I've been using a feature phone up until now, and i'm going to be upgrading to a Droid Bionic pretty soon.

I'm buying the droid used off of eBay, and the seller says there's no sim card included, but the ESN is clean.

I'd like to know weather or not i can simply walk into a Verizon store with my new Droid Bionic,

ask them to deactivate my old Feature phone, and have them activate my Droid with a 3G data plan? (not interested in 4G right now)

Like i said, i'm new to the whole smartphone thing, so please forgive me!
