If you have not received the confirmation email after registration, please check your spam folder first. In most cases, you will find the email there. If you encounter any issues with receiving the SMS please do as follows: try to restart your phone, wait 15 seconds, and then try again. Also check if you have allowed and set to receive calls and messages, or A2P messages, from applications.
If you still have not received the letter or SMS, please contact our customer support via email firstname.lastname@example.org.
