Hi trudi7979,
I'm sorry to hear you are having message issues on your devices. From your description, it sounds like it may be a setup issue with the SMS function of Continuity under iOS 8. If so, you may want to verify the following settings:
- Your iPhone, iPad, and iPod touch need to use iOS 8.1, and your Mac needs to use OS X Yosemite.
- Sign in to iMessage on your iPhone, your other iOS devices, and your Mac using the same Apple ID.
- On your iPhone:
- Go to Settings > Messages > Send & Receive > You Can Be Reached By, and add a check to both your phone number and email address.
- Go to Messages > Text Message Forwarding, and enable the device(s) you would like to forward messages to.
- Your Mac, iPad, or iPod touch will display a code. Enter this code on your iPhone to verify the SMS feature.
