Thank for your question

This is probably an acknowledge issue in your server. If the server acknowledge is not good, then the device will send the same data until acknowledge is done properly.

From the log files of your device is it possible to clarify records information.

Nevertheless, we recommend not to put your device information here but contacting us. You can reach out to us via VIP Helpdesk or contact your Sales Manager. If you don't have any contacts with our Sales managers, please contact them on our official website and click on the "Contact Us" button. When you will click, please fill out the form and submit it.

Note: as a topic, please choose "Vehicle Telematics" or you can send an e-mail with the description of your situation to

Kind regards

I am also experiencing the same problem. Did you solve your problem?
I created a SQL table to store GPS data with composite PK (IMEI, timestamp). When a device sends the timestamp twice, DB rejects one of them, This is annoying me.
