Samsung’s Galaxy S21 5G is one of our favourite high-end phones, but a lot has changed since it launched back in January 2021. Maybe you want to trade in a Galaxy S21 5G, sell your phone, or downgrade to free up some cash? Why not check us out first.
Mozillion’s marketplace connects people like you with thousands of others, all looking to get a new or pre-owned mobile phone they can rely on. We inspect and verify every used smartphone, performing a secure data wipe, and protecting the buyer with a free 24-month warranty. People pay more for the certified refurbished phones sold through Mozillion, so you get more to spend on your next phone - or anything else you like!
Shouldn’t I trade in my Galaxy S21 5G?
Nope. It’s as simple as that. While a Galaxy S21 5G trade-in is easy, you’ll never get the true value of your phone. More than that, you’ll only get a discount on a new phone - what if you’re downgrading, or you want to free up some cash? You get more money when you sell a Galaxy S21 5G through Mozillion, and you’re free to spend it where you like.
How do I sell my Galaxy S21 5G?
It couldn’t be easier to sell your Samsung Galaxy S21 5G through Mozillion. There’s no need to take photos or write a description, and you won’t need to deal with any buyers or enquiries.
Instead, simply tell us whether you’ve got 128GB or 256GB of storage. Did you play it safe with Phantom Grey or white, or did you make a splash with pink or violet? And is your phone tied to a network, or unlocked and ready to drop in any SIM?
We also need to know about its condition. If it’s never been out of the box, that’s Brand New, but more likely it will be one of the following:
- Pristine - used, but you’d never know it. Truly immaculate
- Excellent - you might spot a minor blemish up close, but nothing at arm’s length
- Good - a phone that’s lived, but swerved any cracks or dents
That’s all we need to know. Now you need to choose whether to Sell Now to the highest current bid, or set an Asking Price and wait for the offers to roll in. When someone matches your price, your phone is sold - simply send it to us within two working days and we’ll take care of everything else. Oh, and did we mention we’ll save you more money when you buy a new phone?
