Good morning. I'll begin with a few comments on customer results, shown on Slide 6. Postpaid gross additions for the first quarter of 2015 were 200,000, an increase of 2% from 197,000 a year ago. Postpaid churn for the quarter was 1.48%, down from about 2.3% last year. I'll say more about postpaid churn in a minute. Due to both higher gross additions and improved churn, we achieved postpaid net additions of 9,000 for the quarter, a significant improvement from the net loss of 93,000 postpaid customers a year ago.
The mix of our postpaid gross and net additions in the first quarter is shown at the bottom of the chart. Gross additions comprised 66% handsets and 34% connected devices. Net additions were driven by smartphones and, to a greater extent, by connected devices. Prepaid subscriber results, 12,000 net additions, were relatively flat year-over-year while churn improved to 5.8%.
The next slide has a chart showing the trends in the postpaid churn rate over the period beginning in January of 2013 and continuing through March of 2015. As we've been reporting over the past couple of quarters, churn peaked at 2.4% in February of 2014 and has continued on a steady downward trend since that time, decreasing to 1.48% for the first quarter of 2015.
Slide 8 shows the positive trends in smartphone sales and penetration. During the first quarter, we sold 403,000 smartphones, which represented 86% of total handsets sold, driving smartphone penetration to 67% of our base of postpaid handset customers, up from 56% a year ago. So at the end of the first quarter, we still had about 1/3 of our postpaid customers with basic phones. And as Ken said, we intend to work aggressively to upgrade these customers to smartphones and drive additional data usage revenues. During the first quarter, we also sold 72,000 connected devices.
As Ken already mentioned, we continue to have good progress in the adoption of 4G technology. On the network front, we completed wave 4 of the deployment early in the first quarter of 2015 and are now covering 94% of our customers. In addition, at the end of the quarter, 64% of our postpaid customers have 4G-capable devices. This means that 64% of our customers have devices that are capable of providing them with a high-speed 4G data experience on a best-in-class network.
We believe that the higher penetration that we're seeing for smartphones and connected devices, when combined with increased adoption of our Shared Connect data plans, is allowing us to capitalize on the continuing growth in data consumption. The penetration on our Shared Connect plans is now 56%, up from 47% last quarter. That increased penetration for smartphones and connected devices and Shared Connect plans is having a positive impact on our revenue trends, as shown on the next slide.
Postpaid ARPU, as reported, was $54.87 for the first quarter. That's down about 4.7% year-over-year. Although increased smartphone penetration and data usage clearly have had a positive impact on revenue, we've also seen downward pressure associated with both industry-wide price competition over the last few quarters and discounts on normal service plan pricing for customers who activate their own device or purchase one under an equipment installment plan. These equipment-related discounts, which are shown in the table at the bottom of the slide, effectively shift some revenue from service revenue to equipment sales revenue. If normalized for that shift, ARPU for the first quarter increased by 3% year-over-year and was essentially flat sequentially.
Postpaid average revenue per account or ARPA, as reported, was $134.94, up 2.2% year-over-year. When normalized for the equipment-related discounts, ARPA grew at the more robust rate of 11%. Also remember that the ARPU and ARPU metric shown here are calculated using service plan revenues, and therefore, do not reflect the monthly equipment billings to customers who have equipment installment plans. In the first quarter, these equipment billings totaled about $47 million, which is equivalent to $3.66 per average postpaid customer or $9 per average postpaid account.
The next slide in the deck provides some summary statistics related to equipment installment plans. I'll highlight a couple of the line items. For the first quarter, EIP sales were 39% of total postpaid devices sold and resulted in $68 million of recognized revenue. Both devices sold and the related revenue were negligible amounts in the previous year. EIP-related bad debts expense for the quarter, which we determined using our historical accounting method, was $5 million. And acknowledging that it is still early, we haven't observed any unusual default activity among equipment installment plan customers.
Moving on. Total operating revenues for the first quarter were $965 million, up $39 million or 4% from $926 million a year ago. The increase was driven primarily by higher equipment sales revenues, reflecting the growth in equipment installment plan sales. Total service revenues were $828 million, down $26 million or 3% from last year. The principal factor in the decrease was lower retail service revenues. There was an increase in the number of customers year-over-year, but the impact of that growth was offset by the decrease in reported ARPU discussed earlier. Inbound roaming revenues of $40 million decreased $10 million or 20% due to both lower volumes and rates. Tower rentals for the quarter, largely representing our remaining tower portfolio following the sale completed in January, were $14 million, up 9% year-over-year. And ETC revenues included in other were flat year-over-year at $23 million as the FCC's phasedown of Universal Service Fund support remained suspended.
Our overall financial performance for the quarter was quite strong, as shown on the next slide. Operating cash flow for the quarter was $167 million, up significantly from $79 million a year ago. Note that this measure excludes the gains associated with the tower sale and license exchange that were mentioned earlier. Several factors contributed to the overall improvement. First, as I just discussed in more detail, total operating revenues grew by $39 million or 4% year-over-year. In total, cash expenses of $798 million decreased by $49 million or 6% year-over-year. System operations expense increased by $10 million, primarily due to outbound roaming expense. However, more than offsetting that increase, cost of equipment sold fell by 12%, driven by lower gross additions and a lower, that is improved, upgrade rate. And SG&A expenses fell by 7% due to lower sales commissions on reduced volume and lower consulting and outsourcing costs related to the billing system conversion last year.
I also want to use this chart to highlight our true operating performance for the quarter. As you can see at the bottom of the slide, our operating income, excluding the nonrecurring gains in both periods, dramatically improved from a loss of $89 million last year to income of $20 million this year. Adjusted EBITDA, shown next, incorporates the earnings from our equity method partnerships and imputed interest income from EIP transactions. Adjusted EBITDA for the quarter was $209 million, up 79% from $117 million last year, driven largely by the increase in operating cash flow.
Our estimates for full year 2015 are shown on Slide 14 of the presentation. For total operating revenues, the range remains at $4.0 billion to $4.2 billion. For operating cash flow, we're increasing the range by $50 million at both ends to $400 million to $500 million. This increase balances the positive performance in the first quarter with the fact that we still have an intensely competitive market with a lot of pricing uncertainty as well as the fact that we believe we will need to be aggressive to achieve our overall subscriber growth goals. In order to generate the growth we want, we expect acquisition costs to be higher over the remainder of the year. The increase for operating cash flow ripples through to the guidance for adjusted EBITDA, which incorporates the earnings from our equity method partnerships and interest income. The updated guidance for adjusted EBITDA is $580 million to $680 million. And finally, capital expenditures are still expected to be about $600 million.
Before I conclude, I want to make just a couple of comments about U.S. Cellular's balance sheet. Overall, I'd say the balance sheet is in good shape. We saw a continued improvement in both customer accounts receivable and inventory balances over the course of the first quarter. As of March 31, cash and equivalents totaled 307 -- sorry, $337 million, up $125 million from the year-end level. In addition to the existing cash and equivalents, we have about $280 million of unused borrowing capacity under our revolving credit agreement. And in January, we entered into a new term loan agreement that provides additional borrowing capacity of $225 million. We believe that these resources, together with expected cash flows from operating activities, provide sufficient liquidity and financial flexibility to meet our day-to-day operating needs for the foreseeable future.
And now I'll turn the call over to Vicki Villacrez to discuss TDS Telecom. Vicki?
