"While ISDN and prepaid phone lines increased, the number of post paid subscribers declines by 5.1% - from 2,839,000 to 2,694,000."
I can understand that some people still using dial-up, although many other people don't.
The ISDN I'm not so sure about?
Would this service be used for the same reason that are still a lot of dial-up users in my area?
People not able to afford broadband, see no need to change to broadband,
areas where broadband are not available?
Would this be private or business that would boost ISDN.
I honestly thought that broadband replaced ISDN. I did not think it was still on offer!
I think I last used / saw ISDN in 2002 when I cancelled my 128KB line and Telkom came to remove my / their modem.
