Hi ​@Sandiwayboy.

Thank you for your post. 

It sounds like what may have happened is that a new additional contract was set up, rather than your existing number being upgraded, that would explain why a new number has been issued instead of keeping your old one.

To confirm exactly what's happened on your account and sort this out, could you please contact us directly via https://www.idmobile.co.uk/live-chat.

Thanks,
