Yes. I've own both phones that I've bought on swappa.

Hi Lucy, Swappa is a user-to-user marketplace where buyers and sellers connect to buy and sell tech. All phones are used, and must be fully functional. Our support team reviews and approves all listings before they can be bought (including ESN checks when appropriate). This is a security feature to help protect buyers and make Swappa the safest place to buy and sell used mobile devices online. If you have any more questions, feel free to reach out to us at help@swappa.com
