To begin with, minutes made by local fixed line calls type were 72 billions in 1995, followed by a steady growth before hitting a peak of 90 billions in 1999 .(<--Reword to: "In 1995, the number of minutes of local fixed line calls was 72 billion. This number steadily increased to a peak of 90 billion minutes in 1999.") Whereas, in next 3 years, a decline was observed before reaching a final figure of 72 billions.(<--Reword to: "However, from 2000 to 2002, there was a decline in the number of minutes back down to 72 billion.")

Considering minutes made by national and international fixed line, graph illustrates that it was the second most popular type and linear growth was observed throughout the period, as 37 billions made in 1995 and 60 billions in 2002(<--Reword to: "Throughout the period there was a steady increase in the number of minutes spent on national and international calls. In 1995, 38 billion minutes were spent on these types of calls. By 2002, that number was 61 billion.")

However, data about mobile calls shows that it was not popular in the first 4 years; only 3 billion minutes spent in 1995 followed by a slight increase before displaying tremendous acceleration in the last 4 years, reaching a final number of 45 billion minutes.

Overall, it appears that local fixed line calls have been the most popular type throughout the period, whereas the number of minutes spent on mobile calls swelled tremendously with time.
