Although I have read some negative reviews, I decided nevertheless for this device. Initial difficulties I had not the device, but with the SIM card, which was to be opened only with code. Finally, I could turn it off with the help of my old mobile phones. And the tracker works excellent. He responded promptly and without snags on the SIM commands. We were on holiday abroad and he gave the same GPS data like my sinfully expensive Navi. I'm very satisfied. We will find our camper repeatedly.
