Alltel 8703e

I am going to buy an 8703e on eBay to use as my source of communication over the summer, as I will be home from college and my family does not have high speed internet. I currently have the Alltel National Freedom 900 plan with my girlfriend. We get 900 min between the 2 of us, 10 MyCircle numbers, and we each added on a pack for messaging. Is there any way I can add a Connect Pack to give me unlimited data? To my understanding I do not have to get a smartphone plan since I am not buying the phone from Alltel. Any help would be appreciated. I'm looking to not break the bank here, I just want something to use the internet on for the summer.

You do not have to be on a Smart Choice rate plan but you will require the Blackberry feature code on your line which is $45/month.

So that is $45 on top of what we are already paying for our plan??

Anyone??????
