I have call waiting active on my Nokia 6303.
Every time someone calls it shows as call waiting.
Some times when someone is calling it shows up on the other persons phone as call waiting, and sometimes it don't.
I want call waiting active, but I don't want the other person to know that I am on a call..
On my old Nokia 5310.. the other person would not know that I am in a call, but I have the option of switching between calls hence call waiting is active.
Is it the mobile phone? Network or just luck lol
