Create an iMessage Profile
This is an exciting new feature available in iOS 13. You can create an iMessage profile that includes your first and last name, and a customizable profile picture for others to see while you’re chatting with them.
- Open Messages.
- Select the Settings button (the three dots in the top-right), and choose the Edit Name and Photo option.
- Enable Share Name and Photo so that your profile appears in conversations.
Don’t worry, you can adjust who exactly it appears to, limiting it to just friends or on a case-by-case basis.
