Chosen Solution

Hello, Hoping for a fix here. I dropped my phone for about 10 seconds in some water. It has been repaired (as far as I have been told) as follows:

  1. Alcohol “bath”
  2. New Screen
  3. New Battery
  4. New Antenna Now, the phone appears to be perfectly fine. It connects to WiFi, it charges, camera works, speaker works, etc… But I simply cannot get a cel signal. It says “No Service”. I have rebooted. I have toggled Airplane Mode. I have swapped SIM cards with my husband’s phone. Nothing has worked. Are there any other suggestions as to what I might try to fix this? If you need more information, I would appreciate some direction on where to look/how to diagnose so that I can relate the answers to your questions to you. Thank you so much in advance. I am beside myself because the phone seems perfectly fine, and I would hate to spend the money on an upgrade if I really don’t need one and it’s an easy fix. Thank you again.

@unccgirl in the dial screen type in *#06# to see if it shows the imei, if not it could be a baseband or baseband power problem

Did you contact the service? It seems unlikely to run out of service immediately after an incident, but not impossible.

Have you tried this step from the iphone 6s troubleshooting guide? " Weak or lost wireless connections You have trouble connecting to a wireless network. Dirty antenna grounds If your iPhone has been disassembled before, it’s possible that finger oils were left on the grounding locations for the Wi-Fi or Bluetooth antennas. These oils will cause grounding issues for the antennas, which could lead to a weak signal or no connectivity at all. Be sure to clean all grounding points with an electronics cleaning solution (a little isopropyl alcohol and a lint-free cloth can also work) before reassembling your iPhone to prevent grounding issues."

There will more than likely be some kind of board level issue that would need to be found with test equipment like a multi meter and is more than likely a result of progressive corrosion caused by its recent swimming lesson, Seeing as its got worse over a period of time. When it was treated to the alcohol bath did all the shields on the boards get removed? Were the chips checked under?
