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. 

## Mobile communications 

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 

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. 

## International fixed communications 

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.
