I received my refurbished Galaxy S10e phone very quickly. The phone is in wonderful condition and working perfectly. All communications from Back Market were respectful, fun, friendly and informative. I'm very happy that I chose to buy from them.

I bought the Samsung Galaxy z Flip 4 & it arrived on time & in perfect condition. I was really impressed. The phone is fully refurbished & it looks like it came straight out of the Samsung store. I'm extremely impressed with the quality of the mobile phone and Back Market.

Excellent,I am delighted with it. I used to use a Ulefone armor x6 pro,could it does not come close to the s7. I took a chance and bought a refurbished phone and Samsung is the most popular phone on the market at the moment. Keep up the good work. Regards, and many thanks Ciaran.

Fast delivery which was great. Quality of my refurbished Samsung s21+ was near perfect. Zero scratches or marks on the phone. Have had the phone about a month now and still perfect. The charging cable was not a fast charge cable but not a big deal as had one from previous phone. Would highly recommend backmarket.ie, and I will be shopping here again in future.

Really happy with the phone! It is in perfect conditions, no a single scratch, the phone is like new. The battery also in perfect conditions. I can’t be more happy buying this refurbished phone instead of brand new.

Make your Samsung dreams a reality

Back Market offers unrivalled low prices on refurbished Samsung smartphones, so you’ll find a smartphone you love, whatever your budget.

Buy refurbished Samsung for the lowest price

Back Market has listened to consumers and understands what is important when buying new technology. Reliable products that don’t break down quickly and that are priced fairly are the main factors when making a decision. Each refurbished Samsung smartphone or tablet undergoes scrupulous tests and checks in our laboratories before it is ready to be resold. Giving a second life to these unwanted, but otherwise perfectly good, smartphones is not only good for your wallet, it’s also good for the planet. Reducing electronic waste is important to Back Market, and we know it is important to you too.

As with all our brands on Back Market, Samsung is no exception to the huge cost savings we apply to each refurbished smartphone. There is almost nothing to distinguish between a used device sold on Back Market and a brand new one on the high street. Having undergone tests and any necessary repairs, our experts deem each smartphone in perfect working order, before it is repackaged and sent out to its new owner.

What’s the benefit of buying refurbished Samsung Products?

Buying a refurbished Samsung smartphone from Back Market is almost risk free, unlike buying a second-hand smartphone from an auction site or through an individual, you’ll receive a 12-month minimum guarantee. You’re protected in case of any unlikely future defects, so you can get it repaired or replaced free or charge or choose a full refund.

Get fantastic discounts of up to 70% off retail prices on the latest Samsung technology with Back Market’s range of refurbished Samsung smartphones - you won’t find a better offer! Buy with confidence thanks to the protection of our guarantee for 12-months as standard.
