You're not getting LTE. And you sure as hell are not getting unlimited data either. Once again if at&t and Verizon were to go belly up as many here hope Straight Talk would no longer exist since it would not have a network to work on. I'm not sure which part of that you are not getting.
i am getting unlimited data. last month i used 5.2GB. i am on track to use 4GB this month. i have never gotten a text ot warning either. the LTE icon on my SGS3 pops up about 3 times per month. i suspect itis a mistake, but 3G does not support 35mbps speeds. you should do more research before you make an ass of yourself.
