    • 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

    • 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

Pro Solid built Very good cameras on both the front and the rear. Fast Batteries last all day Large display 20x9 aspect ratio means larger screen but still easy to hold. Call quality is very good. Speakers are loud and clear Supports quick charge Transferring my files and contact to the new phone was super easy and very fast using the built in software Cons My only issue with the phone is the display. It’s a 720p display which might be an issue for those who love to watch content like movies or tv shows on their phone. However I think the pros outweigh the cons drastically so having a 720p display doesn’t bother me at all. I think this a wonderful phone and I would recommend it to anyone who wants a good phone and save some cash in the process. ... show more

Después de usar este producto por un tiempo, tengo una perspectiva bastante clara. Si bien cumple con la mayoría de lo que promete y en general me ha sido útil, encuentro que hay algunos aspectos que podrían mejorarse. La calidad general es decente y ha resistido el uso regular, pero hubo un par de detalles, quizás pequeños, que me dejaron pensando si el diseño o la funcionalidad podrían ser más intuitivos o robustos en ciertas áreas. No es un mal producto en absoluto, y en muchas situaciones funciona muy bien. Sin embargo, si buscas la perfección en cada rincón, quizás quieras considerar si esos pequeños puntos son importantes para ti. En resumen, es un buen producto que hace su trabajo, pero con un poco de pulido adicional, podría ser realmente excepcional ... show more

    • Poorly renewed.
Color: Black Size: 32 GB
First 2 weeks phone worked great. Then the ringer and speakers stopped working. Not a big issue, vibration still works and Bluetooth headset is preferred. Unfortunately the screen cracked else it would have been a return then. Fast forward to today, 1 month of use, and the charging port no longer works, mic has stopped, Bluetooth is spotty, and phone is completely useless. It can make calls, but because the mic and speakers aren't working what's the point? ... show more

    • Good
Color: Black Size: GSM Unlocked
I’ve been using the Samsung Galaxy A21s for several months and I’m very satisfied. The battery easily lasts all day, the screen is large and clear, and the cameras take pretty good photos for this price range. Performance is smooth for daily tasks like social media, videos, and common apps. Ideal if you’re looking for a good phone without spending too much. ... show more
