How do I update my iPhone 14 Plus to iOS 27 or 26.6.2 and resolve cell service interference?

I have done everything in the book, but my phone won’t update to IOS 27 or 26.6.2. It won’t show details or update. It’s an iPhone 14 Plus, and now my cell service is being blocked

Did you try to use your Wi-Fi network to update your iPhone?

Make sure that no VPN or Firewall blocks the contact to Apple servers.

  1. Back up your device using iCloud or your computer.
  2. Plug your device into power and connect to the internet with Wi-Fi.
  3. Open Settings.
  4. Tap General.
  5. Tap Software Update. The currently installed version of iOS is shown, and whether an update is available.
  6. If an update is available, tap Download and Install, then follow the onscreen instructions.
