If ATT acquires Tmobile. They will be able to control prices a lot better than without Tmobile. Why? ATT and Verizon already own most of the network backhaul and core fiber wirelines in America. They rent and charge fees for other mobile networks to use their backhaul and interconnecting them. Sprint and others(MetroPCS, etc) will be the only ones left behind without a core network and they will have to raise their prices if ATT/Verizon agree to raise their fees. That is a lot of leverage. ATT/Verizon already dislike Sprint for having cheaper plans. Ironically, most Verizon customers swear by God that Verizon is the cheapest deal. LOL.
