Dialled *43# but still not hearing the beep? Some phones need call waiting switched on in two places at once — the network side via the code, and the handset’s own call settings — and Zain Kuwait’s own guidance flags this as the most common reason the feature seems not to work.
Quick answer
Dial *43# to activate, #43# to deactivate, and *#43# to check status.
The two-switch issue
*43# controls the network-level setting; many phones also carry their own call-waiting toggle under Settings → Calls. If the network side is confirmed active via *#43# but you’re still not hearing a beep, check the phone’s own settings menu next — both need to be enabled together on some handsets.
How it works once both are on
A beep during an active call signals a second caller. Press the call button to hold the first and answer the second; press again to swap back.
