Please insert sim card issue s21 ultra

[IneptxPython]

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.

I get this too and it's so annoying, thinking of changing my phone because of it.

Try replacing the sim card.

Haven't tried yet but annoying if it's the solution

[IneptxPython]

Yeah Samsung definitely need to get on this then

[kingtom]

I know . It might be a sim issue or try a factory reset and see if it resolves the issue

[IneptxPython]

Yeah two bad options

Hi,
Please check ur sim in another device to see if u have the same problem. If u do the sim is faulty and if u don't then the phone is faulty.

my phone is the Samsung a20e and it has dual sims. They are both fairly new, just and sometimes the phone doesn't see either of them.

Ur sim is definitely faulty. You will need to contact ur network provider and have it replaced.
