In telecommunication, Indonesia has sold part of the government's equity in its international communication firm (INDOSAT) and its domestic communication firm (TELKOM).  This latter privatization will result in millions of new phone lines all 
over Indonesia over the next few years.  In the area of cellular phone services, a number of private companies with some participation by TELKOM and 
INDOSAT, are currently operating in Indonesia.
