The bands that the Pro 1 uses doesn't mean much if they block you from using their services.

Also, what do you mean by which SIM card? Are you talking size?

I think it goes by phone generations typically. Do a quick search for cards and you'll see what I mean they all have different product codes.
I've never activated an unknown phone before on the network so let's see how this goes.
I think Verizon customers will have to varying degrees a semi similar problem

Your SIM, or Subscriber Identity Module, does have a number associated with it, called a SIM serial number (SSN). This number is also referred to as the integrated circuit card identifier (ICCID). ICCIDs are stored in the SIM cards and are also engraved or printed on the side of the card.

The format of the ICCID is: MMCC IINN NNNN NNNN NN C x
MM = Constant (ISO 7812 Major Industry Identifier)
CC = Country Code
II= Issuer Identifier
N{12} = Account ID ("SIM number")
C = Checksum calculated from the other 19 digits using the Luhn algorithm.
x= An extra 20th digit is returned by the 'AT!ICCID?' command, but it

Both make it very clear (to me) that the ICCID is nothing more than a way for your carrier to identify you and know whether or not you are allowed to attempt to use their network. It is nothing more than an identification number on your SIM, not a separate card for your phone.

As far as interchangeability goes, I imagine each phone needs to be activated to each card, so you can't swap without the card being activated to that phone.

EDIT: Just to be clear, I was only trying to help save you from purchasing a phone you couldn't use on your carrier. I would be very pleased to hear that you can use the Pro 1 without any issues. It has just been my experience that Sprint and Verizon don't play nice with "unknown" phones. Hopefully the Pro 1 having CDMA bands will help with this? I sincerely hope it works out for you.

I am very happy that in general a SIM can be put into any phone and it works. Sprint seems to be a US provider. I am really sorry for you that you have to deal with this. In whole Europe, Brasil, Australia and even China it just works.
