Hello, good day.
Please consider that sending data from the device also depends on "Data Acquisition" or "I/O" settings configuration. Check that parameters have been set correctly to enable data packet sending. If the issue still remains, then it would require in-depth analysis.
For that purpose, please contact your sales manager. If you don't have any contacts with our Sale managers, please contact with them on our official website https://teltonika-gps.com/
and click on the "Contact Us" button. When you will click, please fill the form and submit it. Note: as a topic, please choose "Vehicle telematics". Or you can send an e-mail with description of your situation to [email protected]
When contacting Us, please provide: IMEI/Logs/Configuration file/Intenational GSM number/Firmware version/ect, please follow these recommendations: https://wiki.teltonika-gps.com/view/Recommendations_for_filling_a_query_description
