What is how to schedule a text on iphone?

Unfortunately, iPhones do not have a built-in feature to directly schedule text messages through the native Messages app. You can't officially schedule a text through Apple's native Messages app.

Here are some alternative ways to achieve similar results:

• Using Shortcuts App: You can create a custom automation using the Shortcuts App. This is the closest thing to a native solution. You'll need to create a personal automation that runs at a specific time, then add actions to send a text message to a specific contact.
• Third-Party Apps: There are some third-party apps available on the App Store that claim to schedule text messages. Be cautious when using these apps, as you'll need to grant them access to your contacts and messages. Always research the app's privacy policy and reviews before using it.
• Reminders App (Workaround): You can set a Reminder with a specific time and include the text you want to send. When the reminder goes off, you can copy the text and paste it into a new message. This doesn't automate the sending, but it reminds you to send the message at the desired time.
• Using Email to SMS Gateways (Advanced): Some mobile carriers offer email to SMS gateways. You can schedule an email through your email app to the carrier's specific email address that will then send the message as a text. This method can be unreliable, and you'll need to research your carrier's specific gateway address.
