Threads can also include group conversations with multiple people, and you can add or remove participants as needed. Additionally, you can customize thread settings to enable do not disturb mode or change the thread name to help you easily locate specific threads when needed.
In summary, a thread on an iPhone is a conversation that is grouped together in the Messages app. It includes all communication history with a specific contact, making it easy to view and track your conversations.
