NEW YORK (AP) — AT&T is reporting a fourth-quarter loss due to some hefty charges, but strong smartphone sales led to the company's best-ever quarter in activations.

Smartphone activations rose nearly 60 percent year over year, including 7.6 million iPhone activations.

The net loss amounts to $6.68 billion, or $1.12 per share, compared with year-earlier net income of $1.09 billion, or 18 cents per share. Adjusted profit was 42 cents per share.

Revenue rose 3.6 percent to $32.5 billion.

Analysts expected earnings per share of 43 cents on revenue of $31.99 billion, on average.

The Texas company says it plans to resume share repurchases this year.

In premarket trading Thursday, shares of AT&T Inc. fell 51 cents to $29.70.
