SELL YOUR GALAXY S25 ULTRA
A Galaxy S25 Ultra is worth between $105 and $655 today, and every figure in between is printed in the table below. Storage sets the ceiling, the carrier lock sets the tier, and the rest comes down to what a year of pockets and desks has done to the glass. The quote takes about a minute.
Before anything else: a Galaxy S25 Ultra sent without its S Pen grades Faulty, whatever else is right about it. The pen sits in a silo in the bottom edge of the phone and it ships in the box, so it counts as part of the handset rather than as an accessory, and it is the one part of an Ultra that gets left in a drawer. Slide it out, slide it back in, and check it is there before you tape the box. If yours is genuinely gone the phone still sells, but grade it Faulty when you quote.
A word on what to call this, because the difference shows up in the order things happen. A carrier trade-in hands you the credit up front, against a handset you walk out of the store with, and your old phone is assessed weeks later in a building you will never see. If that assessment disagrees with you, the correction turns up as an adjustment on a bill a few months later, long past the point where you could have changed your mind. A Buyback runs the other way round. No money has moved when your Galaxy S25 Ultra is opened and checked, so there is nothing to take back. If what we find does not match what you told us, you get the revised number first, and you can accept it or have the phone posted back to you for nothing.
The Galaxy S25 Ultra S Pen has no Bluetooth. Samsung removed it for this generation. So the S Pen cannot fire the camera shutter from across the room, and Air actions do nothing at all. That is normal on a Galaxy S25 Ultra. It is not a fault and it does not change your grade.
The missing Bluetooth is also how you tell a Galaxy S25 Ultra from the phone before it. Pull the S Pen out and press its button. On a Galaxy S24 Ultra the button can fire the camera from a distance. On a Galaxy S25 Ultra nothing happens.
Unlocked handsets pay the most here, at every grade and every storage size, and the table below is the unlocked price. Every carrier option comes in under it, at every size and every grade. Search your settings for Network Lock or SIM lock. If it says Unlocked, choose Unlocked. If not, pick the carrier you actually pay a bill to, because we check the lock when the phone arrives.
We buy used Galaxy S25 Ultras and we buy cracked ones. Sell your Samsung Galaxy S25 Ultra for cash here and the shipping is free in both directions. A Galaxy S25 Ultra that will not power on is one we cannot buy. We recycle it for free and wipe it on the way.
LIVE PRICES
The used resale value of a Galaxy S25 Ultra runs from $105 for a cracked 256GB up to $655 for a sealed 1TB. Most phones land in the middle. A used 512GB in Average condition is $526.
How much you can sell your Galaxy S25 Ultra for depends on storage, wear and whether it is unlocked. Every figure below is pulled live from our own price feed.

HOW IT WORKS
Choose 256GB, 512GB or 1TB, then your carrier, then the grade that matches the wear. To find your carrier, search your settings for Network Lock or SIM lock. If it says Unlocked, choose Unlocked. If not, choose the carrier you pay your bill to. The Buyback price you accept is locked for 14 days.
We email you a prepaid USPS label. Put the S Pen back in its slot first. A Galaxy S25 Ultra without its S Pen grades Faulty. Remove your Google account, remove your Samsung account, then erase the phone. Take your SIM card out and leave the empty tray in the phone. Keep the charger, the cable and the case. None of them are priced into the quote.
Your Galaxy S25 Ultra clears inspection within 48 hours of arriving. If the phone matches what you told us, payment leaves the same day. Pick a gift card, PayPal, a bank transfer or a check. Every phone gets a DoD-grade wipe, whether we buy it or recycle it.

GALAXY S25 ULTRA BUYBACK QUESTIONS
An unlocked 512GB Galaxy S25 Ultra in Good condition is worth $560. That same 512GB in Fair condition is worth $336. A 256GB Galaxy S25 Ultra with a cracked screen is worth $105. Storage, wear and the carrier lock are the three things that set the price. Use the quote tool at the top of this page for your exact phone.
Pull the S Pen out and press its button. On a Galaxy S24 Ultra that button can fire the camera shutter from a distance. On a Galaxy S25 Ultra that button does nothing. Samsung took Bluetooth out of the S Pen for this generation. The screen is the other clue, at 6.9 inches on the Galaxy S25 Ultra. The certain answer is the model number in Settings, About phone. A Galaxy S25 Ultra reads SM-S938U or SM-S938U1. If yours turns out to be the older phone, our sell your Galaxy S24 Ultra page has its own prices.
Open Settings, tap About phone, and read Model number. SM-S938U is the US carrier version of the Galaxy S25 Ultra. SM-S938U1 is the US unlocked version, sold by Samsung and by retailers. Both are a Galaxy S25 Ultra and both are quoted on this page. We buy the two US models. A model number that does not start with SM-S938 is not a Galaxy S25 Ultra at all.
A Galaxy S25 Ultra with no S Pen grades Faulty. We still buy it at the Faulty price. The S Pen ships inside the phone and it counts as part of the phone, not as an accessory. Missing it drops a 256GB to $105 and a 1TB to $122. A genuine Samsung replacement S Pen costs far less than that drop, so buying one before you sell is usually the better move. If you are sending the phone without a pen, choose Faulty at the quote step.
No. Samsung states the Galaxy S25 Ultra S Pen does not support Bluetooth Low Energy. That means no pairing, no charging and no remote features such as Air actions. The pen still writes, still opens Air command, and still takes a screen off memo. None of that is a fault and none of it changes your grade. Do not quote a healthy Galaxy S25 Ultra as Faulty over a feature this model never had.
Yes. Any crack or chip moves the Galaxy S25 Ultra into Faulty. That covers the screen, the back glass and the camera lens covers, with no exceptions. Faulty is a price, not a refusal. A cracked 256GB pays $105, a cracked 512GB pays $112 and a cracked 1TB pays $122. An engraved Galaxy S25 Ultra is Faulty as well. Choose Faulty when you quote and nothing changes when the phone reaches us.
Burn-in grades the Galaxy S25 Ultra as Faulty. The screen is AMOLED, and an AMOLED panel can hold a faint ghost of anything that sat in one place for months. Test it in a dim room. Open a plain white image, fill the screen with it, and look for a shadow of the clock, the keyboard or the navigation buttons. Any shadow you can see is burn-in. A replaced or aftermarket screen is also Faulty, so tell us if the display has been changed.
There is no battery rule on a Galaxy S25 Ultra. We do not set a percentage on Samsung phones, there is no 80 percent line to clear, and there is no battery health screen we want you to go looking for. If you have sold an iPhone before, that is where the idea comes from, and it does not carry across to this phone.
What decides the grade is whether the phone works. Any functionality issue at all makes a Galaxy S25 Ultra Faulty, and the battery only counts once it has actually failed. That means the phone cuts out while the charge indicator still shows plenty left, or it will not stay on unless the cable is in, or it will not charge at all. A battery that no longer lasts as long as it did when the phone was new is ordinary wear, and it costs you nothing.
A Galaxy S25 Ultra with a fingerprint scanner or face unlock that has stopped working grades Faulty. A biometric sensor that has stopped working is a Faulty trigger on every phone we buy. The fingerprint scanner on a Galaxy S25 Ultra sits under the screen, so a screen repair can kill it without leaving a mark. Unlock the phone with your fingerprint once before you choose a grade. If it will not read your finger, choose Faulty.
Yes. An unlocked Galaxy S25 Ultra pays the most at every grade and every storage size on this model. An unlocked 1TB in Good condition pays $610. The same phone locked to AT&T pays $459. To find out which one you have, search your settings for Network Lock or SIM lock. If it says Unlocked, choose Unlocked. If not, choose the carrier you pay your bill to. If you pick a carrier and we find the phone unlocked while processing it, we raise your offer automatically.
No. A Galaxy S25 Ultra with no power cannot be tested, and your data cannot be cleared off it, so we do not put a price on one. We will recycle it for free instead. Send it on a free label and we destroy the data to DoD standards. Ask for the phone back rather than recycled and the return is free too.
A Galaxy S25 Ultra with money still owed on it is not one we can buy. A phone sitting on a carrier payment plan or a lease counts as being under a financial obligation, and we do not purchase devices under financial obligations. Finish the payments, own the Galaxy S25 Ultra outright, then quote it like any other phone.
No, not until the locks come off. Three separate things have to be right before we can buy a Galaxy S25 Ultra.
Google FRP has to be cleared. Remove your Google account from the phone first, then factory reset it. Reset it in the wrong order and the next owner is stopped dead at the setup screen.
Samsung's own reactivation lock has to be off. Turn off Find My Mobile in your settings and remove your Samsung account as well.
The IMEI has to be clean. A phone reported lost or stolen, blocked by a carrier, or carrying an unpaid balance fails that check and we have to turn it down.
We also cannot buy a liquid damaged Galaxy S25 Ultra, or one too damaged to test properly. There is a step by step walkthrough on our erase your device page, and we run a DoD-grade wipe on arrival as well.
A Galaxy S25 Ultra with a tripped Knox counter is one we cannot buy at any price. Knox trips the first time a Galaxy S25 Ultra is rooted or flashed with custom software, and it can never be reset. Secure Folder and Samsung Wallet stop working once it trips, so it is easy to spot from the phone itself. Please do not ship a Knox tripped Galaxy S25 Ultra. We would only have to send it back to you.
You choose your payment method when you accept the quote. A Brand New sealed Galaxy S25 Ultra is paid by PayPal only. Every other grade can take all four. Choosing the Gift Card option adds a 3% bonus on top of your Galaxy S25 Ultra payout, on average. Choosing PayPal pays you instantly and costs you a 2.99% PayPal fee. Choosing a bank transfer pays you in 2 to 4 days. Choosing a posted check pays you in 3 to 5 days. Payment goes out the same day your Galaxy S25 Ultra clears inspection. Brand New and Flawless pay exactly the same on this model. A Galaxy S25 Ultra you opened and looked after loses nothing, and it can still be paid all four ways.
Pick your storage, your carrier and your grade. It takes about a minute, and we hold the price for 14 days.
