Check Sim Card Tray error

Getting a very intermittent issue with the new phone. 

 

Got the Note 20 and use a Samsung clear case with it. 

 

Every now and then and can be days in between I will lose signal and the message "Check Sim Card Tray" pops up. Normally comes up a couple of times and then is ok. 

 

Have tried the sim in Slot 1 and moved it to Slot 2 and same problem. Have tried another Sim in the phone and Sim is ok. All as Samsung support suggested.

 

Tried another Sim in the phone but still same problem. 

 

Regret beginning to set in.

If you've tried other sim cards that you know work in other phone's then if a factory reset does not help then approach who supplied the phone if not Samsung and either ask for a new phone if your within any cooling off period or if out of the cooling off period go to a Samsung Experience Store or Samsung Service Centre @Divvykev for a diagnostic.

 

 


Daily Driver > Samsung Galaxy s²³ Ultra 512Gb in Phantom Black.

The advice I offer is my own and does not represent Samsung’s position.
I'm here to help. " This is the way. "

Thanks for that. Will try a factory reset now. See what happens. 

 

Cheers

A possible work-around, and certainly not a solution, would be to install an eSim.

Forgot to post a solution. OTA's give the problem. if I flash the whole rom using odin then the problem goes away. Hope this helps someone.

Did you try to flash the rom? I think you can do it through smart switch too but it will wipe your device and needs to be setup again.

Flashing using Odin solved the problem for me.

Didn't the problem recur on your device?

I have the same problem on Note 20. I'm going to try the firmware via Odin at your advice.

I can confirm that divvykev  method worked on my Samsung Note 20.
Firmware via Odin (without deleting data) solves this problem.
The "Check Sim Card Tray" message no longer appears.
_____
Проблема с сообщением "Проверка лотка SIM-карты" и пропаданием сети на Samsung Note 20 решается путем перепрошивки через программу Odin, с сохранением данных на телефоне.
