Since I need to use more than one email address, I wonder if there is any chance to create more than one free account at zoho. I tried to log out from zoho and go to zoho.com/mail/ in order to create a new account. However, when I was asked to enter my mobile number I entered my only mobile number, and zoho warned me that 'An account already exists for this mobile number', inviting me to log in with the existing account. 

I would appreciate any help on this issue.
