What Is iMessage and Why It Matters in 2025

iMessage is Apple’s built-in instant messaging service that lets users send texts, photos, videos, documents, and voice notes over the internet—bypassing traditional SMS charges. You can use it between iPhones, iPads, Macs, and Apple Watches.

Unlike regular SMS, iMessage uses end-to-end encryption for privacy and delivers messages via Wi-Fi or mobile data. In 2025, it has evolved with features like improved group chat controls, message editing, AI-powered suggestions, and iCloud message sync for smoother transitions across devices. (Apple Support)
