Right. Thank you, Justin. Good morning, everybody. Before I get into the details, I'll comment first on the overall results for the quarter and the year. The results and trends for the fourth quarter are fairly consistent with what we saw for the year, particularly the prior 2 to 3 quarters, strong operating cash flows and profitability improvements over the comparable period of 2011. These improvements were not unexpected, having seen them in the past few quarters, but we're glad to see them nonetheless.
Driving the improvements this quarter were the same primary factors: elimination of duplicate expenses and cost reductions in U.S. wireless; revenue growth in a number of island markets; and margin improvements in Bermuda, following the integration of the 2 businesses in that market.
While we are pleased by these improvements, our U.S. wireless operation continue to experience revenue declines due to erosion of our postpaid subscriber base.
So with that, let me just turn to some specifics, starting with U.S. wireless. First, I just wanted to mention that despite the strategic realities, as we see them in the recent agreement to sell that unit, we -- I wanted to mention that we're proud of a lot of what our team at Alltel has achieved. We were able to stabilize the overall subscriber base through steady gains in the prepaid market. And we were also able to dramatically improve the post conversion customer experience overall.
So with that, let me get into some of the usual details. For the quarter, we had nearly 40,000 prepaid subscriber gross additions and approximately 9,500 prepaid net adds, both of which were down from the third quarter, but up significantly over the prior year.
Postpaid gross additions came in just shy of 30,000 for the quarter, resulting in a decline in the postpaid subscriber base of a little more than 7,000. Gross additions rose as expected because of the holiday selling season, but not by enough to counter still-high churn.
So that churn, postpaid subscriber churn first, was approximately 2.9%, up from 2.7% in the third quarter and down from 2.6% 1 year ago. Part of this was due to high contract expirations, but we were still somewhat disappointed by the results and continue to struggle to overcome our unique operating experience -- circumstances.
Blended subscriber churn for the fourth quarter was 3.8%. That's up from 3.7% in the third quarter and 3.4% 1 year ago. Postpaid ARPU was $55.16, and that compares to $54.52 in the third quarter and $54.43 1 year ago. And that's due mainly to increase data revenue and customers trading up from smaller usage plans to our unlimited plans.
Overall, subscriber ARPU was $46.79 compared to $46.87 in the third quarter and $48.56 1 year ago. The decline in overall ARPU year-on-year was primarily driven by the shift in mix to a higher concentration of prepaid subscribers in 2012 and, to a lesser extent, by a reduction in ETC funds received in the second half of the year.
On smartphone adoption, we ended the quarter with nearly 41% of our postpaid base on smartphones. About 64% of total postpaid device sales in the quarter were smartphones, and that compares to 49% 1 year ago and 55% in the third quarter. So similar trends to what you've seen elsewhere in the industry. And a little over 8% of the postpaid subscriber base upgraded in the quarter.
Turning to wholesale and U.S. wireless. Wholesale roaming revenues were basically flat year-on-year and down as expected from the third quarter due to typical seasonality.
Voice and data volumes declined approximately 10% to 20% in most areas from the busy third quarter. As noted in our release, we did see an increase in overbilled activity in 2012, particularly in the Alltel markets. Although for this period, that was largely offset by arising data volumes.
For 2013, we expect that sort of overbilled activity to continue, although it is difficult to predict the rate or level of impact. On the positive side, we expect to build or upgrade more wholesale-driven sites in the Western United States in 2013. It should begin to have a positive effect on wholesale revenue by the end of this year and into 2014.
In our international operations. International wireless revenue showed solid gains due to subscriber growth and some improved economic activity in a number of our island markets.
In Guyana, wireless subscribers increased slightly from the third quarter and 1 year ago, with subscriber ARPU increasing modestly as well. In wireline, as reported, total wireline revenue was flat, but it's probably worth getting into a little of the details because there are a number of different trends beneath that number.
In the U.S., wholesale wireline revenue, such as carrier backhaul, showed solid growth. And this is before completion of our major stimulus funded fiber builds. As to those builds, they're proceeding well, with over 700 miles completed and the balance of approximately 500 miles on track to be completed in the second half of this year.
And it's important to note, when we say completed that, that means that fiber is up, in a lot of cases it's lit, but we have not turned on customers in most cases until the entire network is finished, and so we're looking forward to the benefit to revenues. It'll be relatively small for ATN, but it'll be a positive when that's all lit up by the end of this year. And towards that end, we've signed up a number of customers, including tools and government agencies or service when the sites and routes go operational.
Sticking to U.S. wireline for a moment, the traditional enterprise select business is enduring some of the challenges reported nationally with enterprise unit access line equivalent to pricing falling faster than volume growth.
We also see pressure on the traditional copper-based services by higher capacity services, including pressure we're providing ourselves as we cannibalize that with new fiber.
Churn, while up slightly, remains very low thanks to strong customer service and network quality. But again, it's the -- the pricing pressure in the SME market is shifting a lot of our focus to larger accounts.
Internationally, wireline voice revenue declined. International Long Distance in Guyana has suffered from increased bypassed activities, which we believe the authorities need to do more to combat, as it is plainly unlicensed and also deprives the country of critical tax revenue.
On the other hand, broadband subscribers and total data revenue in that market continue to grow rapidly. And we are proud of the pace of growth and the availability and quality of the broadband infrastructure in Guyana, which our team has brought about.
In future periods, we look forward to contributing to that country's driving economic growth and efficiencies in the commercial and education sector.
So in summary, this was another strong quarter and year in the areas that ultimately matter most to us and to shareholders, which is profitability and cash flow. I should add related to that, that we did not lightly come to the conclusion that the time was right to sell a very important operating unit. That is a relatively rare occurrence at ATN, as we like to operate businesses for the long-term and to deploy operating cash flow to continue to grow the company overall.
But our charge to investors is pretty clear. We have to make those strategic decisions based on an objective analysis of the prospects of the business, not our hopes or personal preferences. And I'm proud of our team's track record in putting the stockholders first and delivering steady and strong returns over time.
If we invest according to our overall plan and approach, those events should remain infrequent, but they will undoubtedly continue to occur from time to time as markets and industry shift.
So with that, I will turn the call over to Justin for a more detailed financial review.
