Prepaid account & internet access

I have quite a large balance in my account, and was wondering if usage fees would be withdrawn from that? 

If so, how would I go about initiating a data plan?  Thanks!

You can either add a data option (which will be renewed automatically from your current account balance every 30 days) or purchase one-time Data Passes (valid for a day, a week or a month, depending on your needs). This being said, make sure you refill your account before the expiry date or you'll lose your account balance!
