Welcome to Vodafone Community
I use #43# to turn off call waiting, it works perfectly during the day and evening but overnight at about 3 AM it seems to re activate by itself.
Has anyone come across this, my Phone is a new Samsung A70.
Any ideas on a permanent fix would be appreciated.
Have you tried toggling call waiting off on your call phone settings? More time consuming but this will enable you to turn toggle back on when required.
I have tried to set call waiting both ways, via the toggle Turn off call waiting in Supplementary Settings and also #43#........both turn themselves hack on over night.
Are you on the latest Android software @Werlynne3?
By activating call waiting and switching this off again after a few minutes does this force the feature to stay switched off?
