Please note:

The use of Facebook messenger is currently not supported.


This is how the signing up works:

1) Select the messenger service thats supposed to inform you (Notify or Telegram).

2) Save the mobile phone number that is now displayed to you in your smartphone, for example under "Timetable information service".

Important: If you do not create this contact, our service will unfortunately not be able to reach you.

3)  Now send a chat message (not an SMS!) to this phone number with the
    request "START".

Now your access is activated. After a short time you will receive a welcome message.

If there are still questions, please contact us here.
