I’ve bought a iPhone and I replaced the screen on it as the screen was completely smashed and black but I have no signal, I think it has something to do with the antenna but not sure

Check if the IMEI and modem firmware is being displayed in settings > general > about phone. Also check in the phone dialer with *#06# for IMEI being displayed.
In most cases these are baseband circuit related issues which requires micro-soldering from a reputable phone repair store to fix.

check you've not bought a blacklisted phone!

The lphone is not black listed, I’m going to try a replacement antenna to see if it works, if it doesn’t I’ll have to see about taking the phone to a micro soldering store. Please throw more answers down, thanks!

I think it’s your logic board issue.
Watch this video and you ll understand, wether it’s a board issue or not.

If I leave the phone flat on the table it picks up a network with no bars but if I have mobile data on it shows up that it’s using some data from the setting menu, would this still have anything to do with the baseband circuit?
