— Oct. 18: Verizon Communications Inc.'s wireless division added a net 1.5 million devices to contract-based plans in the third quarter, more than it has in many years. Analysts were expecting it to add about 900,000. Including non-contract devices, overall additions were the strongest in four years. Verizon Wireless got a boost from its new Share Everything plan, which made it cheaper for households to add wireless service to tablets and laptops.
The launch of the iPhone 5 at the end of the quarter also helped Verizon's numbers. It activated 650,000 units of the new model in just over a week. It activated 3.1 million iPhones of all kinds in the quarter, accounting for 46 percent of its total smartphone activations.
