Does Call waiting still work over Wi-Fi calling or VoLTE?

In most cases yes, since the setting is tied to your carrier account rather than the connection type. If it fails only on Wi-Fi calls, test with mobile data or VoLTE disabled to isolate whether the network or the phone setting is responsible.

Does turning on Call waiting cost extra?

The feature itself is usually free, but check with your carrier since some prepaid plans bundle it differently. The setting inside Carrier call settings ➔ Additional settings only toggles the function, it does not change your plan.

I have two SIM cards, do I need to set Call waiting twice?

Yes. Each SIM has its own entry under Additional settings, so select the SIM card first before toggling Call waiting, then repeat the steps for the second SIM if needed.

What happens to the second caller when Call waiting is off?

The second caller either hears a busy tone or gets redirected to voicemail, depending on your carrier configuration, and no notification sound appears on your Realme phone during the active call.

Realme: Turn Call Waiting On or Off

If a second call slips through without any notification sound while you are already on a call, Call waiting is disabled on your Realme phone. Depending on your carrier, this feature is often active by default, but it can silently switch off after a system update or a SIM swap. Missed calls during an active call almost always trace back to this one setting.

Turn Call Waiting On or Off auf Realme

Call waiting on a Realme phone signals a second incoming call with a short notification sound while you are already talking. Without it, the caller either hears a busy tone or gets forwarded to voicemail, and you never see the attempt.

The setting sits inside the carrier call settings, not in the general phone menu, which is why many people cannot find it after a reset or a new SIM card. It also applies separately to each SIM slot on dual-SIM devices, so one line can have it enabled while the other does not.

To check or change it, open Phone ➔ Menu ➔ Settings ➔ Calling accounts ➔ Carrier call settings ➔ Additional settings. If you use two SIM cards, pick the correct card first, then toggle Call waiting on or off.

Leave it on if you want to know about a second caller during an active call. Turn it off if you prefer the second caller to go straight to voicemail or a busy signal without interrupting your current call.

Frequently asked questions

This usually means your carrier controls the setting on the network side rather than through the phone. Contact your provider to confirm whether Call waiting can be managed from their end or reactivated remotely.
