those in rural and remote areas with contact to the outside world, reducing their sense of isolation and providing them with a tool to improve economic, social and cultural awareness.
Underlying Definitions and Concepts: Mobile cellular telephone subscribers
refer to users of portable telephones subscribing to an automatic public mobile telephone service using cellular technology, which provides access to the Public Switched Telephone Network PSTN.
The indicator is derived by dividing the number of
mobile cellular telephone subscribers by the population and multiplying by 100.
Limitations of the Indicator: The indicator provides no measure of the quality or
reliability of the telephone service.
Status of the methodology: The indicator is widely used in over 200 economies
around the world.
If accessibility is a main interest, then the number of
households with telephone (fixed or mobile) service may be more relevant especially for
countries which have large households.
