How to Unregister/Deregister iMessage

You might need to deregister iMessage if you have a non-Apple phone and can’t get SMS or text messages someone sends you from an iPhone.

This can happen if you used iMessage on your iPhone and then transferred your SIM card or phone number to a non-Apple phone (such as Android, Windows, or BlackBerry).

If you recently switched from using an iPhone and didn’t turn off iMessage, your number is still sending iMessages, not SMS or text.

 You have two options:

If you still have your iPhone go with these four steps

Step 1. Put your SIM card to your iPhone

Step 2. Go to Setting

Step 3. Tap Messages

 

 

Step 4. Turn iMessage off

 

 

 

If you don’t have any longer your iPhone go with these three steps

Step 1. Go to web page selfsolve.apple.com/deregister-imessage

Step 2. Enter your phone number and click on Send Code

Step 3. Enter confirmation code

 

Now your phone number is deregistered from Apple iMessage service.
