Anyone can possibly help me? All of a sudden on day last week my phone just started searching for my Sim. Then it has shown it for a short moment here and there. And I have checked the Sim in another phone, emptied cache, restarted numerous times, and also it says im unable to update software. Says a network or server error has occurred please try again later. Please help?!!?

If it didn't work in another phone the physical Sim could be bad. Get a new one from your carrier or do an esim with them if available.
