You might experience that when you answer a group message, you receive the same message yourself. This is because the Caller ID is set to Network default in the Xperia™ XZ Premium. You can change the Caller ID in the Call Settings menu.
To set Caller ID
- From your Home screen, tap the Application screen icon.
- Find and tap Settings > Call > Additional settings > Caller ID.
- Select Show number.
