Apple made it easy to answer phone calls on your Apple Watch, but what if it’s not a good time to talk? You can tap the red decline button to send the caller to voicemail. If that feels harsh or unhelpful, you can decline while simultaneously replying via text message. Scroll down on the incoming-call watch face to reveal the Send a Message button. Tap it to bring up controls for sending a message to the caller. Most useful are the buttons for sending canned messages, including “Sorry, I can’t talk right now,” “I’m on my way,” and “Can I call you later?” Scroll down to see all these messages, and tap the most appropriate one. Along with being able to leave voicemail, the caller will receive your message, assuming they’re using a phone that can receive text messages.
