I believe what it does is executes the order to add a line. I don't know if it is enough to fully complete the process by itself as I believe that you need to turn on the phone with the SIM it shipped with to complete the process. Call Verizon's AOL department if you want to know more as that is all I know.Thanks.
Just so I'm clear:
So the in-store scanning "creates the line".
No, the SIM card is already associated with your account even if you don't turn on the phone. That's why you have to remove it b/f you sell it. But perhaps you could put another 4G LTE phone on the new line and that would bump the SIM in the phone off of your account. Idk.And turning the phone on "activates that SIM to that line"?
Turning on the phone activates the phone on Apple's servers, which I believe starts the clock on the warranty but don't quote me on that.
