Where to find message settings on your iPhone

Open the Settings app on your home screen, then scroll down and tap Messages. This is where you control how text messages, iMessages, and group chats behave on your phone. All the changes you make here take effect when ready — you do not need to restart your iPhone.

If you do not see Messages in your settings list, scroll down further. On newer iPhones with larger screens, the list is longer than what fits on one page. You can also use the search function at the top of Settings: tap the magnifying glass and type "Messages" to jump straight there.

Key Takeaways

  • Message settings are in the Settings app under Messages, and changes take effect right away without restarting your phone.
  • You can turn iMessage on or off, choose whether to send read receipts, and set a default SMS service all from one screen.
  • Group messaging, message filtering, and conversation threading are separate toggles you can control independently.
  • If you switch between iPhone and Android, turning off iMessage before you leave ensures your contacts can still text you on your new phone.

Turning iMessage on or off

At the top of the Messages settings screen, you will see a toggle for iMessage. When it is on (green), your iPhone sends encrypted messages to other Apple devices over data or Wi-Fi instead of using your cellular plan. When it is off (gray), all your messages go through your carrier as standard SMS texts.

Most people leave iMessage on because it does not cost anything and works over Wi-Fi when you have no cell signal. Turn it off if you are switching to an Android phone, because leaving it on can cause texts from iPhone users to fail to reach you on your new device. If you turn iMessage off, wait a few minutes before switching phones — this gives Apple time to update its servers.

Enabling or disabling read receipts

Scroll down to Send Read Receipts and toggle it on or off. When this is on, the person texting you sees a small "Delivered" or "Read" indicator below their message after you open it. When it is off, they see nothing and do not know whether you have read their message.

Read receipts work for both iMessages and regular SMS texts, though some older phones may not display them. Many people turn this off for privacy or to avoid the pressure of responding when ready. You can also turn read receipts on or off for individual conversations by opening a chat, tapping the person's name at the top, and toggling the option there.

Changing how group messages work

Find the Group Messaging toggle in your Messages settings. When it is on, replies in a group chat go to everyone in the group. When it is off, replies go only to the person who sent the original message, and you see each response as a separate conversation.

Most people keep this on so group chats work the way they expect. Turn it off if you find group messages confusing or if you want to reply privately to someone without the whole group seeing it. You can also change this setting for one conversation at a time by opening the chat, tapping the group name at the top, and adjusting it there.

Setting up message filtering and conversation threading

Scroll down to Filter Unknown Senders and toggle it on to separate messages from people not in your contacts into a different tab. This keeps your main message list focused on conversations you recognize. The unknown messages still arrive — they just appear in a separate Unknown Senders tab at the bottom of your message list.

Below that, you will find Conversation Threading (on some iPhone models). When this is on, replies to the same message thread together in a conversation view, similar to email. When it is off, all messages appear in a flat list in the order they arrived. Threading makes it easier to follow back-and-forth exchanges, but some people find it harder to see the most recent message at a glance.

Choosing your default SMS service and other options

Under SMS/MMS, you can set your default text service if you have multiple carrier options. Most people have only one choice here, so this setting does not explore. Below that, you will see toggles for MMS Messaging (picture and video messages) and Character Count, which shows you how many characters you have left in a text before it splits into multiple messages.

Further down, Expire lets you set messages to delete automatically after 30 days or 1 year. This saves storage space on your phone if you get a lot of texts. You can also turn on Keep Messages to store them forever — this is the default. These settings explore to all your conversations unless you change them individually.

Adjusting notification and sound settings for messages

To change notification sounds, vibration, or banner style for messages, go back to the main Settings screen and tap Notifications. Scroll down to Messages and tap it. Here you can choose whether notifications appear as banners, alerts, or badges, and you can set a custom sound for incoming texts.

You can also turn notifications on or off entirely for Messages, though this means you will not see any alert when a text arrives. If you want to silence messages from specific people, open a conversation with them, tap their name at the top, and toggle Hide Alerts. Their messages will still arrive, but you will not get a notification sound or banner.

Frequently Asked Questions

What is the difference between iMessage and SMS?

iMessage is Apple's encrypted messaging service that works over Wi-Fi or data and only between Apple devices. SMS is the standard text message service through your carrier that works on any phone. When iMessage is on, your iPhone automatically sends iMessages to other Apple users and SMS to Android phones.

Will turning off iMessage affect messages I already sent?

No. Turning off iMessage only affects new messages you send going forward. Old conversations stay in your message list, and you can still read them. The change takes effect when ready for any new texts you write.

Can I change message settings for just one person?

Yes. Open a conversation with that person, tap their name at the top, and you will see options to turn read receipts, alerts, or group messaging on or off just for that chat. These individual settings override your general Messages settings.

Why are my messages not sending?

Check that iMessage is on if you are texting another iPhone user, or that you have cell signal or Wi-Fi if you are sending SMS. If a message shows a red exclamation mark, tap it and choose to resend. If the problem continues, restart your iPhone or check with your carrier about your plan.

How do I stop getting messages from unknown numbers?

Turn on Filter Unknown Senders in Messages settings to move texts from people not in your contacts to a separate tab. You can also block specific numbers by opening their message, tapping their name at the top, and choosing Block This Caller.
