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.

    • Definitely what I was hoping for
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

    • Huge upgrade from my previous phone
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

    • Amazon has no idea what customers actually receive- answer from customer support
Positive surprised about how it looks. Update: Just returned it and I am out $83 for shipping it back. Never again! Randomly shuts down. 2 days it works and crashes again. I had to reset it many times. Contacted even Samsung. Answer? Ship it back. No idea how Mobile Stream is refurbishing phones. But it looks like that they don't actually run the phones. - After reading this 5 star ratings, I thought maybe I got it all wrong. I ordered 2 S21 with 256GB this time I thought from Amazon. Seller was again a 3rd party. Anyway. Advertisement said factory unlocked and 256GB storage, from Amazon renewed store. - Seller Hybrid IT. Phones I got? 2 former AT&T 128GB phones! One even missing the SIM card tray. Useless if you need to use it as a actual phone. Contacted Amazon. Amazon support: We are sorry. Ship it back. - ABSOLUTELY NOT AGAIN. Amazon has no clue what sellers are actually shipping out - and what is worse than that - they don’t care! I explained that I will NOT again ship it back for now 2x $80 (insured package value shipping costs to me) and receive $1.Xx shipping costs refund. After a couple messages I get a free SIM card tray shipped for free (I should not have even to ask for one in the 1st place!) and 2x $30 refunded for phones complete out of specs n the 1st place because seller & I won’t pay $160 shipping costs. - I can honestly only warn Amazon customers to stay away from renewed products as long AMAZON has no clue - and worse - interest in what seller actually shipping out. To my question on how come they are not factory unlocked phones with 256GB - I received the answer from the seller: I don’t have them…… Seriously? Fraudsters all over the online market of Amazon! ... show more

Review Image by Lunita A. Leslie
Worst purchase ever! The phone was in "good" condition. Packaging was poor from the start. There were scratches all over the screen and small chips around the side of the phone. Now this was advertised as unlocked, why is it when I put my SIM card in it, it reads for about 30 minutes then shows "no SIM card inserted your device is unable to make calls or connect to mobile networks". I tried several working SIM cards and same issue. Now after using it for less than 24 hours the phone goes off and the dreaded blue screen pops up. This phone, if it was refurbished was done so poorly, as the model number states its dual sim but then the SIM tray is for 1 SIM. DO NOT BUY THIS PHONE OR ANYTHING FROM THIS SELLER ... show more
