Dell Precision 7670 & WWAN DW5930e & Europe
I bought a Precision 7670, unfortunately it didn't have a WWAN connection. So I had to buy WWAN antennas for the display cover and a WWAN card. I found a T99W175 DW5930e X55 5G. I installed the drivers, but the physical SIM card doesn't work, not even e-sim. It keeps saying "no service". The PIN for the card is unlocked. However, on the card is written "for canada only". Is it possible that there are other versions of the card for the EU?

Any idea?

Hi
Does this make any more sense than your cryptic post?
Yes, it will work in Europe. The module supports a comprehensive range of global frequency bands required for European 5G and 4G networks, including:
5G NR Bands: 1, 3, 7, 8, 20, 28, 38, 40, 41, 77, and 78.
G LTE Bands: 1, 3, 7, 8, 20, and 28 (among others).
Additionally, because the DW5930e uses e-SIM only, you will need an active e-SIM data plan from a European mobile network

After install a driver, it automatic update firmware of the card. Than I add esim (Czech O2 connect). O2 told me that according to the IMEI (imei*info) the card is identified as a phone and not as a modem and that is not allowed with O2 connect - sim cards are automatically blocked. So I bought a normal esim tariff (6GB + calls and sms) and added this new card to the WWAN esim profile. Still the sim card does not log in to the network - "no service". Active network "no network found"
