM card ?


The GPS tracker knows its position on the earth by monitoring satellites. So you know where it is, the tracker uses the mobile phone network communicate with the website and your mobile phone.

Can the tracker tell me when the PrePay SIM is running out of money  ?



No.. It doesn’t know what type of plan your SIM card is on. It just knows it can connect to the mobile network.

If PrePay type, you can check the balance with the mobile provider. ONE OPTION is to selecting 'auto top-up' when registering a PrePay SIM card - this way, it never runs out of money.

Battery life


Certain GPS tracker models are battery powered. 

Battery life depends on usage, just like your mobile phone. The more it's used the more battery it uses.

Trackers require to monitor GPS satellites and mobile cell phone towers. If signals to either are blocked, usually by buildings, then the tracker will continue to search for the required signals which will increse the amount of battery power used.
