I randomly keep getting this error on my 10 month old S21

Screenshot 2021-10-20 at 12.14.53.png

The SIM is inserted correctly, facing upwards. 

I ordered a replacement SIM from Giffgaff and added this into the phone but I am still getting the same message pop up. 

 

Has anyone else experienced this issue ?

Hi
Give the sim card a clean
And delete the cache
To see if fixes the issue

Also try Turning off your phone
Wait about 30s and Power it back on and see if your phone reads the sim card

Samsung has to repair this. My phone was still covered by the warranty.

Hi anyone get any further with this one ?

 

Got my S21 back end of January and now I'm getting this Sim card tray error nearly all the time last 2-3 days.

Have noticed if I don't lock the screen and continually leave display on it doesn't happen. Lock the screen and leave for 20 seconds are so and there's 75% chance when I go to unlock I'll get this error screen meaning anyone trying to call me during the time its locked would go to voicemail. Not good.

 

Has to be a phone issue.

Wasn't expecting that with esim. That was going to be my next thing to do switch to an esim. Won't bother now. Thanks for the heads up
