Ooredoo Kuwait’s call waiting runs on the same *43# code used on virtually every GSM network worldwide — nothing carrier-specific to learn, and nothing that changes if you travel or switch operators.
Quick answer
Dial *43# to activate, #43# to deactivate, and *#43# to check status. Free on prepaid and postpaid.
How it works
A beep during an active call flags a second incoming caller and shows their number. Press your call button to place the first on hold and answer the second; press again to swap back — neither call is dropped.
Identical across Kuwait’s operators
Zain and STC Kuwait use the exact same *43# code, since call waiting is defined by the GSM standard rather than built by any one operator.

*43# is the GSM/3GPP standard supplementary-service code, verified against Ooredoo Kuwait’s official support guidance, August 2026.
