What does CSID mean or stand for ?
CSID is also known as Caller ID nowadays and everyone who has a mobile phone is familiar with this.When you get an incoming call on your cellular phone,the person who is calling you ,their number gets displayed on your screen.
Even in landlines,we can attach a device to identify the caller subscriber ID but most of us do not use the landlines so often.
There are certain privileged people like heads of state and VIPs who can opt for a plan from the Department of Telecommunications and their mobile service provider to mask and hide their number.These number that are masked will not show up on another persons phone and will only appear as ” private” or “no number”.
