Perhaps you recall the abrupt closure of online phone dealer Wirefly a few months ago. Its parent company Simplexity LLC filed for bankruptcy, and is currently being chopped up and sold as part of debt reorganization. The Wirefly name and website have emerged from this under new ownership with a focus on comparing devices and plans to help you find the best deal.
The new Wirefly doesn't stock or sell phones directly. Instead, it has a variety of phone comparison tools with filters to get the right device and plan on the big four US carriers, as well as pre-paid services like Boost and Net10. When you click the buy button, you're routed to the carrier site to place an order. The new Wirefly is probably a more stable business as it doesn't sell you the phone directly – it's a service to help you make the decision.
If you've still got a beef with Wirefly regarding an order or insurance plan purchased before the bankruptcy, you'll have to file a claim against Simlpexity in its bankruptcy proceedings. Good luck with that.
