From October 17, only 8-digit numbers (as per new numbering system) are going to be active in Kuwait. Ministry of Communication (MoC) will be updating their system from 2 am to 5 am on Oct 17. So systems will be down. I am sure people have already updated their phoneooks and contact list.
People have to keep in mind that for Dial-up internet users, the 6 digit numbers like 8** *** should be modified by adding 1. Therefore the new modified number is 18** ***.
