Resetting network settings on an iPhone clears Wi-Fi passwords, cellular data configurations, VPNs, and Bluetooth pairings to fix connectivity glitches, restoring them to factory defaults. This common troubleshooting step often resolves issues like dropped Wi-Fi or slow cellular data without erasing apps or photos.

Step-by-Step Guide

Follow these detailed steps on iOS 15 or later (including iOS 18 as of 2026), which remain consistent across recent iPhone models from iPhone 11 to 16 series.

  1. Open the Settings app on your Home Screen.
  2. Tap General , then scroll to the bottom.
  3. Select Transfer or Reset iPhone (or Reset on iOS 14 and earlier).
  1. Tap Reset.
  2. Choose Reset Network Settings.
  3. Enter your device passcode or use Face ID/Touch ID to confirm.
  4. Tap Reset Network Settings again; your iPhone will restart automatically.

The process takes under a minute, and your device reboots with fresh network configs.

What Gets Reset

  • Wi-Fi networks and passwords : You'll need to re-enter them.
  • Cellular settings : APN and data plans revert; reconfigure if customized.
  • VPN and APN configurations : Deleted, so note them beforehand.
  • Bluetooth pairings : Devices like headphones must be re-paired.

Personal data, apps, and photos stay intact—this isn't a full factory reset.

Before You Reset

  • Backup passwords : Jot down Wi-Fi credentials or use a password manager.
  • Try simpler fixes first : Toggle Airplane Mode, restart your iPhone/router, or forget specific Wi-Fi networks via Settings > Wi-Fi > Info icon.
  • Update iOS : Ensure you're on the latest version (check Settings > General > Software Update) for optimal network stability.
