Can Droid Charge be used as prepaid phone?

[aj27801]

Hey everyone, new to the site and i have a few ques.Ok i have a Charge that either doesnt have a sim card or had the sim card removed. I wanted to know if i take it to Verizon can i use it with a prepaid plan? Someone told me that it can be done but by a cust service rep or by being taken to the Verizon store.Has anybody tried or done this? Would i have to buy a new sim card or will Verizon send me one? Thanks for any and all help
