iphone 8 plus no service(sim card can’t read) after water damage Hello all how are you? Dropped iphone 8 plus into the water then I cleaned mother board by alcohol everything works fine except no service network carrier i think something wrong with cellular antenna which part i need to replace? maybe charging port? thanks all
There are a few antennas being used (mainly the antenna cables near the charging port are used for cellular 3g/4g) and a few things you should check is if imei is displayed when dialing *#06#, also modem firmware and imei displayed in settings > general > about phone. I would expect some board-level repairs needing to be done after liquid damage. I recommend taking the phone to a reputable repair shop that does board-level / liquid damage repairs for liquid damage evaluation.
