1. Go to a corporate store.
2. Call customer service and request one.
3. Go through the online switch device option in your MyVerizon account and at some point it will ask you if you have a SIM card. When you indicate that you don't have one, it will give you the option to request one be sent to you.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
