As soon as you sign up, a text will be sent to the phone number you signed up with. It will contain a verification link. Simply click the link and you will be taken to a verification page. This page will tell you if verification was successful. If successful, you can close the page and return to the previous page.

If verification was not successful, this usually means the link has expired or that the phone number was already verified.

You can check this by logging in to your dashboard and clicking on "Settings" from the menu. Under your phone number it will tell you the verified/unverified status. If unverified, you can click "resend" to receive a fresh verification link.
