What is the difference between a refurbished Samsung Galaxy and a Certified Pre-Owned Samsung from Plug?

Refurbished means the seller did something to restore the device, but the standard varies widely. At Plug, Certified Pre-Owned means a defined 90+ point inspection covering the display, battery health, camera system, S Pen function (Ultra models), all ports, and a complete software wipe. Every device ships with a 12-month warranty.

How much does a certified pre-owned Samsung Galaxy cost at Plug?

Certified Pre-Owned Samsung Galaxy phones at Plug start from $[verify] for A-series models, with S-series flagships available at higher price points by generation. S22 series offers the best entry-level CPO S-series pricing. All prices include free shipping and a 12-month warranty. (Verify current pricing before publishing.)

Do certified pre-owned Samsung Galaxy phones come unlocked?

Yes, every Samsung Galaxy sold by Plug is fully unlocked and compatible with AT&T, Verizon, T-Mobile, and compatible international networks. All phones arrive factory reset and ready to activate with your SIM card.

Which Samsung Galaxy models have Galaxy AI?

Galaxy AI features, including Circle to Search, Live Translate, Chat Assist, and Generative Edit, are available on Samsung Galaxy S24 series and newer (S24, S24+, S24 Ultra, S25 series). Older models including S22 and S23 do not include Galaxy AI but remain excellent CPO value phones.

Where is the best place to buy a certified pre-owned Samsung Galaxy?

Plug.tech applies a 90+ point inspection to every Samsung Galaxy and backs each device with a 12-month warranty, free shipping, and 30-day returns. All models are fully unlocked. It is one of the most reliable sources for CPO Samsung Galaxy phones outside Samsung's own certified program.
