Hey there! Sending a voice message is super convenient when you need to share an important recording like a meeting or a lecture with a friend for review. Here's how you can send voice messages on your iPhone.
Step 1: Open the Voice Memo app on your iPhone.
Step 2: Tap on the red circle button to start recording, and when finished, tap Done.
Step 3: Enter a name for the recording and tap Save.
Step 4: Tap on the recorded audio and select the share icon at the bottom left, then choose Message to send via text.
Step 5: Enter the phone number and tap Send to dispatch.
Note: If the recipient doesn't use an iPhone, iPad, or iPod but has a compatible smartphone with multimedia messaging service (MMS) support and has this service activated, they'll still receive the message normally. The audio file format is m4a, so the receiving device needs a suitable app to play this message.
