PART I MOD . Our MOD revenues increased by 9.9% from NT$0.9 billion in 2009 to NT$1.1 billion (US$37.5  million) in 2010. This increase was mainly due to an increase in the average revenue per user. In addition, since  2010, MOD revenues include billing fees and advertising revenues, which was previously accounted for under  domestic other services.  Revenues from our mobile communications business segment comprised 43.6% and 44.0% of our revenues  in 2009 and 2010, respectively. Revenues from our mobile communications business segment increased by 2.9%  from NT$86.5 billion in 2009 to NT$89.0 billion (US$3.1 billion) in 2010. This increase was principally due to  the growth of mobile VAS revenue and handset sales revenue offsetting the decline of mobile voice revenue over  years. The growth of mobile voice traffic due to the general recovery of the economy in the ROC partially offset  the impact from the mandatory tariff reduction, which helped slow down the decline of the mobile voice revenue  in 2010.  Mobile services.  Revenues from our mobile services comprised 36.0% and 36.1% of our revenues in 2009  and 2010, respectively. Revenues from our mobile services increased by 2.3% from NT$71.4 billion in 2009 to  NT$73.1 billion (US$2.5 billion) in 2010 due to the growth of mobile VAS revenue from NT$8.4 billion in 2009  to NT$ 11.1 billion (US$0.38 billion) in 2010, offsetting the decline of mobile voice revenue. The growth of  mobile traffic volume due to the general recovery of the economy in the ROC also helped slow down the decline  in mobile voice revenue.  Sales of mobile handsets and data cards.  Revenues from our sales of mobile handsets and data cards  comprised 7.6% and 7.9% of our revenues in 2009 and 2010, respectively. Revenues from our sales of mobile  handsets and data cards increased by 6.1% from NT$15.0 billion in 2009 to NT$15.9 billion (US$0.6 billion) in  2010. This increase was principally due to the strong sales of mobile smart phones and the general recovery of  the economy in the ROC.  Internet revenues comprised 11.9% and 12.1% of our revenues in 2009 and 2010, respectively. Our  revenues attributable to our internet business increased by 3.5% from NT$23.7 billion in 2009 to NT$24.5 billion  (US$0.8 billion) in 2010. The increase was mainly due to a 1.6% increase in the number of our total HiNet  broadband subscribers from approximately 3.5 million as of December 31, 2009 to approximately 3.6 million  as of December 31, 2010. Our HiNet subscribers remained at approximately 4.1 million subscribers as of  December 31, 2009 and 2010 because the increase of our HiNet broadband subscribers was offset by the decrease  of HiNet dial-up subscribers. As of December 31, 2010, approximately 82.0% of our broadband customers were  also HiNet subscribers, using HiNet as their ISP.  Our international fixed communications revenues increased by 1.9% from NT$15.2 billion in 2009 to  NT$15.5 billion (US$0.5 billion) in 2010. This increase was mainly due to the increase in revenues from our  international leased line services and international data services.  International long distance telephone services.  Our international long distance telephone revenues remained  constant at NT$12.9 billion (US$0.4 billion) in 2009 and 2010 because the decrease of the unit price was offset  by the growth in both the traffic volume of calls using calling cards and the wholesale of the traffic from 2009 to  2010. Our international settlement revenues decreased from NT$3.5 billion in 2009 to NT$3.2 billion (US$0.1  billion) in 2010. This decrease was primarily due to the appreciation of NT dollars.
