It is true direction to find hardware solution. One guy made this operation and has a success to solve sim-problem: He made the connection between capacitor 933 and capacitor on the sim-slot (marked on the picture). Then, he took the soldering station and he was soldering every pin of NFC-chip...

Hi guys, thank you for advice, it is a good knowledge. But it is not works for me. I tried everything: - I bought sim+SD slot on Aliexpress and change it twice. Not working. - I put to connector apeace of foam with different thikness. Not working. - I disconnect and connet again every connector...
