How to Factory Reset iPhone & Keep ESIM Mobile Info (Best Method)
Factory resetting your iPhone wipes all personal data, settings, and apps, returning it to its original state, which is useful before selling or transferring it. However, you can preserve your eSIM mobile plan information to avoid reconfiguring it or contacting your carrier after the reset.
Below are the steps to factory reset your iPhone (running iOS 18 or later) while keeping your eSIM mobile info, along with tips to ensure the process goes smoothly.
Steps to Factory Reset iPhone and Keep eSIM Mobile Info
Back Up Your Data (Optional):
If you want to keep your data for later restoration, back up your iPhone:
iCloud: Go to Settings - [Your Name] - iCloud - iCloud Backup - Back Up Now. Ensure you’re connected to Wi-Fi.
Computer: Connect your iPhone to a Mac or PC, open Finder (Mac) or iTunes (PC), select your device, and click Back Up Now.
Verify the backup is complete before proceeding.
Confirm eSIM Preservation Option:
On iOS 18 or later, Apple allows you to keep eSIM data during a factory reset. You’ll be prompted to retain it during the reset process (step 5). Ensure your carrier supports eSIM retention (most major carriers like Verizon, AT&T, and T-Mobile do).
Sign Out of iCloud and Other Services:
Sign Out of iCloud:
Go to Settings- [Your Name].
Scroll down and tap Sign Out.
Enter your Apple ID password and tap Turn Off (for Find My iPhone).
Choose whether to keep a copy of data (e.g., contacts) on the iPhone. Select none if preparing to sell, as this data will be erased during the reset.
Tap Sign Out again to confirm.
Sign Out of Other Services:
Sign out of iMessage (Settings - Messages - Send & Receive- [Your Apple ID] - Sign Out).
Sign out of FaceTime (Settings - FaceTime - [Your Apple ID] - Sign Out).
Manually sign out of third-party apps (e.g., banking, social media) to ensure no accounts remain linked.
Turn Off Find My iPhone:
This is typically disabled when signing out of iCloud. To confirm:
Go to Settings - [Your Name] - Find My - Find My iPhone.
Toggle off Find My iPhone and enter your Apple ID password to confirm.
This removes the Activation Lock, ensuring the device is ready for a new owner or your own reuse.
Factory Reset While Keeping eSIM:
Go to Settings - General - Transfer or Reset iPhone.
Tap Erase All Content and Settings.
Enter your passcode and Apple ID password if prompted.
When prompted, select Keep eSIM (or similar, depending on your iOS version).
This option ensures your eSIM plan remains active after the reset.
Authenticate with Face ID, Touch ID, or your passcode if required.
Tap Continue and wait for the reset to complete. The iPhone will restart and display the “Hello” setup screen.
