I suppose she could mean her online phone account..I have to sign in to see my phone/text records BUT! that doesn't seem to be what she's talking about..Besides, she can't read any of the texts or listen to any of the voice mails so what's the point? And why is she doing this anyway? She has to know this is up to LE! not her..Very strange!
To me its pretty obvious she is talking about voicemail. You dont need the phone, just the number and code.
