Hi tctheissen,
Thanks for contacting Apple Support Communities!
We understand that you're unable to activate iMessage and FaceTime on your iPhone with your Apple ID, correct?
In order to use Messages with your Apple ID, you will need to be signed in with your Apple ID on your iPhone. You can go to Settings and "Sign in to your iPhone" as outlined here: Sign in with your Apple ID
"Sign in on your iPhone, iPad, or iPod touch
- Open the Settings app.
- Tap Sign in to your [device].
- Enter your Apple ID and password.
- If prompted, enter the six-digit verification code sent to your trusted device or phone number and complete sign in.
If you're already signed in to iCloud on the iPhone paired with your Apple Watch, you will automatically be signed in to that Apple ID. Learn more about how to set up and sign in to your Apple Watch.
Once you've signed in with your Apple ID, you can enable Messages in iCloud so that you can use Messages on both your iPhone and Mac: Set up iCloud for Messages on all your devices
"Set up iCloud for Messages on all your devices
You can use iCloud with Messages on your iPhone, iPad, iPod touch, and Mac. For an overview of what you can do with iCloud, see Keep your messages up to date with iCloud.
Note: Make sure you’re signed in with the same Apple ID on each device. If you have devices where you’re not signed in with your Apple ID or that have Messages for iCloud turned off, your messages won’t be kept up to date on those devices."
We hope this helps.
Cheers!
