Ever since it lost the exclusive right to sell the iPhone in the United States in 2011, AT&T has touted a key advantage that its network has over Verizon’s: the ability to talk on the phone while using data from another app simultaneously. While simultaneous voice and data became possible on Verizon once the company’s 4G LTE network went live, hardware limitations on iPhone 5 prevented customers from being able to use it. More than three years later, Verizon iPhone customers will finally gain the same feature, as long as they’re using one a new phone.
