You can receive text messages as well as attachments, including images, video, and audio files up to 8MB in size. I checked other contacts, and all of them have a phone number look at this website in the Text Message field in Messages, but a few have two Text Message fields, one with a phone number and one with an email address. This is the first time I have seen Messages send via email. Does anyone know of a fix? When you have a long story to tell but no time for a phone call, try audio messages. They can be a lifesaver if your connection is bad, too. Tap or click for steps to send audio messages on iPhone and Android. When it comes to sending a scheduled text message, there aren’t any free third-party workarounds that are reliable and secure. So generally, the best way to create a scheduled text is to set reminders for yourself to send the text later.
