This information is completely wrong. You can't rely on databases like FoneFinder with number porting anymore, since you can move your number to another carrier. You can see the call rate on your bill, but if you don't want to call, many carriers have a text message option on their site that will fail, confirming their number ISN'T with that carrier if it doesn't work.

Observation works: if they have an iPhone in the US, they probably have AT&T. And don't forget about social engineering!

Doesn't work when someone ports their number to another provider later in their life
