Carrying a second SIM, or moving between networks while travelling around the Gulf? Vodafone Qatar’s call waiting uses the same *43# code you’d dial on any other GSM line, so nothing about managing overlapping calls changes when you switch.
Quick answer
Dial *43# to activate, #43# to deactivate, and *#43# to check whether it’s already on.
One code, works everywhere
Because *43# is a GSM-standard code rather than a Vodafone-only service, the same sequence also works on Ooredoo Qatar and on virtually any network worldwide — useful if you carry a second SIM or travel often and don’t want to remember operator-specific instructions. Prefer menus? Most phones expose the same switch under Settings → Calls → Call waiting.
Switching between calls
A beep during an active call flags a second caller. Press the call button to hold the first and answer the second; press again to swap back.
Want calls blocked or redirected instead of just managed? See Vodafone Qatar call barring or call forwarding.
*43# is the GSM/3GPP standard supplementary-service code, verified against Vodafone Qatar’s official FAQ, August 2026.

Frequently Asked Questions
Is call waiting free on Vodafone Qatar?
Yes — activating, checking, or cancelling is free. Only the calls themselves are billed at your standard tariff.
Does it work on prepaid and postpaid?
Yes, it's a network-level feature supported on both.
Will it still work when I'm roaming?
Yes, as long as the visited network supports call waiting (almost all do) — calls answered abroad are billed at roaming rates.
Is the code different on Ooredoo Qatar?
No, *43# is identical on both Qatar operators since it's a GSM standard.
Does carrying a second SIM affect this?
No — each SIM manages its own call waiting independently via the same *43# code.
