  • Great Phone just like new

10/10 this product is absolutely amazing! No scratches or scuffs on the device. The battery life is still good display is still great and most importantly IT'S NOT A FAKE MODEL!!!!!. I'm someone who likes the s21+ model better then the current models design wise and I'm so glad I was able to get another s21+ since I traded my original one in years ago. Now the box did not come with the correct Samsung charger brick but that's no problem since I have the original still. All in all 10/10 on my book ... show more

This is the second device I bought. As it is renewed, it is heavily discounted. Everything is much better than you can expect from a 220-dollar phone: incredible camera (I had an s21 ultra before, and the pictures are almost the same if zoom is not that important to you), 120 hz display is buttery smooth, excellent speed, and most importantly fantastic battery life. It is probably the best value phone in the market. You will have a premium experience with an entry-level price tag. If used or renewed does not bother you much, go for it, you will not regret it. And as Amazon allows a 90-day return policy, you can rest assured. Extra note: avoid buying from GreenTech Refurbished, the first one I bought from them, it was cosmetically very poor with super deep scratches on the screen even sometimes visible while the screen is on MANY THANKS, Seller Cellmigo, they are amazing, sent me almost like a new product even though I ordered good condition. So buy from them if available ... show more

Maybe I just got a bad one, but I spent half a day running around to Verizon stores tryin to get the phone to work. The phone was beautiful out of the box no scratches no dents and even had a protector on the screen. Was very pleased with that aspect. Then I began transferring all of my data. Hooked up to wifi then the phone shut off. So I turned it on and began an update. Once my phone was restarted the wifi disconnected, and I noticed I had no cell service.. so then I tried to make a call and send a text and I had 0 service. Took my phone to Verizon and spent 3 hours there. They tried everything they could and they were unable to get it to take the SIM card. They tried eSIM and rebooting the phone etc. They informed me that the phone was LOCKED or had a bad SIM processor. The service rep. Did say sometimes they are blacklisted phones. So all-in-all maybe i got a bad one and the rest are good??? But not very happy at all and wasted a bunch of time and $ driving around for no reason at all 🤔. Couldn't get the phone to hook up to verizon ... show more

  • Perfect condition at a great price
Color: Phantom Violet Service provider: Not Specified Memory Storage Capacity: 128 GB Product grade: Renewed
I dropped and broke my s22 ultra and was needing a phone asap cause I was about to travel. I looked around town at local sellers but they all wanted outrageous prices, and you never really know what you're gonna yet. Especially where I live. I decided to check Amazon renewed phones just for my trip and I'm glad I did. This phone came in faster than I could get my s22 ultra replaced, and was in perfect condition when it arrived. Not a single scratch on it. The battery life was still good, and didn't drain quickly. It was also factory unlocked like it said, so I popped my sim in (xfinity mobile) and it worked perfectly. It even had the xfinity loading screen now at the beginning. I guess I got the luck of the draw compared to some of the comments on here. I have zero complaints. I just got my new s22 ultra back today, but I haven't transfered anything or swapped it back. I'm thinking I'm just gonna roll with this one for now, and keep my ultra for backup. ... show more

Color: Phantom Black Service provider: Unlocked Memory Storage Capacity: 128 GB Product grade: Renewed
Got this secondary phone as a backup alongside being a business phone. Holds a charge beautifully, and lasts me multiple days when the brightness is low. Even on high brightness it lasts a whole day. Camera works fine, just like my iPhones camera WAY better, since all the photos just feel either overexposed and vibrant or kinda blurry. BUT It does take good pictures only reason the phone is getting 3 stars is cause it is in full functionality not cause of quality. Finger print scanner, face id, all that is fine and thankfully the phone safely locks. But the condition of which the phone came is…paying anything above 150 is highway robbery, unusable without a case due to how bad of condition it is in, photos i took can’t do it justice, sides had really deep gashes, screen was scratched like someone ran wire brushes over it, back camera look like it has seen a grinder. I have the phone and if works, but part of me honestly thinks i should of returned it and got that OnePlus open. ... show more
