Before you even consider asking whether you can use your AT&T iPhone on Verizon, be sure you have unlocked the phone first. If you are switching carriers, but you want to keep your current cell phone, you will need to make sure that your phone is unlocked. If your phone is still locked to Verizon, you will have to bring it into the store and get them to unlock it for you. If your phone has been on your Verizon plan for at least two months, then you do not have to worry about getting it unlocked.
Verizon sells unlocked phones, so you do not have to ask. T-Mobile is a little different than other carriers, as you can purchase an unlocked iPhone for their network straight from Apple. If you are planning on upgrading to the iPhone and you want the freedom to switch to any carrier, you are better off getting the Verizon model, as it comes with a factory unlocked version day-one, and it will work on any of the four major carriers in the U.S. with no issues. There are even ways to have your AT&T phone transferred over to Verizon.

When you purchase an iPhone–unless you paid full price for an unlocked model–it is restricted to the networks of the phone company that you originally chose to use it with. Rather, a locked phone is one that is compatible only with a single carrier or cell network, while an unlocked phone is usable with any carrier. The phone that you wish to unlock must be locked/activated with the carrier you are asking for unlocking (i.e., AT&T is not going to unlock the Sprint iPhone, Sprint has to).
The phone you are going to ask for an unlock on has not been marked a lost or stolen device before. Basically, you will have to call Customer Service at (877) 746-0909 to receive the mobile device unlock code for the iPhone purchased through T-Mobile.
