How can I be alerted by SMS in the event of a disruption on my line?

This question has not been updated and is likely to be outdated. To see the answer to your question, go here.

On a route that is used regularly, we advise you to subscribe to traffic alerts to receive a notification on your smartphone as soon as a disruption is known on the route. The subscription function can be accessed from the "Line" screen in the "Timetables" or "Traffic Info" section, by clicking on the button at the top right or from the stage of a route map by clicking on the button "more actions on this stage" ("...").
The subscription function from the app does not require you to create an account beforehand.
