No matter what others are saying, AVOID Teltonika devices!
We had made a BIG mistake installing almost 30 FM1100 devices on our cars and to some clients.
As stated before, by other users, these devices freeze with no reason and stay like that until you send a reset command over sms.
On top of that is the Support Dept of Teltonika. In fact, there is NO support, because the sales representatives are the only one who you can talk to. For simple questions you must make a ping-pong over couple of days to obtain a plain answer.
And that's not all. If you want support for the devices you bought, Teltonika tells you to pay 200 euro or buy more devices to help you with technical questions. This is a totally BS! Vilius Cepulis is one of those from the sale dept that asked for money to get support.
So, for your peace of mind, AVOID with all costs Teltonika gps units!
