The A51 was described as a 'Locked At&t device". it turned out to be locked to some other network. I since have seen quite a few negative reviews for Koala Stash external to BackMarket . I had purchased 2 phones several years and another one with this A51. I am very happy with these other purchases.

This phone saved my sanity. I was juggling my UK phone & a crappy US phone This is proof that using a Straight Talk/WalMart phone company shouldn't meet you have to settle for a bad phone or pay astronomical prices for a new one. Well done Back Market!

It's a nice phone, I am not so found of it yet, it is totally different than my last one. I am hoping it grows on me. I have been a motorola fan for years so this is taking some getting use to. The ease of ordering was great, phone is very nice.

The phone works great just didn't expect a crack to be in the middle of the screen. It said good condition was minor scratches and some wear from use but a crack is a little more than minor because the more you use the phone the bigger that crack gets.
