Hi Rian,
What do you mean by "it fails"? Do you mean you didn't received the text message with a verification code?
Also, since the signup issue is usually a temporary server interruption, could you try again later?
If the issue persists, feel free to post back and capture a screenshot of the error message for our reference.
Note: You can upload the screenshots by clicking Use rich formatting in the forum and then clicking the icon of Insert Image.
Thanks,
Frank
