How To Turn Off And Deregister iMessage When Switching Phones

If you switch from an iPhone to another phone and forget to turn off iMessage, text messages from other iPhone users may never reach you. Apple’s servers continue routing messages through iMessage instead of SMS, which causes missed texts.

Deregistering iMessage removes your phone number from Apple’s messaging system so messages deliver normally. The steps depend on whether you still have access to your iPhone or iPad.

How To Turn Off iMessage If You Still Have Your iPhone Or iPad

If your Apple device is still available, this is the fastest and most reliable way to deregister iMessage. It immediately removes your number from Apple’s servers.

• Insert your active SIM card or enable your eSIM.
• Open Settings.

• Tap Apps and select Messages.

• Turn off iMessage.

• Go back to Settings and open FaceTime.
• Turn off FaceTime.

Once both features are disabled, your number is no longer linked to iMessage.

How To Deregister iMessage Without An iPhone

If you sold, lost, or no longer have your iPhone, Apple provides an official online tool to deregister iMessage remotely.

• Open Apple’s iMessage deregistration page.
• Select your country code.
• Enter your phone number.
• Complete the security check and tap Send Code.
• Enter the verification code sent to your phone.
• Tap Submit to confirm.

Apple confirms once your number is removed. Future messages will arrive as standard SMS.

How To Sign Out Of Your Apple ID To Fully Disable iMessage

If you plan to give away or sell your Apple device, signing out of your Apple ID ensures iMessage and FaceTime are completely disabled.

• Open Settings.
• Tap your Apple ID name.
• Scroll down and select Sign Out.
• Enter your Apple ID password to confirm.

This step prevents any lingering message routing issues.

Troubleshooting Common Problems

If texts still do not arrive after deregistering iMessage, give Apple’s servers several hours to update. Restart your phone and ask a friend with an iPhone to send a new message.

If messages still appear blue on their device, repeat the deregistration process or verify your number is no longer listed under iMessage settings.

Tips

• Always turn off iMessage before removing your SIM card.
• Deregister FaceTime along with iMessage to avoid delivery issues.
• Wait up to 24 hours for Apple’s servers to fully update.
• Test message delivery from both iPhone and Android users.
