To cancel your "Deutschlandticket" (the 49-euro monthly transport pass) in 2026, you must follow the strict "10th of the month" rule. Because the ticket is sold as a recurring subscription, you must submit your cancellation request by the 10th day of the current month for it to be terminated by the end of that same month. For example, to stop the ticket for May, you must cancel by April 10th. The process is handled through the specific app or portal where you purchased it—most commonly the DB Navigator app, the HVV app, or your local transport provider's website. Within the DB Navigator app, you navigate to the "Tickets" section, select your active subscription, and use the "Cancel Subscription" button. In 2026, some providers also allow cancellation via their web-based "Aboportal" (subscription portal). If you miss the 10th-day deadline, the subscription will automatically renew for one more month, and the 49-euro fee will be deducted from your account.
