Please I need a Magic Jack Account

Hello,

Please I want to sign up magic jack or create an account on magic jack on my iphone but I can't see the sign up icon, I have tried everything I can to create the account on my own effort but still it's not working, what I can only see is log in as an existing user and nothing else, please I need assistance on how to sign up as a new member because I
have never used it before on my iphone thank you.
