This phone number is already in use for another account
Common ProblemsI cannot add SMS protect, I receive the error "This phone number is already in use for another account"
A phone number can only be used for SMS protect in one Blizzard account at a time.
If you have more than one Blizzard account and you used your phone number to add SMS Protect to one of them, you must remove the number from the first account before you can add it to the second.
If you cannot detach the number from your other account, contact us.
