What is an "unlocked" iPhone, and can I use it on verizon's network?
This is my first post on the forums, and I wanted to start off by asking a few questions before hopefully transitioning from android-->ios.
I just wanted to know what exactly it means when a phone is unlocked, and if it can be used on verizon's network.
I want to buy a used iPhone 6 plus from somewhere, such as Swappa (as I have had good experiences with it in the past with buying android phones), and have been keeping my eye on verizon devices, but have also been looking at unlocked devices which seem to be more in number, and better in price.
I have read some of the forum posts and things online, but I am still confused as to whether or not an unlocked iPhone 6 plus will work on verizon at all.
I have read in some places that one can move their verizon sim card from their android phone to their new iphone, but my Note 4 has a micro SIM card, while the iphone 6 plus uses a nano sim card (if I recall correctly). I have also read on other websites that I would need to call verizon to have them activate it (or something?) or I would have to go online to Verizon's website to see if the specific iPhone device can work on the network, which would be difficult as I won't have the phone itself until I buy it, and I don't want to buy it if it won't work.
From experience, what is my best option?
TL;DR: can I buy an unlocked iphone 6 plus and use it with my verizon sim card that is in my note 4 (or somehow get a new nano sim card) without a huge amount of hassle
