iTrackLTE vehicle GPS tracker

I ordered the iTrackLTE vehicle GPS tracker on 17 August 2021 and was delivered on 20 August 2021. I took a few days to familiarise myself with the GPS tracker. The most important thing about the tracker is to ensure it's fully charged, a prepaid SIM card is inserted, switch it on and you are all set. However, I've noted that the device does go to sleep mode after five minutes and reactivates within forty seconds when you SMS or call (i guess it's to conserve power). The device works as it's supposed to, you send an SMS or call and it sends you the coordinates of its current position. One drawback, because it uses GPS, signals can be obstructed by tall buildings. Other than that, love the device.
