On a multi-leg journey, each ticket should be considered separately, and you should allow a realistic amount of time between them for transfers and baggage handling. When travelling internationally, your mobile phone serves as a ticket, a map, a means of accessing your bank account and a contact list all in one. You should therefore 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 functions work without Wi-Fi. Do not use public networks for high-risk operations if you can postpone them until you have a secure connection.
- Your own adapter
- USB port
- Cable for power only
- device control
Step-by-step plan
Map out a simple route from arrival to your next connection. Include the walk between platforms, the toilet, baggage collection and any potential queues, rather than just the difference in timetables.
Prepare an alternative in case of a delay: the next flight, a safe place to wait and the contact details of the seller of the second ticket.

Questions and answers
Bringing your own adapter: what should you do?
Use your own adapter and a working cable; it’s best to treat unknown USB ports solely as a power source.
USB port: how do I check it?
A cable without data transfer reduces the risk of accidentally connecting to someone else’s device.
Power-only cable: when should you use it?
Do not leave your phone unattended near a power socket on a bus, in a café or at a station.
Device control: where to check?
Charge your power bank in advance and carry it in accordance with the specific carrier’s regulations.
