Question

 How do I forward SMS/MMS text messages from my iPhone to all my Apple devices (Mac, iPad, or iPod Touch)?

Answer

Your iPhone has a built in feature that allows it to forward text messages (SMS/MMS messages) to all your other Apple devices.  When enabled, this allows you to both send and receive SMS/MMS messages on devices other than your iPhone.  For a guide on how to enable this feature, please visit Apple Support's website

 This is a useful feature if you are away from your iPhone but using your Mac, iPad, or iPod Touch.
