When the actual circumstances differ from what you expected, the most important thing is not to argue with other passengers, but to find the person in charge as quickly as possible. When travelling abroad, your mobile phone serves as a ticket, a map, a means of accessing your bank account and a contact list all in one. Therefore, you should check all your settings at home and back up any critical data using a secure offline method.
What to do before your trip
Update your apps, set up a screen lock, enable Find My Device, and keep your backup codes separate from your phone. Check that the necessary features work without Wi-Fi. Do not use public networks for high-risk operations if you can postpone them until you have a secure connection.

Step-by-step guide
Show your ticket or confirmation to a member of staff, briefly explain the issue and wait for a decision. Do not occupy someone else’s seat or move your luggage without permission.
If the decision is temporary, clarify the next step and make a note of who gave you the information; this is particularly useful when changing trains.
