   2. In the No longer have your iPhone? section, enter your phone number in the Phone Number field.
   3. Click Send Code.
   4. Apple will send a message to your phone to confirm your de-registration. Enter that code in the Confirmation Code field.
   5. Click Submit.

Note: To optimize device performance, be sure your LG G4 is running the most recent device software. Check for software updates.
