Chosen Solution
My daughter had water spilt on her phone. I opened it up and dried any droplets I could see and wiped with some iso alcohol. I left it open with some silicone sachets in a warm area for about 5 days. The phone switched on when charged but is showing no service so I cleaned the antenna area and tried again. Still no service but when I manually searched for network operators, 3 of them appeared. Does this mean the antenna is working and there is a problem with possibly the logic board or would they show up anyway?
Honestly you’ll have to test a new Lightning dock and find out. You won’t be able to know until you rule out the antennae on the Lightning dock to be the issue Parts iPhone SE (1st Gen) Lightning Connector and Headphone Jack Labor iPhone SE Lightning Connector Replacement
