Iphone 12 Pro Max Dropped, no wifi, cellular, or bluetooth.

I recently dropped my iphone down some stairs, the screen is cracked from the top left to bottom right and the top left of the frame is slightly loose, back glass broken as well, which i would still use the device if only the Cellular, WI-FI, and Bluetooth were working! When i click the Wi-Fi settings the slider is greyed out and doesn't move, when i click on the Bluetooth settings it is just a constant loading circle, and when i click on cellular it says Error an update is required to use cellular data on this phone. Excuse me? All of this was working fine before i dropped it, but how am i supposed to update the phone when it CANT CONNECT TO THE INTERNET AT ALL?
