Bought from Sprint, online. Not using a VPN at the time. My VPN does not end up in Portland if I was.
I just got off the phone with Apple Care...
Turns out, that setting is actually a link to Sprint / T-Mobile. The text just looks just like a phone setting.
The phone was in fact brand new.
I looked up the owner of the house and she does NOT have a similar name to mine.
I'm nowhere near Portland, Oregon, so I doubt she ever had my number.
In fact, I have had this number for almost 10 years.
The issue resides with Sprint / T-Mobile.
I'm going to call Sprint later on to see if they can make sense of this.
My worries are gone at this point, though.
Here is a crazy thing...
I sort of have a repressed memory of this happening to another phone of mine or reading about this problem on Mac Rumors years ago.
Or, perhaps I read that Apple once had an address entered somewhere unusual that showed up with many phones and it was some sort of default address.
Reminds me of the house on google where all the victims of lost phones go to. Similar situation on google maps where there is an unusual GPS quirk.
Another similar situation is where people used to sell their old phones and the Apple ID messages kept going to the old phones despite being wiped.
My Sprint account is locked down real good and I never got hacked that I know of. Also, Sprint has been rated as the most secure national wireless carrier due to having certain security measures in place on the user account end of their business. That is not to say their phones can't be hacked but their website has been using proper security measures before the other carriers were.
I'm going to investigate this further with Sprint but at least the issue has been narrowed down and is not urgent.
I hope other people chime in...
