A:Answer There is no LTE version on Best Buy's website, but the stores are carrying the LTE version (at least for AT&T). In fact, one of the stores I went into only had the Frontier LTE version in stock and not any of the regular ones. You have to call each store individually, although depending on who answers the phone, they may be able to search the entire region and tell you which stores have which versions in stock (if any).
