I have already talked to total wireless and they can not tell me unless i give them the IEM number thing which I do not have as I am not going to go buy the phone just to see if I can put it on my plan!
It will work as long as the variant you're buying supports band 13 LTE. This means any American version EXCEPT AT&T. Also if it's not from Verizon it will need to be unlocked.
Welcome to Android Central! Since Total Wireless uses Verizon's CDMA network, the V20 you're looking at would also have to support CDMA to make voice calls.
