Recovering Your “On My iPhone” Calendars After Switching Apple IDs

Many iPhone users experience challenges when managing multiple Apple IDs, especially when it comes to accessing local data like the “On My iPhone” calendars. If you’ve recently switched Apple IDs and find that your local calendars are missing, you’re not alone. This guide will help you understand the issue and provide steps to recover your calendar data.

Understanding the Issue

When you create a new Apple ID—such as to take advantage of a free trial for Apple Music—and later revert to your original account, some data associated with the previous Apple ID, including locally stored information like “On My iPhone” calendars, may become inaccessible. This occurs because calendars stored locally on your device are linked to the specific Apple ID under which they were created or last used.

Common Reasons for Missing Local Calendars

Switching Apple IDs causes local data to become hidden or disconnected.
Logging out and back into different accounts may prevent the device from syncing certain local data.
The local calendars are not stored in iCloud, making them non-recoverable via iCloud sync when changing accounts.

Steps to Attempt Calendar Recovery

Check Calendar Settings
Open the Calendar app.
Tap “Calendars” at the bottom.
Look for any calendars labeled “On My iPhone.”
Ensure they are checked and visible.
Verify Default Account Settings
Go to Settings > Calendar > Default Calendar.
Confirm that your preferred local calendar (usually “On My iPhone”) is set as default.
Switch Apple ID Temporarily
Sign out of your current Apple ID:
- Settings > [Your Name] > Sign Out.
Sign back into your original Apple ID.
Check if the local calendars reappear.

Note: This step may cause some data to be re-synced or restored if stored locally.

Restore from iPhone Backup
If you have a recent backup made before switching Apple IDs, restoring from that backup may recover your calendars.
Connect your iPhone to a computer with iTunes (or Finder on macOS Catalina and later).
Select your device and choose “Restore Backup.”
Select the relevant backup and restore your device.
