Apple 4s Using Tracfone BYOP I am looking into buying a used Apple 4s to use as a Tracfone through Tracfone BYOP. I want to be sure that I know my facts before investing money into this venture. Please let me know if I'm missing something or have the wrong info.

Tracfone BYOP Requirements:

Used Apple iPhone 4 or 4s/
Verizon Carrier/
Clean ESN/
UNLOCKED/
Must Have Verizon SIM Card/
Must be CDMA

Question ~~ Does the iPhone HAVE To Have A SIM Card?

ANY Help Will Certainly Be Appreciated! Thank-You!
I have just activated (Nov 20, 2014) an iPhone 4s that had been on the Verizon System.  It had to be unlocked for international use.  It had to be active on the Verizon System to do the unlocking.  The previous owner of the phone kept the sim card so it does NOT have a sim card installed.  It functions 100% as a Tracfone.
