So I have an android smartphone with LTE. My dad has a dumbphone, just a basic phone. I'm going to use his upgrade to get an iPhone, and switch it to my account. What do I have to do about the nano sim card? Do I have to go to Verizon to get one for my account or what? Also, since its for my dads line, do I need to activate it on his line first, then can immediately reactivate it on my line?
