Hi ​@sunnys 

Thank you for sharing, however I am terribly sorry as the system does not allow us to port internally. You can however transfer from a different network to our network or transfer from our network to a different network. The only way to keep your number with iD mobile is to do an upgrade from your old contract which will convert to a new one keeping your old number.

This is mentioned on our iD Community website and the links are below:
