What a group chat is and how to create one
A group chat is a conversation thread where you can message multiple people at once instead of sending the same message to each person separately. On iPhone, you create a group chat by opening the Messages app, starting a new message, and adding more than one contact before you type anything. The group chat then stays in your message list so everyone in it can see all replies in one place.
The simplest way is to add people before you send your first message. Once the group exists, anyone in it can add new people or remove themselves, depending on the settings you choose. Group chats on iPhone work over iMessage (which requires internet or cellular data) or standard text messaging, depending on who is in the group and what their phone can do.
Key Takeaways
- Open Messages, tap the pencil icon to start a new message, then type or select multiple contacts before sending your first message.
- If everyone in the group has an iPhone or uses iMessage, the chat will be blue and include features like reactions and read receipts.
- If even one person uses Android or a non-iMessage phone, the chat turns green and works as a standard group text message.
- You can name the group, change the photo, and control whether people can add others or leave without permission.
- Group chats stay in your Messages app permanently until you delete the entire conversation thread.
Opening Messages and starting a new conversation
Tap the Messages app on your home screen — it is the green icon with a white speech bubble. Once it opens, look at the top right corner and tap the pencil and paper icon (or on newer iPhones, a pencil icon). This opens a blank message screen where you can add people.
At the top where it says "To:", tap that field and start typing the first person's name. As you type, your contacts will appear below. Tap the name to add them. Repeat this for every person you want in the group. You can add as many people as you want, but group chats work best with between 3 and 15 people — larger groups can become hard to follow.
Adding multiple people before sending
The key to creating a group chat is adding all the people you want before you type your first message. After you type each name in the "To:" field, that person's name appears as a small bubble or pill below the field. You can see all the people you have added at a glance.
If you add someone by mistake, tap the small X on their name bubble to remove them. Once you have everyone you want, scroll down to the message box (where it says "iMessage" or "Text Message") and type your message. When you hit send, the group chat is created and everyone receives the message at the same time.
Blue chats versus green chats and what the difference means
If all the people in your group have iPhones and use iMessage, the chat bubble will be blue. Blue group chats include extra features: you can react to messages with emoji, see when people are typing, and know when they have read your message. These chats use data or WiFi, not your text message plan.
If even one person in the group uses Android, a basic phone, or does not have iMessage turned on, the chat turns green and becomes a standard group text message. Green chats do not show typing indicators or read receipts, and reactions do not work the same way. Green chats use your text message plan instead of data. You cannot change a green chat to blue — it depends entirely on who is in the group.
Naming the group and adding a photo
Once the group chat exists, you can give it a name instead of seeing a list of everyone's names at the top. Open the group chat, then tap the group name or the circle with initials at the very top of the screen. This opens the group details page.
Tap "Enter a Group Name" and type whatever you want — "Weekend Plans", "Work Team", "Book Club", anything that helps you remember what the chat is for. Below that, you can tap the circle to add a photo. You can take a new photo, choose one from your library, or use an emoji. Tap "Done" when you finish. Everyone in the group will see the name and photo you chose.
Controlling who can add people and change settings
On iPhone, you can control whether people in the group can add new members or change the group name and photo. Open the group chat, tap the group name at the top, then scroll down and look for "Group Details" or similar options (the exact wording changes by iOS version).
You will see toggles for "Allow Notifications" and sometimes "Allow Members to Add Members" or "Allow Members to Leave". If you turn off "Allow Members to Add Members", only you can add new people. If you turn off the option to leave, people cannot remove themselves from the chat. These settings only work in blue iMessage group chats — green text message groups do not have these controls.
Leaving a group chat or removing someone
To leave a group chat, open it, tap the group name at the top, scroll down, and tap "Leave This Conversation". You will be removed and will no longer receive messages. Everyone else in the group will see a notification that you left.
To remove someone else from the group, open the group chat, tap the group name at the top, find the person's name in the list, and tap "Remove" next to their name. This only works if you created the group or if the group settings allow members to remove each other. In green text message groups, you cannot remove people — they can only leave on their own.
Frequently Asked Questions
Can I add someone to a group chat after it is already created?
Yes. Open the group chat, tap the group name at the top, tap "Add Contact", and select the person you want to add. They will see all future messages but not the old conversation history, unless your group settings allow them to see it.
Why did my blue group chat turn green?
Someone in the group either turned off iMessage, switched to Android, or their iMessage account had a problem. Once one person is not using iMessage, the entire chat becomes a green text message group. It will turn blue again only if that person fixes their iMessage or leaves the group.
What happens if I mute a group chat?
You will still receive messages, but you will not get notifications or sounds. Open the group chat, swipe left on it (or long-press it), tap "Mute", and choose how long — usually "1 hour", "8 hours", or "1 day". You can unmute anytime by doing the same thing and tapping "Unmute".
Can I see old messages in a group chat I just joined?
No, not by default. When you are added to a group chat, you see only messages sent after you joined. Some groups may have settings that let new members see history, but this is not standard.
Is there a limit to how many people can be in a group chat?
Technically no, but group chats with more than 50 people often become slow or unreliable. Most people keep group chats between 3 and 20 people for that reason.
