iPhone SE water damage no service
So my iphone was submerged in a lake for about 2 minutes after my boat flipped. After leaving it in rice for approximately 4 days, I powered it on and found that most functions seem to work. I still have some slight water mark at the top of the screen, but more importantly I get no service on the cell network. If I connect to wifi everything seems to work and I can make calls and get texts via wifi.
Does it sound plausible that the data antenna is fried and I can just replace that component? I can't seem to find an SE logic board anywhere on the internet, so I'm not looking forward to that being my problem.
