LTE has quickly become the standard by which we measure our carriers. If we’re not on an LTE signal, we just aren’t happy. A new report from Open Signal (who measure their findings via metadata collected from their awesome mobile app) shows just how much we rely on LTE across the globe. Perhaps more importantly, their findings also give us a clue on which carrier is the best when it comes to LTE. What we find is that T-Mobile is absolutely schooling their competition.
