We pay up to £576, paid the same day.
The amount you are quoted for your Galaxy S25 Ultra reflects the condition you choose, so cracked screens, a worn battery and other damage are accounted for up front. A free collection, the Haverhill counter and posting the phone in all lead to the same amount. Once the handset is inspected, the confirmed amount is held for 14 days, and payment goes out the same day your identity and address are verified.

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 S25 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 S25 Ultra works
No haggling, no waiting on a callback, and no offer that quietly drops when you arrive.
Get your price
Pick your Galaxy S25 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, by bank transfer, or store credit towards an upgrade or downgrade.
Your price
What your Galaxy S25 Ultra is worth depends on
Storage
Bigger storage means a better price. Tell the finder above which Galaxy S25 Ultra you have and it prices that exact variant.
Check the storage capacity of your Galaxy S25 Ultra before you start. mendmyi accepts the 256GB, 512GB and 1024GB versions, so choose the one that matches the handset 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.
Sell your Galaxy S25 Ultra in whatever condition it is in. A cracked screen, scuffs on the casing or general wear are all part of the condition options, and the amount you are shown is matched to the state you describe.
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.
Collection is free when you sell this phone, and you can also bring it to the Haverhill counter or send it through the post. Whichever route you pick, the amount you receive is the same.
Once mendmyi has inspected your Galaxy S25 Ultra and confirmed the amount, that figure is held for 14 days. You have that full window to complete the sale, so the amount cannot slip away while you take your time.
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 S25 Ultra in front of us.
The Galaxy S25 Ultra has a 5000mAh battery. If that battery has weakened with use, choose the condition wording that reflects battery wear, and that will be taken into account in the amount you are quoted.
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 your Galaxy S25 Ultra once it is signed out of your Google account, which is what clears Factory Reset Protection.
Before sending the phone, remove your Google account and switch off the screen lock. That clears Factory Reset Protection, so your Galaxy S25 Ultra does not arrive tied to your account and the sale moves through without delay.
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 S25 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. If an upgrade is replacing it, here is our guide to moving everything to your new phone.
-
2.Sign out of iCloud or your Google account
Turn off Find My before you hand over the Galaxy S25 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.

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 to sell
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. We also cannot buy a device that is part of an ongoing insurance claim, or that has been reported lost or stolen.
"This device is not under contract or finance, is not part of an insurance claim, and has not been reported lost or stolen - I own it outright."
We record name, address and ID on every purchase
We record the name and address of everyone we buy from, and check them against photo ID and proof of address. HMRC requires it: buying from a private seller, we have to raise the purchase invoice ourselves and it must carry your details. Bring the documents into the shop and show us, or send a photo if the device is reaching us another way.
It protects you as much as us: the purchase can always be traced back to a genuine sale rather than an anonymous one. A photocard driving licence showing your current address covers both documents on its own.
GOV.UK: VAT margin schemes, section 6.2Your 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 S25 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
“Brilliant efficient service, never ever trade your old Iphones in with anyone else!!!”
“Excellent service. They had my daughter’s headphones and unfortunately were not able to fix them so they didn’t charge me even though they had ordered the part and done the work. Honest, friendly service - would highly recommend”
“A first class service for the third time. I’m glad to see the warranty has been extended to 12 months. Excellent ”
“They fixed my phone right away, thank you”
“I’m genuinely impressed with the service I received. My phone suffered water damage and completely stopped displaying anything, so I thought my data was gone for good. Thankfully, the team managed to recover everything — photos, contacts, messages, the lot. They were professional, quick, and kept me updated throughout the process. What felt like a disaster turned into a huge relief thanks to their skill and care. If you’re dealing with a water‑damaged device and worried about your data, I can honestly say you’re in safe hands here. Highly recommended.”
“Great service, everything explained, professional job. Very grateful and would highly recommend. No more back of vape shops for me! ”
“A friendly, proficient and speedy service. Well done. It is good to have you around.”
“Such an easy and convenient purchase. Helpful and informative staff. Kept me informed and flexible with collection. Really pleased with my purchase and so glad not to have to traipse into a city!”
Selling your Galaxy S25 Ultra
My Galaxy S25 Ultra is still signed into my Google account. Does that stop the sale?
Yes, it will stop the sale progressing until the account is removed. Sign out of Google and clear the screen lock before sending, because that releases Factory Reset Protection and lets your Galaxy S25 Ultra be processed.
I prefer to post my Galaxy S25 Ultra rather than have it collected. Will that affect the amount I receive?
No, the amount is identical by post, by free collection, or at the Haverhill counter. Pick whichever route suits you, because none of them changes the figure paid.
Do you need to see my ID before you pay me for a Galaxy S25 Ultra, and do I have to wait long for the money?
Yes, photo ID and proof of address are required before payment, with no exceptions. Once those are confirmed, payment for your Galaxy S25 Ultra goes out the same day, whichever way the device reached us.
If my Galaxy S25 Ultra has a damaged screen, should I have it repaired or sell it as it is?
You can do either, because mendmyi repairs Galaxy S25 Ultra handsets as well as buying them. If you would like to keep using the phone, repair it; if you would rather not keep it, sell it in its damaged state and choose the condition that describes it.
After my Galaxy S25 Ultra has been inspected, how long is the confirmed quote valid?
The confirmed amount for your Galaxy S25 Ultra is held for 14 days after inspection. You get a full fortnight to accept the figure, so the offer will not disappear while you decide.
When I sell my Galaxy S25 Ultra, is the amount shown online a final figure or an opening bid?
It is a final figure, not an opening bid, so the amount you are quoted is the amount mendmyi pays. Provided the Galaxy S25 Ultra arrives in the condition you selected, nothing is negotiated down.
