You can’t.

At least, not right now.  I’d love to be able to tell you that you can save $100 by switching to Verizon, but verizon arguably has the best network and now a pretty good selection of phones right now so I guess they really don’t see the need to offer you a discount to switch. This may change in the future though because there’s some tough competition in the smartphone space right now from T-mobile, Sprint and a few others too like the fantastic deal on the Moto X that’s upcoming from Republic Wireless.

T-Mobile offers a few deals on Samsung phones right now like the Samsung Galaxy S4 for just $99.99 up front, with the rest payable in payments over 2 years. Even though this is $100 cheaper than Verizon, this isn’t really incentive to switch to Verizon. In fact, it may make you switch the other way away from Verizon instead

Sprint is the only carrier currently offering a $100 discount on any phone when you switch your number over to Sprint. This means you can get some pretty cool phones for $100 like the Samsung S4, HTC One, and Moto X and iPhone 5s too. But you have to come from another carrier to get this deal.
