I purchased a Droid Mini from an everyday "Joe" and realized after purchasing this item that it was actually on on active account with Verizon.. "joe" ran up a huge bill and it is do to be paid on September 29th... Someone told me that if I take the sim card out that has his info on it that I could put a new one in it and make it prepaid... Is this so can I just change the sim card that was installed ... reset it back to factoy setting's and get a new sim card myself and still continue to use the phone? Please someone Help!
