The chart below shows the total number of minutes (in billions) of telephone calls, provided into three categories, from 1995-2000

The graph illustrates the amount of time of phone call by local - fixed line, national and international - fixed line and mobiles (all calls) between 1995 and 2002.
Overall, while mobiles and national and international tended to rise over the years, local showed a decrease after the prosperous period in 1999. Mobiles and national and international trended to increase slightly during the periods. Mobiles provided the least total of minutes about 3 billion in 1995, and this development still kept under 10 billion until 1998. In contrast, the number of minutes of national and international reached to approximately 40 billion in 1995. There was a stable climb to 50 billion in 1999 and this number had five times compared to mobiles in the same year. From 2000 to 2002, both had a minimal change before hitting to over 60 billion for national and international, and 45 billion for mobiles.
Local took the dominant part in the total number of minutes, more than 70 billion in 1995 climbing up to the highest peak in 1999 at 90 billion. A decline after 3 years remained exactly the number at the first period.
