ans: There is a major difference between a “User” and a “Contact”.
User*: A person who can access the MyOperator account using his/her own registered phone number is a User(Add a new user)
Contact: A phone number that is added by a User to his MyOPerator account, updating his name and email address is a contact. Just like you save a phone number with a name in your cell phone! (Add a new contact)
*Note: All users can be in the contact list but not necessarily all those who are in the contact list, is a user.
