Call Waiting notifies you of an incoming call while you are already in another call, allowing you to put the first call on hold or reject the second one. This guide explains how to turn the feature on or off on Android phones.

Why Call Waiting matters

• Never miss critical calls even when you’re already speaking to someone.
• Choose whether callers are placed on hold or hear a busy tone.

Step 1: Open the Phone app

Tap the green phone icon on your home screen or app drawer.

Step 2: Open Settings within the Phone app

Tap the three‑dot menu (⋮) in the upper‑right corner and select Settings.

Step 3: Navigate to Supplementary services

Select Supplementary services (sometimes called Additional settings depending on your handset).

Step 4: Toggle Call Waiting on or off

Tap Call Waiting and use the switch to enable or disable.

Step 5: Alternatively: Quick dial codes

• Dial *43# and press call to enable.
• Dial #43# and press call to disable.
• Dial *#43# to check current status.

Summary

• Phone → Settings → Supplementary services → Call Waiting → Toggle ON/OFF.
• Alternatively, use the USSD codes *43# or #43#.

Additional information

• Menu names can vary between manufacturers (One UI, Pixel UI, MIUI, etc.), but the path is similar.
