noob question RE: sim card

[aslondon]

I am a little unclear about getting a sim card to work with the B1.  I have an old iphone which I have taken out of service.  Do I need to reactivate it then pull the sim card out and put it in the B1 and keep the cell account active under the iphone label?  Or do I just rry to add a new line of service with no phone attached other than the B1 and ask verizon for a sim card?  I have a Galaxy Note 20 Ultra that I am keeping as my main number.  I'll use the B1 as a back-up phone.  

Thanks in advance.  My B1 should be here monday so it may become clearer at that point.
