Unlike the AT&T/T-Mobile merger which regulators rejected, the proposed T-Mobile/Metro PCS merger will get quick DOJ and FTC approval. Why? While the AT&T merger would have eliminated the largest low-priced competitor from the marketplace and increased industry concentration at the top, the Metro PCS merger enhances competition by merging two weak carriers to hopefully create a more viable #4 carrier, that can better compete with Verizon and AT&T.
