Sto avendo lo stesso problema, a quanto pare lo slot si danneggia facilmente e non riesco nemmeno ad aprirlo per vedere se posso cambiarlo o ripararlo.
Ma non voglio dato che l'ho acquistato il 12/04/2021 e perderei la garanzia.
Anche se ancora non è chiaro in italia tramite il supporto tecnico capire come fare per mandarlo in assistenza o chiedere la sostituzione...uno scarica barile continuo come sempre.
per quanto riguarda te perchè non chiedi il reso ad amazon?

Hi, @AntonioBATTA since you just bought the MR600 v2, It is not likely a hardware issue.
Could you please test the modem with a different SIM card to check whether it is a compatibility issue?
Hi, @Reigns For your case, Since it was working fine for the last 8 months, It is suggested to check with the local shop retailer to ask for the warranty.
Thank you very much.

Hi, is the hardware version of Archer MR200 V3?
Did you also test the modem with a different SIM card?
If still no good luck, I am afraid there might be something wrong with the hardware of MR200 and it is suggested to contact the local shop retailer to ask for warranty.
Thank you very much.

@TP-Link Watch closely , repeat closely, the SIM card as the metal clamp that "secures it" closes and see if the act of closing pushes the SIM Card out of alignment.
If it does refer to my earlier post.

Thank you for pointing it out 
and it seemed the FAQ did not emphasize this key point.
I will add it to the recommended solution.
