GPS does not work on EG25-G

Hi,

I have a device:

The device has a built-in LTE EG25-G module (installed drivers: Quectel_LTE&5G_Windows_USB_Driver_V2.1). Unfortunately, I do not know what antenna is mounted inside, because I cannot find such information on the manufacturer’s website.

I have the same problem as above… GPS location doesn’t work when I use LTE connection.

When I unscrewed the housing from the LTE module, it turns out that the antenna is only connected to WAN port.

Can the reason for the lack of GPS communication be the lack of an appropriate antenna built into the tablet, and so it needs additional connections between the antenna and the module to GNSS port, or maybe could it be the drivers fault?

Thanks in advance!
