  • Amazing device definitely recommend to anyone looking for a Samsung
Color: Phantom Black Size: 256GB
I was hesitant about purchasing a device especially a latest model like this one, due to people saying Amazon doesn’t give good phones, but it came in excellent condition! I’ve had it for a couple of months now and I am very much happy with my purchase and no issues at all. I love this device and use it practically everyday!! I even was able to put T-Mobile 5G esim and it was incredibly smooth process. 12/10 I don’t regret a single thing :) ... show more

  • Don't buy a phone from this seller.
Color: Phantom Black Size: 256GB
The seller sent me an unlocked phone from Europe. The software operating system is corrupt and phone keeps freezing. Because it's from Europe, no one in the United States can re-download the operating system, so the phone freezes and won't work properly. And, of course, the window for return closed 2 weeks ago, so I'm stuck with a phone that doesn't work properly, and my only means to get it fixed is to send it directly to Samsung with a 4-6 week wait. I'm supposed to go without a phone for 4-6 weeks. I would not buy from this seller. ... show more

  • Perfect condition!!
Color: Phantom Black Size: 256GB
I decided to wait a few days before writing my review...and my phone came from RE-CELL. First off, I ordered this the Friday before Labor Day. Estimated arrival date was the following Friday. They shipped it the VERY NEXT DAY (Saturday). So, I had high hopes of getting it early. I was pleasantly surprised to get it on Tuesday! The condition was amazing. Not a scratch on it! I went into the phone info to confirm it actually was the s21+ with 256GB storage....and it is. I bought black because it was cheapest and I was getting a case anyway. It came with a charging cord, wall plug, and the tool to open the SIM card door. No issues with setting up and it's unlocked so I saw the change right away in my phone plan. Battery lasts all day with lots of use, unlike my old phone. I also appreciate that it was packaged snugly to avoid damage during delivery. Great phone and great job by RE-CELL on the fast delivery! Definitely recommend. ... show more

The Samsung S21+ in Phantom Black has lived up to the hype and then some. As my first dive into Samsung's lineup, I'm thoroughly impressed by the value this phone offers. It boasts a slew of high-tech features without a hefty price tag, striking a perfect balance between cost and performance. The high refresh rate is a game-changer for screen smoothness, making every scroll and swipe a pleasure. Combined with a top-tier camera, capturing moments in stunning clarity has never been easier. It's a solid choice for anyone looking to enjoy the latest in smartphone tech without overspending, proving once again why Samsung stands out in the crowded Android market. ... show more

  • Just as amazing as what you'd expect
Color: Phantom Black Size: 256GB
I love every aspect of this phone. Though biased because I am a samsung lover. This is one of the best products I have bought so far. Still figuring out the phone day by day. But if someone can help me figure out how to add my spotify to my lock screen to where I can change my song without having to unlock it and etc. I'd really appreciate it very much hehe. I am techny savvy as all get out and it is throwing me for a loop on that. So I guess for right now that is my only real complaint and I know it's on my part and not the phone manufacturers part ... show more

  • Reliable Phones
Color: Phantom Black Size: 256GB
This is the 2nd phone I've purchased from this seller over the last 7 years and I'm very pleased. Phone arrived and was ready to work. My last Samsung also served me well for 3-4 years. I had an Apple in between that was from another seller that did not work too well and lasted under 1 yr. I have not had any issues with this seller so not sure type of response you may get. But I'm happy to say that I've had no reason to contact the seller or attempt a return. The product s21 works well and looks brand spanking new. I'm very pleased. ... show more
