How to Remove a Mobile Number from a Previous iPhone

Remove a mobile number still associated with a previous iPhone so it can be used elsewhere.

When you port a mobile number to SIPcity that has been used on an iPhone, messages from iPhone users may continue to arrive via iMessage on your device instead of as standard SMS to your SIPcity app. This occurs because your number is still registered with that iPhone’s Apple ID.

Remove a number from an Apple ID

  1. Go to the Apple iMessage deregistration page.
  2. Enter your phone number.
  3. Apple will send a confirmation code to your number via text message, you will receive this in your MySIPcity app.
  4. Enter the code on the website to complete deregistration.

Your number will then be removed from the iMessage service and you will receive SMS messages through the MySIPcity app.
