Swapping phones

[djs4855]

I am getting a ZTE Blade A3 when I open my account and want to know what I need to do when I want to upgrade to a IPhone 7 Plus that someone is giving me? Do I just swap out the sim card?

There are 2 versions of 7 plus. Make sure the iphone 7 plus you are getting supports the visible carrier band.
