Will Buying "SIM-Free" iPhone from Apple Work on Verizon

I currently have verizon and I'm looking to upgrade my phone. If I buy the phone from this page http://www.apple.com/shop/buy-iphone/iphone5s and choose the "SIM-Free" option (below), will that work for me? or do I have to click the verizon button and put my account info in? Also, I currently have an android phone, that requires a verizon sim card. Can I just put my old simcard into the new iPhone when it arrives? Thanks in advance.

Solution 1:

There are two different iPhone 5s models sold in the US -- the CDMA model for Verizon or Sprint (which also supports GSM connectivity for international use) and the GSM model. The unlocked phone is the GSM model, so it won't support CDMA and won't talk to Verizon's network (except perhaps for data (not voice) on 4G/LTE, where Verizon uses GSM like the rest of the world). So you can buy an unlocked phone and put a Verizon SIM in it, but it will at best only work with Verizon for data, and only in areas where they have 4G coverage.

Just look at the bottom of the page you link to in your question, where it says:

If you buy a SIM-free iPhone, you will need to purchase a GSM-compatible nano-SIM card separately. In the United States, you can purchase such a SIM from AT&T or T-Mobile.
