Messaging is intended for short messages and relatively instant communication. This is a middle ground between voice, and email. You can choose the messaging option that is best for you. My goal is to consolidate and keep things simple. With that in mind, you can send iMessage, SMS, and WhatsApp messages to my [Cellular] Number. Keep in mind that I might not be immediate in replies when I am not home, or if I’m in disposed of. This will include eating dinner, watching the news, or on the phone with a caller.
