Overall, the chart is divided into three categories: local, national and international, and mobile. As can be clearly seen from the chart, local calls remain the most popular category. In contrast, mobile calls account for the smallest number. By the end of the period, mobile and national and international call volumes had increased while the number of local calls decreased.
As for the calls made within local areas, this section’s bar has always been the highest. It started in 2001 at 72 billion minutes and reached its peak in 2005 at 90 billion minutes of calls. However, after achieving the highest point, the chart had falling from 90 billion to 72 billion until 2008.
The diagram indicator for national and international calls never took over local calls, and did not drop below mobile calls. In 2001 it started at 31 billion, and rose slightly to its top in 2008 at 61 billion in minutes of calls made.
As for the mobiles, which accounted a lowest numbers and uplifted as tediously as national and international calls, but with fewer statistics, beginning in 2001 with only 2 billion. The summit had got in the 2008, when the red bar indicated 46 billion.
