Verizon. I was told if you have that $100 3g to 4g promo and/or loyalty discount, buying from radio shack will not get you these promotions by a CSA
Also, from a CSR:
Kaylen: The reason the phones are so cheap through third party vendors like Best Buy, Wirefly, or Let's Talk is because these vendors have their own contract on top of Verizon's contract. With these third party vendors, if you purchase a phone you can not change your plan within the first 6 months or you would incur a termination charge up to $250. Also if you decide to end your contract early, you would have to pay that third party vendor's termination fee and Verizon termination fee amount as well. Does that help clarify the price difference in the phones?
There's your catch
