Best Used Samsung Galaxy S25 Ultra Deals Today

You'll get one of the lowest-priced Galaxy S25 Ultras on the list, fully unlocked so you can use it with any carrier. The price is hard to beat for a flagship like this, and you're also supported by a generous 60-day return window—much more flexible than most alternatives. The seller is top-rated and has stellar feedback, which adds another layer of peace of mind. What makes this listing more approachable is its affordability coupled with the seller's great track record. The main tradeoff? The condition is listed as "fair," so expect moderate wear—it's not going to look brand new, but if you're mostly after value and function, it's a smart compromise. Also, you won't get accessories or the original box, and no charger is included. If you prioritize pristine condition or bundled extras, you might find refurbished options like #3 more appealing (though you'll pay over $80 more for that jump in condition). But for best bang for your buck and low risk, this is a standout pick.

This is a fantastic value if you're tied to AT&T and want a phone that looks and feels almost new. You're getting the larger 512GB storage, so you have double the space compared to many other picks, for a lower price than most. The phone is refurbished to an "Excellent" standard, so expect minimal signs of use. The seller offers a full one-year warranty, which is reassuring, and strong feedback plus top-rated status make this a safe choice. The key downside: it's locked to AT&T, so you can't use it on other networks. You also don't get the original box or accessories. If you need an unlocked device for travel or switching carriers, a similar option like #1 gives you more flexibility, though with lower storage and slightly more cosmetic wear. But if you're an AT&T user, you'll struggle to find a better blend of condition, storage, and price than this one.

Here, you're looking at a device that's refurbished to "Excellent" condition, so the phone should look and perform almost like new, with very light cosmetic scratches at most. It's unlocked too, making it a versatile choice if you ever want to switch carriers or travel. The seller's a top-rated, high-feedback pro, and you get 30 days to change your mind—plus free shipping, which is a nice little bonus. Downsides? You're paying a higher price than the top picks, and you only get the standard 256GB storage (as opposed to the 512GB found in several similarly priced options). There's a third-party charger included, but no box or original accessories. If pristine looks and unlocked flexibility are paramount for you, and you're okay spending a bit more, this is solid. If maximizing value for money is your sole goal, you might prefer #1 for its far lower price or #2 for more storage with AT&T (if you're on that network).

This option is all about low price and excellent seller reliability. The phone is used but fully functional, with only light cosmetic wear—so it'll look quite good for a pre-owned device. The seller is top-rated, with a long track record of happy buyers, and there's a 30-day return window to make sure it's right for you. Where does it fall short? It's AT&T-locked, so you can't use it with other carriers, and it doesn't include a charger, manual, or any accessories—you're truly just getting the phone and battery. Compared to #1, the price is only a bit lower but you give up carrier flexibility. If AT&T is your carrier and you don't need extras, this is a thrifty pick, but if you want an unlocked phone or more storage, it might be worth spending a little more or looking at other options on this list.

This listing gives you a used S25 Ultra that's unlocked for all US carriers and comes with a hefty 512GB of storage, making it a strong choice if you need extra space for apps, photos, and videos. The device has gone through extra steps for sanitation and testing, and the seller offers a full one-year warranty along with a 30-day return window and stellar feedback. That's solid peace of mind. That said, you're paying a noticeable premium compared to other options; you're up around $120 more than the cheapest unlocked S25 Ultras. Also, the listing mentions moderate cosmetic wear, so it won't be pristine—though for many, that's a fair exchange for the extra storage. If you want a super-reliable, unlocked phone with a top warranty and lots of room, this is a safe, if pricier, bet. If you're all about saving cash, options like #1 and #2 can get you similar power for less.

If you're looking for maximum value and don't mind being locked to AT&T, this is one of the lowest-priced Galaxy S25 Ultras in excellent refurbished condition. For the price, you get a phone that should look and feel almost new, and the purchase is backed by a full-year warranty—a big plus for peace of mind. The seller is highly rated, and you get 30 days to return the device if it's not a fit, plus same-day shipping if you buy early enough. Tradeoff: you’re limited to AT&T’s network. This means you lose out on flexibility if you want to switch carriers or travel internationally. You don’t get accessories or the original box, either. Among all options, this is the way to go if you’re after a solid phone, long warranty, and low price—and AT&T is your carrier of choice. For unlocked freedom, you’ll need to spend more or look at listings like #1 or #3.

If storage is your priority, this S25 Ultra gives you a huge 512GB—plenty for heavy app or media use. It's also fully unlocked, which means you can swap carriers when you want, and the seller has an excellent reputation with a 30-day return window. You’ll also get a third-party charger included, which is a useful extra. The main drawback is that the device is graded “Good – Refurbished,” so it’ll show more signs of use and wear than the higher-ranked ‘Excellent’ options. Plus, it’s more expensive than some ‘Excellent’ or pristine-used picks like #2 or #1. You’re basically paying extra for the storage and unlocked status. If you want a phone that looks almost new (and don’t need max storage), you might find better value elsewhere—but if you want an unlocked Ultra with tons of storage and can tolerate a few scuffs, this is a solid, if pricier, pick.

What stands out here is the 17 months of manufacturer warranty still remaining—unusual for a used device. The seller's near-perfect feedback adds another level of trust, and being unlocked, this S25 Ultra offers the flexibility to change carriers. Light cosmetic wear means it'll still look pretty fresh, and you get some aftermarket accessories, including a box, USB cable, and S Pen. A few tradeoffs: there are extra restrictions on returns if you open or repair the phone without approval, and it's not compatible with certain CDMA and MVNO carriers—so double-check your carrier before purchasing. No original warranty paperwork, and there could be additional shipping fees for some APO orders. The price is on the higher side compared to the best-value options, but if warranty coverage is your main concern and your carrier is compatible, it's a safe, low-risk buy.

This is the most pristine refurbished S25 Ultra on the list, and it's unlocked, so you get complete carrier freedom. You'll benefit from a standout 60-day return window (twice as long as most others), a full 1-year Allstate warranty, and top-tier seller ratings—so you get both security and peace of mind. If having a device that feels and looks virtually brand new matters to you, this is the premium way to go. The tradeoff: you’re paying quite a bit more than some other options here—about $120 more than the best-value used or refurbished models. There aren’t any accessories or original box, and storage is the standard 256GB, not the 512GB you’d get on some slightly cheaper locked models like #2. If the look, feel, and warranty are top priorities, this is a bulletproof, risk-free option for a little extra cash. Otherwise, for pure bang-for-the-buck, you can save significantly with a less pristine choice.

If you want the S25 Ultra with massive 512GB storage, unlocked for any carrier, and in excellent shape, this listing ticks those boxes. The seller is well-established and highly rated, and you get free shipping and a 30-day return window. There’s also a generic UL-certified cable included, which is a thoughtful touch for basic charging needs. However, this is one of the most expensive options here and, despite the high price, doesn’t throw in the original box or other accessories. The warranty is only valid if you keep it in the U.S., and the device will show light wear (not brand-new). If top condition and tons of storage are your must-haves and you’re comfortable paying extra, this is a reliable, low-risk pick. But if you’re watching your budget, options like #1 or #2 get you close in performance for far less, though with slightly less storage or more wear.
