Product Questions
No, the tracker is fully powered by it's battery.
The battery of the tracker is single use. So once the battery runs out, it's not possible to recharge it.
Unfortunately you can't switch off the tracker. If you know you are not going to use it for several months you can change the tracking profile. For example to the 7 day profile so it sends a location only once every 7 days. This way you will save the battery.
The battery can't be recharged or replaced. So when the tracker is empty, you will have to buy a new one.
The GPS tracker is using the 2G netwerk.
