This

has split as local-fixed

lines

, National and International

lines

and Mobiles (all calls), and

minutes

of calls presented in billions.

considerably increased in the first five

years

, in 1995 to approximately 73

billion

, and peaked at 90

billion

in 1999.

However

, the figure has decreased from 2000-2002, respectively 85 , 80 and 73

billion

.

as well as

mobile calls continuously increased in the given period of time.

billion

mobile call users in 1995,
