Wifi, bluetooth, and cellular not working after drop
I recently dropped my iPhone 13 Pro Max, and as a result, it no longer connects to wifi, bluetooth, or cellular data. It also cannot send or receive texts or calls. I'm certain this is a hardware issue because it resulted from a drop, and I have tried all of the software troubleshooting methods available to no avail.
I want to know what kind of internal damage this could be. I haven't taken the phone apart because I want to know what my best option is, and it's possible that paying Apple an arm and a leg to replace it might be the better option. However, if it's easy/cheap enough to repair, I would be interested in doing that. My best guess is that the modem is damaged or disconnected, which I believe is an integral part of the motherboard. Is it possible to fix something like that? Is it possible a different component is damaged or disconnected that affects connectivity?
