Interesting. I didn't mention it in my original post, but the TracFone carrier in my and my family's area is in fact AT&T. I'm intrigued by the possibilities this offers.
I received a call from this # was put on hold to speak with a rep. she asked if I wanted to lower my interest rate I tried to tell her I wanted to opt out of their system but she hung up on me. tried calling back but all I get is a busy signal.
