while

lines

billion

billion

, in 1995 and 1998 respectively.

Moreover

, mobile calls rose slightly and took one-third of the proportion of national and international fixed

lines

.

Additionally

, all mobile calls reached the nadir depicting just below 5

billion

in 1995, and

then

the proportion of mobile calls increased to approximately 9

billion

. It is conspicuous that Local

lines

touched the highest level of any category in any year, culminating at almost 90

billion

total minutes of call.

, there was a gradual decline in Local

lines

, and by the end of the period, it represented the same proportion as the initial figure.

Furthermore

, mobile calls tripled in 2002, compared to the figure supplied in 1999.
