If you’re using it with Windows then you should probably switch it to RNDIS (3) or MBIM (2).

In MBIM mode same problem.

In RNDIS mode not all device drivers are installed and a blue screen.

Firmware version EC25EUXGAR08A07M1G_01.001.01.001 is latest?

Was APN and PDP Type configured?
I would use any terminal app and run a few standard checks with AT commands, starting from network registration check.
