This guide provides a comprehensive overview of how to update your iPhone in March 2026, covering both wireless and computer-based methods.

2. Connect to Wi-Fi: Ensure your iPhone is connected to a reliable Wi-Fi network.
3. Download and Install: If an update is available, tap Download and Install. You may be prompted to enter your passcode.
