Sell your Galaxy S10 Plus for cash

Storage, carrier and condition decide it. A 1TB unlocked in Good condition is $56. The same phone in Average is $48. A 128GB with a cracked screen is $7. Put your own combination through the quote box at the top of this page for the exact figure.

These are honest numbers for a seven year old phone. We would rather show you the real ones now than quote high and have an argument when the box arrives.

Check the storage first. Every 1TB S10 Plus Samsung made has a ceramic back and a ceramic frame, and the 512GB was sold in ceramic as well. The 128GB is Gorilla Glass 5 on the back, like the rest of the S10 family.

If you are still unsure, weigh it or just feel it. Ceramic is 198 grams against 175 for glass, so it is noticeably heavier for the same size. Ceramic also stays cold longer in your hand and reflects light in a flat sheet, where the glass Prism backs throw a color shift as you tilt them. The ceramic ones were only ever sold in plain white or plain black, so a green or a pink one is glass.

Yes, and it still pays, though we will be straight about how much. A Faulty S10 Plus is $7 at 128GB, $9 at 512GB and $11 at 1TB, against $56 for a Good 1TB with nothing wrong with it.

Any crack and any chip, anywhere on the phone, grades Faulty no matter how well it works. The curved screen edges on this model crack readily because the glass wraps round exactly where the phone lands, and a ceramic back fails the other way: it shrugs off the everyday scratching that leaves glass looking tired, then takes a flake out of one corner. The panel can be spotless and the corner still puts you in the bottom row.

Check with a fingernail rather than your eyes, case off, under a lamp. All four corners, both long edges, the back and the frame. Something that catches is a crack or a chip. Something you can only see is wear, and wear is Fair at worst. Quote it as Faulty from the start and nothing changes when we open the box.

Burn-in grades Faulty, and this screen can get it, because every Galaxy S display is OLED. On a phone that has been switched on for seven years it is worth a real look rather than an assumption. What burns in is whatever never moves: the clock at the top, the status icons beside it, and the navigation bar across the bottom. Put the brightness at maximum, open a plain white image in a dark room, and tilt the phone until the light rakes across it. A faint permanent ghost of any of those shapes is burn-in. The full walkthrough, including Samsung's own on-device test, is on the Galaxy S23 Plus page and works exactly the same here.

Two things that are not burn-in and should not cost you a grade: a single dead or stuck pixel, and the green or blue cast every OLED takes on when you look at it from a sharp angle.

It does. The Samsung rule is broader than the Apple one and it is easier to remember: if something on the phone does not work, the phone is Faulty. There is no half step and there is no short list of parts that count, because everything counts.

A dead headphone jack qualifies, and so does a loudspeaker that buzzes, an earpiece nobody can hear you through, a fingerprint reader that has stopped reading, a wobbling camera, a volume button that needs two presses, or wireless charging that has quietly given up. Pick Faulty, take the Faulty price, and there is nothing to sort out later.

No. There is no battery percentage rule on Samsung phones, so there is no figure to look up and no screen to go hunting for. A 4,100 mAh battery that is seven years old and wants a top up by the afternoon is simply an old battery, and it does not change what we pay you. The only way the battery affects your grade is if it has genuinely stopped working, and that is covered by the same rule as any other broken part.

Look at the front camera cutout. The S10 Plus has a wide pill shaped cutout in the top right corner holding two lenses, because it has a depth sensor next to the selfie camera. The Galaxy S10 has a single round hole. That is a one second check from across a room.

Size backs it up. The Plus is 6.4 inches and 175 grams, the S10 is 6.1 inches and 157 grams, and the Galaxy S10e is 5.8 inches with flat sides to the screen instead of curved ones. The certain answer is Settings, About phone: SM-G975U or SM-G975U1 is this phone.

Not that one, no. With no power we cannot test it and neither of us can clear your data off it, so any price would be a guess. Give it a full hour on a wall charger with a cable and a plug you have seen work on something else before you decide it is dead, because a seven year old phone that has sat in a drawer can take a while to wake. If it really is gone, send it on the free label anyway. We will recycle it at no charge, wiped to Department of Defense standards first, or post it back to you, also free.

Not while money is still owed on it. A phone on a carrier installment plan or a lease is under a financial obligation and we cannot purchase it. Ring your carrier and ask for the payoff figure. On a phone this old the balance has usually long since cleared, and once it has, the same carrier will unlock it for free, which is worth real money on this model.

No. There are three separate locks here and all three have to be clear.

The Google account lock, which Samsung calls Factory Reset Protection, has to be off. Take your Google account and your Samsung account out in Settings before you factory reset. That order matters. Reset first and the lock stays on, the next owner is stuck at the setup screen, and the phone comes back to you unsold.

The Knox counter has to be untripped. If this phone was ever rooted or had unofficial firmware flashed onto it, Knox trips permanently and we cannot buy it at any grade.

The IMEI has to be clean. Reported lost, reported stolen, or blocked by a carrier for unpaid bills all fail. Dial star hash zero six hash and the IMEI appears on screen in a second.

Yes, and by more than most people expect. A Good 1TB pays $56 unlocked, $46 on T-Mobile, $46 on AT&T, $30 on Verizon and $28 on anything else.

The grid on this page is the unlocked column, so change it in the quote box if the phone is still tied to a network. If it is paid off, ask the carrier to unlock it before you sell. They do it free, it usually lands within a day, and here it is worth roughly a third of the whole payout.

No. Prism White, Prism Black, Prism Blue, Prism Green, Flamingo Pink, Ceramic White and Ceramic Black all pay to the cent what every other color pays. The ceramic ones are worth more only because they are the 512GB and 1TB phones, and it is the storage doing that, not the finish.

On a phone this old, usually not, and the shape of the offer matters as much as the number. Promotional deals attach the figure to buying a particular new phone, and it normally arrives as bill credit spread across 24 or 36 months of staying on that plan. Leave the plan early and the rest of the credit stops.

A Buyback is a straight purchase. We buy your Galaxy S10 Plus, the money is yours in cash, and nobody minds what you spend it on. Compare the two numbers honestly, and check whether the credit survives you changing your mind.

Back up anything you want first, then go in this order. Settings, Accounts and backup, Manage accounts, and remove your Google account and your Samsung account. Then Settings, General management, Reset, Factory data reset. Accounts first every time, because that is the step that switches the Google account lock off. There are full instructions with pictures on our erase your device page.

Afterwards take the SIM out and take the microSD card out, and delete any eSIM you set up. Your photos, your messages and your saved passwords are erased and they cannot be recovered. We then wipe the phone again to Department of Defense standards when it reaches us.

Four ways, and you choose at checkout. A gift card, emailed, worth about 3 percent more because the brands add their own bonus on top. PayPal, which is instant and carries PayPal's own 2.99 percent fee. A bank transfer, 2 to 4 days. A check, 3 to 5 days. All four go out the same day your phone clears inspection. On a payout this size the gift card bonus is the one worth a look, because 3 percent of a small number is still money you did not have. Sealed Brand New phones are PayPal only.
