I am going to purchase a new phone soon in the $300-$400 rang. I'm using Ting as a carrier so I need a device that supports t-Mobile's band 12. My leading contenders are the nexus 5x and the moto x pure edition. I like the size of the 5x better than the X PE but I think I would use the extra software features of X PE. I new to smartphones so any assistance will be appreciated. Thanks Charlie
