Mi 9T Pro / K20 Pro Mobilfunk nicht verfügbar / Problem?

[WalkerLena]

Hi everyone, sometimes my Mi 9T Pro shows "no cellular network available" when I want to call someone. Mobile internet (not WLAN) still works. So I can be called via Whatsapp but not via normal mobile communications. It works in both directions. I cannot call and cannot be called. When I restart my cell phone everything works normally again, but the same problem occurs 2 days later. Unfortunately, I also can't see when someone tries to reach me and therefore miss a lot of calls because I don't notice that the problem is there again. essay writer
Can someone give me a tip how I can fix this?

Hast Du schonmal den SIM-Slot gewechselt oder Testweise eine andere SIM-Karte verwendet?.. Wielange besteht denn das Problem schon...könnte es sich um ein lokales Problem deines Mobilfunk-Providers handelnd? Hast Du dein Gerät Testweise auf Werkseinstellung zurückgesetzt..?
