When it comes to plans, Boost Mobile keeps things simple. The contract-free carrier offers unlimited voice, text, and data on all three of its plans: You can choose to pay per day or per month and a separate BlackBerry plan adds on a $10 monthly surcharge. Coverage is mostly restricted to the coasts and some of the Midwest, but you’ll be able to choose phones like the BlackBerry Curve 8330 or the Samsung Seek.
Smart Phone Data: Unlimited, but depends on plan length – $2/day; $50/month; $60/month on BlackBerry
Top Phone: BlackBerry Curve 8330 ($149)
