Packing light is one thing, but travelling smart online is another matter entirely. From spotty hostel Wi-Fi to roaming charges that quietly rack up in the background, the digital side of a trip abroad deserves as much planning as the itinerary itself, and a few simple habits can save you a serious headache down the line.
Public Wi-Fi: Handy but Risky (and the QR Code Trap)
Free Wi-Fi at airports, hostels and cafés feels like a travel perk, but open networks are a playground for cybercriminals. Without encryption, anything you send, like login credentials, payment details, and personal data, can potentially be intercepted by anyone on the same connection. Rogue hotspots, which mimic legitimate network names to lure users, are a particular hazard. If public Wi-Fi is your only option, routing your traffic through a remote access VPN encrypts your connection and makes it harder for anyone to snoop on what you’re doing.
It’s also worth watching out for QR code scams while you travel, which is a threat that’s moved well beyond the digital realm. According to Saga Insurances, nearly 800 reports of QR code fraud were made in the UK between April 2024 and April 2025, with victims losing close to £3.5 million. Car parks and transport hubs are common targets, where fake codes are placed over legitimate payment points to steal financial information.
Passwords, 2FA and Keeping Accounts Locked Down
The fundamentals of account security matter even more when you’re away from home. Using unique passwords for every account removes the domino effect of a single breach, and a password manager handles the heavy lifting of generating and storing complex credentials automatically.
As Which? explains, two-factor authentication gives another crucial layer of verification, meaning that even if your password has been discovered, a hacker won’t be able to get into your account without having access to your second device. Setting this up before you travel is particularly important for accounts like hotel loyalty programmes and airline profiles, which are common phishing targets and easy to overlook until something goes wrong.
Roaming Abroad Without Bill Shock (and Staying Secure)
Post-Brexit, most UK mobile networks have reintroduced roaming charges across Europe, so a quick check of your provider’s rates before departure is time well spent. Besides the financial side, your phone’s mobile data connection is generally a safer option than unknown public Wi-Fi when you need to access banking apps or booking platforms on the go. Tethering a laptop to your phone instead of connecting to a hotel network takes seconds and reduces your exposure to network-level threats.
Travelling with Devices: Simple Set-Ups That Actually Help
A few minutes of preparation before you fly can protect all your essential gear and prevent a great deal of grief later. Update your devices and apps before departure so any known security vulnerabilities are patched. Set a PIN or biometric lock on every device, and turn off automatic connection to open Wi-Fi networks in your settings, as your phone should only join networks you explicitly choose.
Avoid using public USB charging points, sometimes called “juice jacking” stations, as these can be used to sneakily transfer malware onto devices. A portable power bank is a cheap and practical alternative that keeps you charged without the risk.
A little preparation goes a long way when it comes to staying safe online abroad. Sorting your security basics before you travel means you can focus on the trip itself instead of firefighting problems from the other side of the world.
