I bought iPhone X with air machine I put it in because I had a USIM that I used before, but it says 'No service' and it doesn't work at all.
Why can't I use the USIM that I used well before?

pu1. I think it's because of the history of opening, but you can go to the direct management of the carrier you're using

pu2. In the case of an air machine, there are cases where you need to have a history of opening to use the existing USIM. You can take the opening history to the dealership
