iPhone group texts work through the Messages app and work differently depending on whether you use iMessage or SMS
To send a group text on iPhone, open the Messages app, tap the pencil icon in the top left corner, then tap "New Message." Type the names or phone numbers of the people you want to include — you can add them one at a time or paste multiple numbers separated by commas. Type your message and hit send. The message goes to everyone at once, and replies come back to the group thread so everyone can see the conversation.
The experience changes based on what type of message you're sending. If everyone in the group has an iPhone and iMessage is turned on, the group text uses Apple's encrypted iMessage service and appears in a blue bubble. If even one person uses Android or has iMessage turned off, the group converts to SMS (standard text messaging) and appears in a green bubble. This matters for privacy: iMessage is encrypted end-to-end, while SMS is not.
Key Takeaways
- Open Messages, tap the pencil icon, type multiple names or numbers separated by commas, and send — everyone receives the same message in one thread.
- Blue bubbles mean iMessage (encrypted, iPhone-to-iPhone), and green bubbles mean SMS (unencrypted, works with any phone).
- You can mute notifications from a group text without leaving it, by swiping left on the conversation and tapping the bell icon.
- If you want to remove someone from an ongoing group text, you cannot do it directly in Messages — you have to start a new group without that person.
The difference between iMessage groups and SMS groups
When all members of your group use iMessage, the conversation stays encrypted and you get features like read receipts (small text showing who has read your message), typing indicators (the three dots showing someone is typing), and the ability to react to messages with emoji. You can also edit or unsend messages up to 15 minutes after sending. These features only work in iMessage.
The moment you add someone with an Android phone or someone whose iMessage is off, the entire group converts to SMS. You lose encryption, read receipts, and the ability to edit messages. SMS groups still work — everyone still gets the message and can reply — but the technical backbone is different. If you later remove that Android user and it's back to all iPhones, the group does not automatically switch back to iMessage. You have to start a new group to get those features again.
How to add or remove people from a group text
To add someone to an existing group text, open the conversation, tap the group name at the top, then tap "Add Contact." Find the person you want to add and tap their name. They will see the entire message history from that point forward, and everyone in the group will see a notification that they joined.
Removing someone is less straightforward. You cannot remove a single person from a group text in iOS — there is no "remove member" button. Your only option is to start a new group conversation without that person. This is a real limitation if you need to exclude someone mid-conversation. Some people work around this by creating a group in a third-party app like WhatsApp or Telegram instead, where removal is built in.
Muting notifications without leaving the group
If a group text becomes noisy and you do not want to see notifications but still want to stay in the conversation, you can mute it. Swipe left on the group conversation in your Messages list, tap the bell icon with a slash through it, and choose how long to mute — options are one hour, eight hours, one day, or one week. After that time, notifications turn back on automatically.
Muting silences notifications on your phone but does not hide the conversation or remove you from the group. Other members will not know you muted it. You can still read and reply to messages whenever you want; you just will not get the notification ping each time someone writes.
Privacy and security in group texts
If your group is using iMessage (blue bubbles), the messages are encrypted end-to-end, which means Apple cannot read them and neither can anyone intercepting the data in transit. If your group is using SMS (green bubbles), the messages are not encrypted. Your phone carrier can see the content, and so can anyone with access to your phone or your carrier account.
Group texts also create a record on your phone. If someone gets access to your device, they can read the entire conversation history. If privacy is a concern — for example, if you are discussing sensitive information with a group — consider using a dedicated messaging app like Signal or WhatsApp instead. Both allow you to set messages to disappear after a set time, and both encrypt group conversations end-to-end regardless of whether members use iPhone or Android.
What happens when someone leaves a group text
In iMessage groups, a member can leave by opening the conversation, tapping the group name, scrolling down, and tapping "Leave this Conversation." When they do, everyone in the group sees a notification that they left. The conversation continues for everyone else.
In SMS groups, there is no formal "leave" function. A person can stop replying, but they will still receive messages unless they block the group or delete the thread. Some carriers offer a way to opt out of group texts, but this varies by provider and is not a standard iPhone feature.
Troubleshooting common group text problems
If a group text is not sending, check that iMessage is turned on (Settings > Messages > iMessage toggle). If it is on and messages still will not send, try turning it off and back on. If the group keeps converting to SMS when you thought everyone had iMessage, ask the members to confirm their iMessage is on — sometimes it turns off automatically after a software update or if someone is low on storage.
If you are not seeing replies from one person in a group, they may have left the conversation or their phone may be blocking the group. Ask them directly whether they are receiving your messages. If read receipts are on but one person's never show, they may have turned off read receipts in their own settings, which is a per-person choice.
If a group text suddenly switches from blue to green, someone in the group either turned off iMessage, switched to Android, or their iMessage service is having an issue. The group will stay green until everyone with an iPhone has iMessage on again — and even then, you may need to start a new group to switch back.
Frequently Asked Questions
Can I see who has read my group text message?
Only in iMessage groups (blue bubbles). Tap the group name at the top of the conversation and you will see a list of members with "Delivered" or "Read" next to each name, plus the time they read it. In SMS groups (green bubbles), read receipts do not exist — you have no way to know if someone has read your message.
What is the maximum number of people I can add to a group text?
There is no hard limit built into iPhone Messages, but practical limits exist. Very large groups (50+ people) can become slow or unreliable, especially if some members are on SMS. For large groups, a dedicated app like Slack, Discord, or a group chat feature in WhatsApp usually works better.
If I delete a group text conversation, do other members still have it?
Yes. Deleting a conversation from your phone only removes it from your device. Everyone else in the group still has the full thread and can continue messaging. If you want to stop receiving messages from a group, you have to leave it (in iMessage) or mute it.
Why did my group text turn green when I added one person?
That person either has an Android phone, has iMessage turned off, or is using a phone number that is not registered with iMessage. Even one non-iMessage member causes the entire group to switch to SMS. Ask them to turn on iMessage in Settings > Messages if they have an iPhone, or accept that the group will stay unencrypted.
Can I schedule a group text to send later?
Not natively in the iPhone Messages app. You would need to use a third-party app or set a reminder to send the message at a specific time. Some messaging apps like WhatsApp or Telegram have scheduled message features, but standard iPhone Messages does not.
