This is for a moto x pure. But I have had three other phones act the same way. One mintue I have lte, the next e, and then most of the time h. It connects best when I lay down, but when I sit up it drops and slows. Location chanes things, but I can stay put and it still jumps between e, lte, and h.

Oh boy. We don't have account access here, but you're welcome to give T-Force a shot at this one. You can get in touch with them through the Twitter or FB links below. Most likely, it'll be the same answer you got from Prepaid, but T-Force can take a look at this for you.
