SERPUHOV Hello,
For the LBS button to be displayed, the device must start sending LBS parameters in messages.
To determine the position by LBS, the device must transmit at least 4 parameters: mcc, mnc, lac, cell_ID.
Check if your device can send LBS data, enable it in the device configuration. Then the button will be displayed in the panel on the unit card.
If you have any additional questions, write to us by mail(support@gps-trace.com) indicating the login, unit id and type of device, then we can check it additionally.
