Well, there would be zero information on that scenario, since Google doesn't know whether the user is trying to port in from a mobile carrier's number provisioned on a mobile phone, or a mobile carrier's number provisioned on a fixed terminal (a AC-powered device into which a RJ-11 jack telephone is attached). That's no different than porting in a number assigned to an iPhone vs. a Android phone vs. a dumb flip phone. The mobile carrier's phone number is being ported, not the particular device on which it is being used.
All Google knows, or cares about, is the carrier that holds the number. As long as it's a mobile carrier's phone number, with working service, located in an area that Google's carrier can support, then the number is portable.
So: fair question, with a simple answer: yes, as long as the number itself is portable, it doesn't matter how it is being used.
