NEW YORK (AP) — Verizon added more than 1.4 million long-term wireless subscribers in the second quarter, with strong gains in both smartphones and tablets, the company said Thursday.

Verizon Communications Inc. CEO Lowell McAdam said the company’s wireless profit margins remain consistent with the past several quarters. Verizon is the nation’s largest wireless carrier. The second-quarter gains cited are for retail post-paid plans, which are the lucrative ones offered to good-credit customers and include those on two-year service contracts.

The company plans to report its second-quarter earnings on July 22.

Shares of the New York-based company slid 13 cents in after-hours trading to $49.51. The stock had closed up 74 cents at $49.64.
