(Adds shares, details on churn rate)
NEW YORK, July 25 (Reuters) - AT&T Inc's quarterly profit topped Wall Street estimates on Tuesday as the No. 2 U.S. wireless carrier introduced new promotions bundling video with phone service that helped to attract customers.
Its shares rose 2.5 percent to $37.12 in after-hours trading.
Net income attributable to AT&T rose to $3.9 billion, or 63 cents per share, in the second quarter ended June 30, from $3.4 billion, or 55 cents per share, a year earlier.
Excluding some items, earnings per share were 79 cents, ahead of analysts' average estimate of 73 cents per share, according to Thomson Reuters I/B/E/S.
Revenue declined to $39.8 billion from $40.5 billion in the year-ago period, hitting analysts' average estimate.
Churn, or customer defections among phone subscribers who pay a monthly bill, was 0.79 percent, the lowest in the company's history, AT&T said. (Reporting by Anjali Athavaley; Editing by Bill Rigby)
