    • Amazing phone!!!
Color: Black Size: 32 GB
This phone shipped on time and was in perfect condition. The quality of the phone was pretty good not the best top of the line but it’s useful for call, text, scrolling through social media etc. basic stuff for your everyday use on your phone. The speed of the phone is okay it’s a little slow when you start it up but that makes sense because the phone is from 2020 is naturally it’s gunna slow down. The battery life on the other hand is pretty darn good! I would charge it for one day then it will last me 3-5 days with how I use it. The screen quality was really good no scratches and I’m able to see everything because how big the screen is on this phone. 10/10 I would recommend anyone to buy this phone if you just want to do basic stuff and don’t wanna break your wallet! ... show more

    • ITS NOT UNLOCKED FOR ANY CARRIER
Color: Black Size: GSM Unlocked
Claims it's unlocked for all carriers but it's not. Need the network code and Amazon is no help. I got it refurbished thinking they'd know how to go in and unlock the phone. Nope. The seller doesn't have the network unlock code or can even tell you the old carrier. They offered me $5 to help cover getting it unlocked or to send it back for a refund. Like. Wtf? Its a nice phone other than that. For good refurbish it looks nice. But this is ridiculous ... show more

    • Better than expected
Color: Black Size: 32 GB
UPDAT3: I unfortunately had to send this back because the screen started glitching like it was being touched, I hadn't dropped it or done anything in anyway to make it behave that way,, I now have a galaxy a12 through cricket.. I had a galaxy a02s that was constantly kicking me out of apps over storage being full even though I had an SD card in it, anyways I decided to buy this phone and was 99% sure I was going to have to return it but nope! It works so smoothly, it's sleek, finger print scanner is quick and one of my favorite parts. I go through boost mobile for my service, I saw some reviews said they could pop in their Sim card and it worked perfectly, that wasn't the case for me. I had to take mine to the store and have them use a code for it to work but it didn't take long and wasn't a hassle compared to the price and quality of this phone. I am so so happy with this purchase. ... show more

    • Samsung Galaxy A21 - Reliable & Excellent Value for the Basics
Color: Black Size: 32 GB
For a very affordable unlocked phone, the Galaxy A21 delivers exactly what you need without fuss. The GSM unlock is perfect for flexibility on most major carriers. While 32GB of storage is on the lighter side, it handles day-to-day tasks smoothly—social media, messaging, streaming, and calls are all reliable. The large screen is great for browsing and videos, and the battery life is impressively long, easily lasting a full day. The camera takes solid photos in good lighting. As a trusted Samsung device, it comes with a clean, user-friendly Android experience. If you need a dependable, no-nonsense smartphone for essential tasks at a fantastic price point, this is an outstanding choice. It’s the perfect budget-friendly workhorse. ... show more

    • Description is not accurate on phone carriers that don’t work on it.
Color: Black Size: GSM Unlocked
Phone is not truly unlock so read before, but I did read it and T-Mobile was not on the list so I got it. I was going to only use it as a back up and all I did when I got it was to made sure it work but didn’t try the SIM card because all the unlock phones I have purchased from Amazon have work without any problems . So when I did need to use it after roughly 6 months after purchase it didn’t work with my carrier and since it was past the return date I was stuck with a phone I can’t use and that they can’t do anything about it even tho T-Mobile was not on the list of carriers that didn’t work on the phone. ... show more
