New group message appears in old group chat

Which Group message? Group SMS or Group iMessage:

Types of group text messages

The Messages app chooses the type of message to send automatically based on your settings, network connection and network provider plan. For example:

• If all of the recipients are using Apple devices and iMessage is turned on, the group message will be sent as an iMessage.
• If any of the recipients aren’t using iMessage, the message will be sent as an MMS or SMS. In iOS 18 or iPadOS 18, you can also send RCS messages. Find out the difference between iMessage, RCS and SMS/MMS

Name a group conversation

You can name a group chat and choose an icon* to represent the conversation. Everyone who has turned on iMessage sees the new name and icon.

1. Go to the Messages app  on your iPhone.
2. Tap the group icon at the top of the conversation.
3. Tap Edit, tap Edit Name & Photo, then choose an option.

Group SMS

These messages also appear in green text bubbles and go through your provider. Group SMS messages don’t support multimedia attachments, such as photos or videos.

All responses in a group SMS are sent as individual text messages, and the recipients can’t see the other responses from the group.
