Verizon's quarterly revenue rose 6.8 percent due to an increase in subscribers who pay for services after use, and a rise in average revenue per account as users added more devices to shared data plans.

The company, however, reported a loss of $2.15 billion, or 54 cents per share, for the fourth quarter compared with a profit of $7.92 billion, or $1.76 per share, a year earlier, mainly due to valuation of benefits plan and pension adjustments.
