Like Reminders, you can easily restore contacts on your iPhone. You can use the same method that we've discussed in Part 2 (Method 2). Please not that this method will only work if you have the contacts synced on iCloud ID. Follow the below steps: Step 1. Open the Settings option and select the iCloud option. Step 2. Select the Contact option. Once clicked, it'll display a pop-up. Select the Keep on my iPhone option. Step 3. Click on the Merge option to complete the process.
