Yes, what many retailers call "refurbished," we call Certified Pre-Owned. The difference is our standard: every Plug CPO iPhone goes through a 90+ point inspection covering the display, battery, camera, speakers, buttons, and software before it ships. You get the same device quality with the added peace of mind of a 12-month warranty, something most refurbished sellers don't offer.

Every Certified Pre-Owned iPhone from Plug includes a 12-month warranty covering hardware defects. If anything goes wrong within that year, we'll repair or replace your device. We also offer extended coverage for additional peace of mind.

Yes, every iPhone we sell is fully unlocked and compatible with all major US carriers including AT&T, Verizon, T-Mobile, and smaller carriers. Just insert your SIM (or eSIM) and you're ready to go. No carrier lock-in, no hidden activation fees.

Plug CPO iPhones are priced up to 60% below the cost of the same model new. Exact savings depend on the model and condition grade you choose. All prices include a 12-month warranty and free shipping, so the price you see is the price you pay.

Plug.tech is a leading destination for Certified Pre-Owned iPhones. Unlike general marketplaces, every device we sell has been individually inspected, graded, and certified, not simply listed and shipped. You get a 12-month warranty, free shipping, and a 30-day return window on every order.

It depends entirely on where you buy it. Buying from Plug means your iPhone has been certified by trained technicians, tested across 90+ hardware and software checkpoints, and backed by a 12-month warranty. That's a very different experience from buying an untested used iPhone from an individual seller. Plug CPO iPhones arrive looking and performing like new.
