Hi ​@Westie007,

 

Thanks for sharing, please could you try the below steps:

  • Go to Settings
  • Tap Phone
  • Tap My Number
  • Delete the old number
  • Enter the new number
  • Tap Save

 

Then follow these steps to refresh iMessage:

  • Go to Settings
  • Tap Messages
  • Turn iMessage OFF
  • Go to Settings > General
  • Tap Reset
  • Choose Reset Network Settings
  • Once your iPhone restarts, go back to Settings
  • Tap Messages
  • Turn iMessage ON again

Your iPhone should now recognise the new SIM and verify your number.

 

Regards,
