No mobile network since latest update

[kreditt]

Hi folks!

Today i updated my x compact to 34.4.A.2.32 and i dont have mobile network ever since. Phone needs a lot of time to even recognize my SIM. I did not touch my SIM Card so it's in the right place and position. I did reboot the phone several times, even used the Hard reset function, nothing changed. I wrote to the customer service on chat but no one was available. What can I do now?

Try connecting the phone to wifi and downloading the internet setttings in Network & Internet

Thanks for your help, but that did not improved the situation. Anything else?
