This thing happened to me about a year & half back. Note 20 ultra was not recognizing the sim card in slot 1. I immediately issued a new sim and problem was resolved. Try inserting some other Sims if they are working.

I already tried this but nothing happens

What is MM sim 1 not allowed notification?

This issue happens when your SIM card is unable to connect to your carrier’s network. If you mess with your network’s settings, you are more likely to run into this problem than if you link a phone number that is not connected to your service provider.

notification sent by the supplier to the recipient of when items have arrived or are on their way to them. “Materials management” is the term used for this (MM).

Check if your both IEMI are approved.

I have tried changing sims but doest work
Or i think should be pta issues

[HasanAskari]

Yes I guess so, do you have e-sim option.
Further, try inserting some new sim only in slot 1 and leave the sim 2 empty, if it doesn't work، it's pta issue.

Users experiencing a 'SIM 1 Not Allowed' error on their Samsung phone should first ensure that their SIM card is installed properly. The location of the SIM card slot will vary depending on the model of smartphone, but the tray can be identified by the small hole used to eject the tray. Using a SIM-eject tool or an unraveled paperclip, users can easily eject the SIM tray and verify the SIM card is installed correctly. The issue can also be caused by an incompatible SIM card, as there are different size standards for different phones
