How do I sign up with my phone number, and what if the code does not arrive?
Signing up from the home page
You can also sign up from the home page: type your phone number in the "Phone number" field, tap "Get free trial lessons" and pick a time. If the number is new, the same "Sign Up" window opens.
How you know it worked
After "Confirm" you are already signed in to the new account. If you signed up while booking a trial lesson, the lesson is booked and appears on the "My Lessons" page.
