An epic screen, 5G, 8K video - is there anything the Samsung Galaxy S21 Plus 5G hasn’t got covered? But alas, even the best phones have their day - maybe you want to move on, or downsize to something cheaper and smaller? Either way, here’s why you should sell a Galaxy S21 Plus 5G through Mozillion.
First up, Mozillion exists to add a much-needed layer of trust to selling and buying mobile phones. We protect sellers with a secure data wipe - and by guaranteeing they won’t lose their phone to a scammer. We look after buyers by subjecting every used phone to our industry-leading inspection and verification. What’s more, there’s the protection of our free 24-month warranty: buyers pay more for a phone they can trust, so you get more when you’re selling one.
Shouldn’t I trade in my Galaxy S21 Plus 5G?
Sure, if you don’t mind missing out on £10s or even £100s compared to its true value. While a Galaxy S21 Plus 5G trade-in is easy, you’ll only get what the networks are offering - and you’ll only get it as a discount on a replacement phone.
Sellers on the Mozillion marketplace get more - just browse our phones for sale to see for yourself. And we’re talking about real money, not a discount - you can spend it on a new phone, or anything else you like.
How do I sell my Galaxy S21 Plus 5G?
Here’s how to sell a Samsung Galaxy S21 Plus 5G in under 100 words. Simply tell us how much storage it has, and which of the five available colours you went for. Is it unlocked, or tied to a UK network?
And what about the condition? Select from:
- Brand New - literally never out of the box
- Pristine - used, but immaculate
- Excellent - looks immaculate at arm’s length
- Good - lived a bit, but no cracks or dents
Finally, choose to Sell Now to the highest bid, or set an Asking Price and wait for someone to match it. When they do, send the phone to us - we’ll look after everything else!
