Sell Your Galaxy S23 Ultra
We pay up to £237, paid the same day.
We'll pay you
Calculating your price
Answer the questions above for a firm price
Tell us the storage and condition to sell this phone.
Confirm the checks to sell this phone
Paid the same day
Cash or bank transfer as soon as your device is checked, not store credit.
Price held 14 days
Once we send your offer it will not drop, so you have time to decide.
We repair, so faulty still pays
Cracked screen or worn battery is a job on our bench, not a write-off.
Not the Galaxy S23 Ultra storage or condition you were looking for?
We buy a lot more than we list here. Older iPhones, Samsung and Pixel handsets, iPads, Apple Watches, MacBooks and games consoles all get a real offer, and a cracked or faulty device is still worth something to us because we repair them in house. Tell us what you have and we will come back with a firm price.
No obligation, and nothing to pay. We will not give you a number we cannot honour, so if we need to see it first we will say so.
Three steps
How selling your Galaxy S23 Ultra works
No haggling, no waiting on a callback, and no offer that quietly drops when you arrive.
Get your price
Pick your Galaxy S23 Ultra storage and condition above and the price we pay appears straight away, no waiting for a callback.
Get it to us, three ways
Walk into the shop, book a free collection from your door within 5 miles, or post it free from anywhere in mainland UK.
Paid the same day
Accept the offer and you are paid there and then, cash or bank transfer, never store credit.
Your price
What your Galaxy S23 Ultra is worth depends on
Your Galaxy S23 Ultra's condition is what sets the figure we pay, and we buy it even with a cracked screen or worn battery. The quote you see is the amount you get, with no deductions on arrival. Free collection, the Haverhill counter or posting it in all pay the same.
Storage
Bigger storage means a better price. Tell the finder above which Galaxy S23 Ultra you have and it prices that exact variant.
The Galaxy S23 Ultra we buy includes the 128GB, 256GB, 512GB and 1024GB storage versions. Confirm which capacity yours is before requesting a quote, so the figure you are shown matches the exact storage you are sending.
Screen condition
A cracked screen does not drop you to a faulty price. You keep the condition the phone is otherwise in and we simply take off what the glass costs us to replace, because we replace them ourselves.
Before your Galaxy S23 Ultra is sent, sign out of your Google account and clear the screen lock, PIN, password and any biometrics. A phone still linked to a Google account carries Factory Reset Protection, which would hold up our checks, so clearing these first avoids that delay.
Body and connector
Dents, scuffs and cracks to the casing are graded as part of the overall condition. A cracked back or a bent frame lowers the offer but rarely rules a device out.
You can sell your Galaxy S23 Ultra by booking a free collection, leaving it at our Haverhill shop counter or posting it in. The figure is the same on all three routes, so the way the phone reaches us never affects what you are paid.
Battery health
We check battery condition ourselves on the bench rather than asking you to self-report a figure online, since there is no single on-device reading we can rely on for every brand. A genuinely worn cell comes off at what a real replacement costs us, worked out once we have the Galaxy S23 Ultra in front of us.
The condition of your Galaxy S23 Ultra is what sets the figure we pay. A cracked screen or a worn battery is covered by the condition tier you select when you request a quote, and that same figure is what you receive, with no extra deductions once we have the phone.
Whether it powers on
A device that boots and passes our checks is worth more than one that does not, but a dead handset is still worth telling us about rather than binning.
iCloud or Google account lock
We can only buy a Galaxy S23 Ultra that is signed out of iCloud or your Google account, with Find My switched off.
Original parts matter to the price: an aftermarket screen, battery or camera fitted by someone else changes what we can pay. If you are not sure what is in your Galaxy S23 Ultra, our guide on how to check a refurbished phone walks through what to look for.
Five minutes
Before you sell: five minutes that protect you
Do these before you hand the device over and the sale goes through without a hitch.
-
1.Back up what you want to keep
Photos, contacts and anything else you would not want to lose.
-
2.Sign out of iCloud or your Google account
Turn off Find My before you hand over the Galaxy S23 Ultra. A device still signed in cannot be bought from you.
-
3.Take out the SIM and any memory card
These are yours to keep and are not part of the sale.
-
4.Note down the IMEI
Dial *#06# or check Settings to find it, in case you want a record for your own files.
Want the full walkthrough? Read our guide on how to wipe your phone before selling.
No surprises
Ownership, ID and your data
Three things worth knowing before you sell anything to anyone, not just to us.
The device has to be yours outright
We cannot buy a device that is still under contract or on finance, because until it is paid off you are not yet its legal owner.
"This device is not under contract or finance - I own it outright."
We record ID on every purchase
Like any legitimate device buyer, we record photo ID and proof of address that match, to keep every purchase traceable to a genuine sale.
It is standard practice for any second-hand device buyer, and it protects you as much as us: the purchase can always be traced back to a genuine sale rather than an anonymous one.
Your data is wiped at our shop
Once your device is checked in, it is fully wiped and factory reset at our shop before it goes anywhere else. Nothing of yours is left behind on it.
Locked in
Your price is held for 14 days
Once we send you an offer for your Galaxy S23 Ultra, it is held for 14 days. That gives you time to compare us against the online recyclers before deciding, without the price moving under you.
What Our Customers Say
Rated 5★ across multiple platforms
“Great convenient service, sorted me out with a screen protector quickly when I popped in”
“Popped in to see if worth fixing my mobile. Was very helpful in weighing up if it was worth it or not. As it wasn’t, I just enquired if he had a phone I was looking for. Turned out although they wouldn’t normally of had one, as new out. He did as someone else wanted to change to a larger version. So with in a few hours I had a new phone, which saved me £200 and stopped me wasting any further money on my old phone. Very helpful and informative. Switched cable for one suitable for my set up and put a screen cover on for me at no charge. Wouldn’t hesitate to use again.”

Selling your Galaxy S23 Ultra
Will I get the same amount for my Galaxy S23 Ultra whether I post it, book a collection or drop it at your Haverhill shop counter?
Yes. A free collection, a drop at our Haverhill shop counter and posting the phone in all pay exactly the same figure for your Galaxy S23 Ultra, so nothing about the route changes what you are paid.
Is photo ID really required before you will pay me for my Galaxy S23 Ultra?
Yes. Photo ID and proof of address are obligatory for every sale, with no exceptions, and once both are verified we pay for your Galaxy S23 Ultra the same day, whichever way the phone reached us.
Is the figure I am quoted for my Galaxy S23 Ultra an opening offer that gets negotiated down when the phone arrives?
No. What you are quoted is the amount you are paid, not a starting point, so it will not be reduced when the device arrives. The figure matches the condition tier you selected when requesting the quote.
My Galaxy S23 Ultra has a cracked screen and a battery that no longer holds a full charge. Is that too much damage for you to buy it?
No. Both a cracked screen and a worn battery are covered by the condition tier you select, so we still buy your Galaxy S23 Ultra in that state. The figure for that tier is fixed, with nothing extra taken off when the phone arrives.
Do I need to sign out of my Google account and remove the screen lock on my Galaxy S23 Ultra before selling it to mendmyi?
Yes. Before the Galaxy S23 Ultra is sent to us, sign out of your Google account and remove every screen lock, PIN, password or biometric. Leaving them active keeps the Factory Reset Protection in place, which ties the phone to you and slows our checks.
