For some reason every other day I get an error message saying check that your sim is inserted properly and then my sim stops working, when trying to use data or anything sim related it says please insert a sim for network services as if it doesn't recognise its inserted.
When ejecting it and putting it back in it fixes it completely until the next day or some times later the same day.
No water damage and no major drops at all.
I think it's a software bug since it works fine until something triggers it like some sort of auto sim refresh and bugs out after.
