Haha what do you guys do on your phones that you need that much data for. Unless your streaming Netflix all the time I can't understand all that data. I use a Verizon iPad and my phone all day on the internet for my work. I have a 2gig plan for my iPad and 3 gig plan on my phone. I have never gone over 75% on my phone and have gone over on my iPad like 4 times with way way heavy use.
I stream Pandora most days in my cars too.
