iPhone X won't activate

Hey!

I am new here.

Anyway, I bought an iPhone X quite so cheaply because the previous owner said it didn't start.

I've managed to get the phone on.

Everything seemed to work except the screen is broken so I used 3Utools to see the screen in real time.

The phone does not seem to be able to find my sim card, as it just searches all the time.

And when I try to connect to iTunes I get error code "This iPhone could not be activated because the activation information could not be obtained from the device".

See the picture below, I am stuck on the screen smat you look in the right corner and you see that the phone is only searching for signal (even if I take out my sim card).
