I have a Dell latitude notebook with an LTE modem, which does not work with Telekom (T-Mobile HU) SIM: “No network” 
When installed latest Dell driver package Telekom mobile network changed to “Firbidden”, and, of course “No network”:…
Firmware version: SWI9X30C_02.24.05.06. Any idea?
Does it work for other SIM card?
you can try newer FW:
Yes, it works with other SIM.
I tried to install the new fw (SWI9X30C_02.38.00.00) , but it didn’t work, Windows shows the same fw version. :-/
what did it show in the command prompt message?
Did you install the latest USB driver?
