I'm happy the phone condition is as described and everything seems to work well. I didn't expect it to be an American model and heard it can affect 5G connection it seems good so far though so hopefully doesn't pose any issues

Good value for money. Love that the phones are repurposed. They are great phones. I had to buy a better charger but that was no problem. The phone shop were amazed at the bargain I got for my Samsung. Keep up the good work Back Market!

Hello. Firstly, I'm 65 years old which means I'm from the pre-mobile phone generation. I decided to buy this phone to replace my Nokia 2.3 ( which was not functioning properly.) This new phone improves on it in every way. The screen resolution is much better, the display is easier to see in sunlight etc. etc. I opted for the premium version and the phone looks just like a brand new one. I'm very happy with my purchase and would recommend this phone. Thank you.

Item was as per advertised. I didn't realise it was an ex AT&T phone so it has there apps on it that cannot be uninstalled. Regardless, the phone works, is in good condition, and is unlocked for use in Australia

I bought a Excellent condition Samsung S21+. When it arrived the screen had a few prominent scratches on the screen plus alot of other minor scratches only to be told i had been sent a fair condition phone. Yes i could of sent it back but you didnt have what i wanted in stock. I was offered a $40 refund which i took but considering the phone i bought was $380 and Fair was only $308 maybe the refund should of been a little bit more and i did ask.The process to contact was smooth and easy. The person was very helpful. Just be careful with what is being sent

I bought 2 of these, one for myself and one for my wife. I grabbed one randomly and had little trouble setting it up apart from some difficulty changing the temp from F to C. Someone else set up my wife's phone, and later she complained of all the unknown contacts on it. I had to do the factory reset you should have done.
