Sell my Samsung Galaxy S20 Ultra 5G

The best trade-in price for your Samsung Galaxy S20 Ultra 5G!

If you're looking to sell your Samsung Galaxy S20 Ultra 5G, you're in the right place. So place your order, send your smartphone and start earning money today!

Our Buy Back Store

Since 1999, The Big Phone Store has provided its customers with a knowledgeable, helpful and efficient service and we're always looking to buy back your mobile phone for a fair price.

Below, you'll find out how easy it is to use our Buy Back Store, as well as how much your smartphone is worth. We'll even explain whether you'll be able to sell your water damaged Samsung Galaxy S20 Ultra 5G!

Why sell my Samsung Galaxy S20 Ultra 5G?

Because it's a great handset in high demand. With an extraordinary 108 Megapixel Quad Camera, Fast Charging 45W Battery and Ultrasonic Fingerprint Sensor, you certainly won't be short of offers from buy back stores for it.

But at The Big Phone Store, we're never beaten on price. And because we always pay in cash (as a bank transfer), spend any money you make whenever, wherever and however you like!

And don't forget, if you sell your old Samsung Galaxy S20 Ultra 5G - you'll be giving an unwanted handset a new lease of life. It's estimated that up to half of us have at least five devices rattling around in boxes, cupboards and drawers. So sell your smartphone and give it a new home today!

Buy Back Valuations

We've made things super easy at The Big Phone Store and only use three factors to determine the price of any handset - 'network', 'storage' and 'condition'.


When it comes to 'network', we recommend you first check whether your Samsung Galaxy S20 Ultra 5G is 'locked' or 'unlocked' from its network provider (EE, BT, Sky Mobile, etc.). As a general rule, 'unlocked' devices have a higher cash value, so it's definitely something you should look into if you want to sell.

Just contact your provider or visit their website - they'll have all the information and instructions you need! And remember... Samsung cannot unlock your Galaxy S20 Ultra 5G - only network providers are able to do this.


We accept the Samsung Galaxy S20 Ultra 5G 128GB, 256GB and 512GB. Higher internal 'storage' usually means higher trade-in value!


With 'condition', we've split our criteria into just four categories: New, Good, Poor and Broken.

You'll find all the details you need above and there's further information in our full Terms and Conditions. But here's a couple of tips to ensure better 'condition' with this or any future sale:

  • Always clean your smartphone before sending it, paying particular attention to the port and button areas.

  • Use a screen protector, case and / or cover. They're the best, cheapest, most effective insurance you'll ever buy for your Samsung Galaxy S20 Ultra 5G - your phone is far more likely to be in better condition if you use these items.

Cases, covers and / or screen protectors

We often get asked whether there's a higher cash value for a Samsung Galaxy S20 Ultra 5G sent to us with a case, cover and / or screen protector. Unfortunately, the answer is 'No'. If you send these items with your device, we'll dispose of them in the most environmentally friendly way possible.

How do I sell my Samsung Galaxy S20 Ultra 5G?

At The Big Phone Store, we've made it both simple and straightforward to sell your device. Here's how our buy back service works:

  1. Place your order. Fill in the valuation calculator above and get an instant quotation. Once you accept our unbeatable price, choose a designated bank account for the cash transfer and provide us with only your essential personal details.

  2. Send your smartphone. Usually within 24 hours of an order being placed, we'll send our Welcome Pack. It contains everything you need to send your Samsung Galaxy S20 Ultra 5G to us - including a Freepost Bag and packing instructions.

  3. We receive your order. As soon as your package arrives, we'll send you an email. We then inspect your device and see whether the 'network', 'storage' and 'condition' are as you indicated.

  4. You get paid! Once everything's confirmed, we process your payment immediately!

We aim to pay out just a few days after you've placed your order - a guarantee that's always dependent on postal delivery service times and how quickly you send your device!

Factory Reset

We highly recommend you complete a Factory Reset of your Samsung Galaxy S20 Ultra 5G. This basically returns your device to its original condition and wipes any personal data. Here's our handy guide:

Before proceeding, make sure you have at least 50% battery - if not, connect your Samsung Galaxy S20 Ultra 5G to a power source. A Factory Reset also cannot be undone and you'll permanently lose any data. Always ensure personal data you want to keep is either backed up or transferred to another device.

  1. Turn off your phone.

  2. Press and hold the 'Volume Up' and 'Bixby (Power)' buttons. Only release them when the Android logo appears on the screen (this could take 10-15 seconds).

  3. Using the 'Volume' buttons to navigate the Recovery Menu and the 'Bixby (Power)' to select, find and choose 'Wipe Data / Factory Reset'. When prompted, select 'Yes' - the deletion process can take several minutes.

  4. After this, select 'Reboot System Now' to complete the process!

Can I sell my damaged Samsung Galaxy S20 Ultra 5G?

You can sell your broken Samsung Galaxy S20 Ultra 5G. But note that not every broken / damaged handset can be traded-in for cash. We suggest you first look at our criteria for 'broken' devices (see above). As long as your Samsung Galaxy S20 Ultra 5G meets these conditions (many do), we guarantee you won't find a better price for it anywhere else!

Damaged screens

We often get asked about damaged screens and whether you should fix them before selling your device. While the answer ultimately varies from phone to phone, we always recommend you carefully weigh-up your choices.

You could be looking at a repair bill of up to £269 to fix the screen of your Samsung Galaxy S20 Ultra 5G. With this in mind, consider whether you might actually be better off selling your device as 'broken'.

You can always use our handy valuation calculator to help work out the differences between 'good', 'poor' and 'broken' devices.

Our Recycling Revolution!

If your Samsung Galaxy S20 Ultra 5G is broken or damaged beyond repair, you can still recycle it with us for free! Each year, 250 million handsets are upgraded worldwide, leading to an alarming number of unwanted devices being sent to landfill.

At The Big Phone Store, we're proud of our knowledge and expertise in the mobile phone recycling sector and promise to dispose of all parts and devices in the most environmentally friendly way possible - following guidelines set out by the Waste Electrical and Electronic Equipment (WEEE) Directive, the Environmental Protection Act (1990) and Hazardous Waste Regulations (2005).
