Audio recording not available in iMessage: why the button disappeared

For years the audio message control was a microphone icon at the right-hand end of the text field, held down to record. Recent iOS versions moved it into the plus menu to the left of the field instead.

Tap the plus, and Audio is in the list alongside Camera, Photos, Location and the rest. Tap it and recording begins, then send with the arrow.

If you updated iOS recently and the button vanished, this is almost certainly what happened. Nothing is broken and no setting was changed.

If tapping Audio produces an error or nothing at all, check that Messages is allowed to use the microphone. Settings, Privacy and Security, Microphone, and confirm Messages is switched on.

If Messages is not in that list, the permission has never been requested. Try recording once to trigger the prompt, and accept it.

Also check Screen Time. Under Content and Privacy Restrictions, microphone access can be locked at the device level, which is common on a phone that was set up for a child or issued by an employer. A locked setting appears greyed out rather than off.

Audio messages travel over iMessage. If you are texting an Android phone, or iMessage is unavailable for that conversation, the option may not be offered at all.

The quick check is bubble colour. Blue is iMessage. Green is SMS or RCS, and the feature set is different. If audio works in one conversation and not another, this is why, and there is nothing to fix.

Also confirm iMessage itself is on: Settings, Apps, Messages, and check the iMessage toggle. It can switch itself off after a SIM change or a network problem.

By default, iOS deletes audio messages two minutes after you listen to them, to save space. People often read this as a bug or as the feature being unavailable.

Settings, Apps, Messages, Audio Messages, Expire, and change it to Never. Do this before you need it, because it does not recover anything already gone.

You can also tap Keep under an individual message to save just that one.

Audio messages are compressed hard for fast sending over a mobile connection. That is fine for a voice note and poor for anything you might want to keep, publish or edit.

For an idea you want to capture properly, use Voice Memos instead. It records at much better quality, keeps the file until you delete it, and exports something you can actually work with.

For anything intended for other people to listen to, a note, a lesson, an episode, record it as a recording rather than as a message. Hilite records in the browser on a phone and publishes from there, and we make it, so weigh that accordingly.
