I am very familiar with GigaByte in the realm of PC components. They make everything from motherboards to graphics cards. They are usually high quality products, and while I am an Asus fanboy, I would not hesitate to recommend components made by them. And the I stumbled upon this: Gigabyte GSmart Guru GX Dual SIM LTE Specs Technical Datasheet PDAdb.net. It does not support LTE bands for North American carriers (to my knowledge at least AT&T and Verizon 700Mhz networks). But it does have a feature I am dying for in phones in America: Dual SIM support. The primary SIM slot supports LTE, while the second SIM slot supports 2G/3G/HSPA. So far, this is almost as cool the Xbox One I got for Christmas!!
