Doesn't matter. Just make sure you have a Verizon device that you can add to the line. Go to Swappa and get an iPhone 5 or above, or an equivalent Android with LTE. That way you get a SIM that you can put in the device of your choosing.
I have an iPhone 5 with LTE under Verizon's database. Does the person ship me the sim thats selling me the plan? Or do I have to sign up as a verizon customer and then they send me the sim? And does this happen before or after I get the AOL?
