§ Service revenue growth improved to 6.4%* (Q4: 5.3%) as voice revenue returned to growth and regulatory impacts reduced. Excluding regulatory drags including MTR cuts, roaming price caps and an increase in service tax, service revenue grew 7.7%* compared to 10.2%* in the fourth quarter of the prior fiscal year. The slower pace of growth mainly reflects the reversal of the leap-year effect and lower intra circle roaming revenues.
§ Data browsing revenue growth of 22.3%* slowed from the pace of prior quarters, reflecting lower customer growth. Our active data customer base increased to 69.7 million customers from 66.8 million one year ago. The 3G / 4G customer base grew to 32.3 million, up 46%, and smartphone penetration in our four biggest urban areas is now 54%. Voice revenues returned to growth as competition eased, despite lower average minutes of use per customer. Total mobile customers increased 1.4 million giving a closing customer base of 199.4 million.
§ We added 3,300 new 3G sites in the quarter, taking the total to 59,000 and our population coverage to 96% of target urban areas. We have 9,700 4G sites with coverage of 45% of our data revenues across five key circles. We expect 4G coverage to increase to over 60% of our data revenues by year-end, ahead of the upcoming spectrum auction.
