This question already has an answer here:
When I send message on iMessage, it’s sent from my e-mail, which I am logged in iCloud with i.e. my Apple ID, not my phone number. In Settings → Messages → Send and Receive(?), is not my number, just my Apple ID e-mail.
Screenshot from Send and Receive:

What I have tried:
Disabling iMessages & FaceTime on both devices(iPhone and iPad), then restart and then enabling it again.
Logging out from AppleID in Settings → Messages → Send and Receive(?).
Adding my phone number in Settings → AppleID → Name, Phone Numbers, e-mail.
Neither of these worked!
