Using my previous Verizon SIM card for a prepaid plan

Here is my situation, I bought an unlocked iPhone a year ago through Apple, connected to my existing Verizon account. Then I moved abroad and ported my US number to google voice (effectively disconnecting my Verizon line), and switched to a prepaid local SIM (but I still have the Verizon SIM). I am going back to the US for the holidays and am looking at getting a prepaid SIM for my time there.

2 questions

  1. Can I use my existing Verizon SIM or do I need to order a new one?
  2. If i use my existing Verizon SIM and order a prepaid plan online today, does it activate today or once I put the SIM in my phone?
