So, I still have a "Grandfathered" Phone plan from Alltel, on my Smartphone, with unlimited Data. They recently Nerfed the ability to ADD new plans to such packages as of June 2012, but they left Phones still on these plans alone.
There is a way, and you might need to have some decent connections with people here, to swap your Sim Card from your Phone to a 4g Usb Internet Device and Have unlimited 4g Internet. Big Deal Right? Well, if you are in a fairly Rural Area, you can get Download speeds up to 20 Mbps, and uploads up to 15 Mbps. With the Right Equipment ($800), you can also Boost that signal to max even if you live out in the sticks like me.
I Did this with my old phone, and just purchased a new phone under a crappy verizon plan. Basically Giving me 20x the speed of my Old Unlimited data 3g Card for $20 Less.
