Hi, I know this question has been asked and answered many times but I cannot find any consistent information on it: what is the cheapest phone that can handle 4G LTE on all four major carriers and what would be a good price for it? From my research, I believe it is the Moto X pure.

As far as I know, there are only a few phones out there that can work on all networks. How's about a phone that is compatible on both T-Mobile and Sprint's 4G LTE? would there be more phones that would fit that description?

Many thanks!
