"People always ask us "How do you make money with such low prices? What's the catch?" The answer is simple. Wirefly doesn't make money when we offer you a cell phone for free.
But after you've paid your wireless bills to your carrier, such as Verizon Wireless, Sprint, or T-Mobile, those carriers pay Wirefly for having helped get (or keep) a good customer.
When you take advantage of Wirefly's discounted prices, you simply agree to keep your cell phone account in good standing for the length of your contract. When you do that, Wirefly gets paid.
So there is no catch. You get exactly the same device as the carrier retail store, the carrier gets a good customer, and Wirefly gets paid by the carrier.
No money is made on the phones. Carriers are paid by the contracts. I sold wireless. Might get a spiff on some phones but the money is made on contracts and upgrades
