Frequently asked questions

A 'Renewed' Samsung Galaxy S21 5G is a pre-owned device that has been refurbished and inspected to work and look like new. It should come with limited or no wear, and its performance is tested to meet factory standards. Renewed products typically come with a warranty, but this can vary by seller.

The US Version of the Samsung Galaxy S21 5G is designed to be compatible with US carriers and may not support all network bands used by international carriers. It's important to check with your carrier for compatibility before using it internationally.

An 'Unlocked' Samsung Galaxy S21 5G means that it isn't tied to any specific carrier and can be used with any GSM or CDMA network that supports its wireless bands. This provides flexibility to switch carriers or use local SIM cards while traveling abroad.

The 256GB storage option provides ample space for apps, photos, videos, and other content, which can help maintain the device's performance by preventing storage-related slowdowns. However, it has no direct impact on the processing speed or graphics performance of the phone.

Great value for the money (bought second hand). It is May 2025 and it is still chugging along with no issues (other than I could not get the rugged Rokform magnetic case to work with it).

    • Chinese phone
Color: Phantom Violet Size: 128GB
This phone cannot be the US version. It was delivered completely reset, and the primary language was Chinese. Then, OS did not have Google on the phone as a basic installed app, Google, Gmail, Google Play Store, or YouTube; nothing was installed on the phone. I attempted for 5 hrs to simply "install the Google Play Store" on the phone, but all attempts failed on this phone as if it does not allow it. The basic website was a Chinese website in Chinese, I do not believe this was the AT&T US version. Phone was turned on and off multiple times, do not see the AT&T logo or screen on the phone. It was a scam, wasted my time. ... show more

    • Good value for the Money
Color: Phantom Gray Size: 256GB
OK, so I must admit this was my third phone through amazon renewed, the first 2 were questionable when it came to excellent condition. Trust me, they had various issues too numerous to explain. This 3rd phone though is excellent so far. Condition, I would say is practically new. Case and Screen were blemish free, not even signs of fingerprints. The phone is Verizon branded, but does not impact phone service or use. It is unlocked and work with my Tracfone sim through T-Mobile. Testing battery life, but it seems close to normal after a few years of use. Used it all day and I still had 25% battery remaining with really heavy use. Data transfer went flawlessly with no hick ups, very easy and straight forward. Even the sim was immediately recognized without having to call the carrier. Everything seems to be in good working order. The person who owned this phone 1st really took care of it, you can tell. Other than the branding issue on start up and a notification telling me my sim is not a Verizon sim, everything seems to be in good working order. This is an upgrade for me coming from am Galaxy A20s. The upgrade was immediately noticed. And 256gb memory is just enough for me. I carry books, music and movies in my phone and this has handled everything I have thrown at it without issue. The camera is great and takes amazing photos compared to my last phone. Buying through Amazon renewed is a crap shoot really, it depends on the last user(s) and what may have happened to the phone, I can imagine the phone's people are turning in. I'm sure most have issue from over use and drops, to phone malfunctions in general. And from studying the vendors who sell the phones you really have no idea what they might do with them once they are rehabbed, Water damage, electronic issues, even screen replacements. All the phone are going through private phone companies who refurb them and send them back out. Like I said, 3rd times the charm and I lucked up on what I think is an excellent buy. Would I do again, sure, but make sure to check out the phone thoroughly during your 90-day return window. I will continue to test out and report back if any issues popped up. But so far so good. Check the vendor rating and issues reported in reviews. Typically, they spell out possible issues with phones or vendors selling them. I have always believed in recycling items, especially electronics. So do your part and make sure they don't end up in landfill somewhere. I have liked Samsung products for years and this still holds true with this phone. I don't need the latest and greatest, but I know I have a few years still before a newer model takes it's place. Furthermore, I usually hold on to a phone for 2–3 yrs, depends on the phone. Oh yeah, 5G is the hits. Very smooth and fast, no delays when surfing the web, everything just flows like a hardwired home system. 120 mhz is smooth and haven't noticed any hang-ups. Yes, I would buy again through Amazon renewed. But I'm sure you could find the same product locally at your local phone store. I'm happy with purchase and would recommend with caveats. Check your phone carefully, run it through is paces and test everything, camera, sound, display and any function you think is important and even those you might not think is important. test all settings and make sure all your setting take effect. This phone is loaded with options and it took about 3 hrs to transfer and update this phone once I started things up. Gaming is great, and the display is amazing. No glitches during game play. It's almost to fast that I can't keep up visually. So two thumbs up on buy. Finally moving like most with an upgraded phone. ... show more

    • Huge upgrade from my previous phone
Color: Phantom Gray Size: 256GB
I used to have a Galaxy S8 active until I sadly drowned it on accident, I set out to find a goof quality phone that wouldn't break the bank, and this was spot on. It has a great camera quality, and even has the ability to take .5 photos which I was always jealous of other people for being able to do, it's sleek with all the cameras to one side which gives plenty of space to hold or grab the phone at. I haven't noticed it running too hot unless it's an abnormally hot day, or running a very processor heavy app or program. The phone came in great condition, with only some very minor cosmetic damages on the back of the phone, but all functuons worked great, and none of the screens or cameras were cracked. All visible damage is covered by any case I've used. The battery life is pretty good, of course you can stretch it or run it faster depending on what apps you're using, I am usually able to get through a whole day at work starting at 6:30, and ending at 4, without needing to charge it, of course if I am watching videos or playing music, the battery will be used a bit more than if it's just locked not doing anything. ... show more

    • Definitely what I was hoping for
Color: Phantom Gray Size: 256GB
I am always leery about buying used electronics. You never know if you get the one that was barely used, and the person is just a serial upgrader every time a new model comes out. OR, if the item was traded in because it was malfunctioning, and wasn't spotted before being resold. Not the issue here so far. Tested every feature that I would actually use and it runs smoothly and quickly. From a full charge in the morning before I go to work, and with moderate usage throughout the day, it is generally down to about 80% by the time I go to bed (usually between 1:30 and 2:00am). I am upgrading from a much earlier model Galaxy and the camera (both still and video) quality is spectacular comparatively. Particularly in low light. Verizon SIM card transferred over without issues and that Samsung transfer app was a God send for getting all of my stuff (including pix, wifi passes, etc.....) over to the new phone. The lack of an SD slot makes me a bit nervous, but this one is the 256 gig model so hopefully, I won't have to do much relocating of files, images and videos over to my PC with the space that there is on here. Physically, the phone was in pretty good shape. Though there were a few minor scuffs on the back, the glass for the screen AND the camera lenses were flawless. And, I always use a case/holster anyway, way back since the old flip phone days. So, I will never actually SEE the body of the phone anyway. All in all, up to this point, I feel like the investment was good. There is 90 days worth of warranty so if I stumble across something that is a deal breaker, I can return it. If you are looking for a phone that won't cost as much as a cheap automobile, this "renewed" option may be something you can look in to. I will be trying it again when it is time to make another upgrade. ... show more
