It's only the 16GB model but it works well. I also have the LG G4 and some BLU Life Ones. Not a Samsung in the lot. Mostly because Samsung tinkers too much with the Android OS. So the BLU Life One only has 8GB internal and 1GB RAM but a 32GB 10 dollar memory card. It's unlocked and we went with Ting.com

I also put my LG G4 on Ting.com for the price here.

If I had to replace them? Another BLU.
