Hello,
i’ve found a workaround for the people with the modem firmware problem:
Choose 4G instead 5G!
In the device go to: Network→Mobile→Connection
Choose the correct SIM-Card (the one you use for the internet)
Edit the “Prefered network typ” to 4G/3G auto
Save & Apply
See the attached Screenshots how to do. I know its only 4G instead of 5G, but ist a huge difference between having a little bit slower internet or no internet. Hope that will help you and hope it will help the support for solving this problem.
