Zoom on iPhone: How to Turn Your Microphone On/Off

Once you have started or joined a Zoom meeting using your iOS device such as iPhone/iPad, follow the steps below to connect audio to the meeting. 

1. Touch the meeting window to bring up the in-meeting option tools. 

2. Select the Join Audio icon option. From here, you can choose the following:

   • Call using Internet Audio: Uses your iOS speaker and microphone.

   • Dial in: Prompts you to dial into the meeting. This option is not available if the host selected Computer Audio only when scheduling the meeting. 

   • Call My Phone: Calls your phone to connect audio. This requires a subscription to an audio conferencing plan.

     

Tap Mute/Unmute in the bottom-left corner of the meeting controls toolbar as needed to control your microphone. 

Optional: In the meeting controls toolbar, tap the More ··· icon, then tap Disconnect Audio if you need to join the audio with a different method. 

To make sure that your microphone is working properly, you can test your audio both before and during your meeting.  

First, in a mobile browser, go to http://zoom.us/test. Next, launch the Zoom mobile app to join the test meeting.
