Phone was in perfect condition and works great. I highly recommend the Galaxy A51. Handles most everything, 128GB is more than enough (and can expand if it's not), and takes pretty good pictures. Thanks!

The phones I bought for my daughters are in good shape, and once I factory reset them, they work great! It could have been my mistake about the factory reset. I spent an hour with Tmobile trying to get them to connect, and I was getting ready to send them back when I did the factory reset, and I noticed that they seemed to be working.

I bought an A51 in 2021, unlocked. On ebay. However, it wasn't and I was forced to keep some expensive plan I hated. Luckily it broke, but I really liked this phone. Dies everything I need and will be a long while before it stops upgrading. Great price, no scratches, no dents. And...yes 💯 percent unlocked.

BUYER BEWARE: I previously ordered a phone from this seller which had to be returned because it was the wrong phone (Galaxy A51 5G not A51 4G) and it wasn't in excellent condition which it was supposed to be. Because the seller only offered returns I was forced to return the phone, and not exchange it, even though the seller still had the same device listed for sale. A few weeks later I tried ordering another phone from this same seller (it was the only option for an A51 that was above fair condition). That phone also had to be returned because it was not unlocked as stated. Neither refund was processed by the seller within the specified time frame (at the time of writing the seller has had the second return for 4 business days). Backmarket pushed through the refund on the fisrt device and I have contacted them about issuing the refund for the second phone.

So far, so good. Phone arrived in seemingly almost new condition and working flawlessly so far. Charging cable sent was a USB Type C at both ends, so I will need to get an adapter for AC or PC charging.
