Each phone number is tied to exactly one account for security reasons, so it can’t be registered more than once.
A few reasons this may happen:
You created an account previously and may have forgotten
You started registration but didn’t finish.
Someone else registered with your number (unlikely, since phone numbers are verified)
Try logging in at the portal using your phone number. Instead of signing up.
