My phone is officially dead as well I received a voicemail and it stopped working however I did receive almost a full year out of my phone and if you do the math I actually only paid 25 bucks a month roughly to have that phone with full data access in which I was definitely using over 15 GB a month .  In addition to that I can sell the phone and get some money out of it .  However if anybody else discovers a flaw like this in the future I will definitely try it again so message me if you read this.
