Free Wi-Fi is now often seen as an essential of travelling found in airports, hotels, cafés, and co-working spaces around the world. It’s convenient and acts as a comfort, but public Wi-Fi also comes with hidden risks so a little awareness (and the right tools) can make a big difference.
The risks of public Wi-Fi
Public networks are often unsecured or poorly secured, meaning other users on the same network may be able to intercept data. This can include login details, emails, messages, or personal information. In some cases, fake networks are deliberately set up to look legitimate, particularly in airports and tourist areas and is equally as risky in developed and developing parts of the world.
This doesn’t mean you should never use public Wi-Fi, but you should be careful about how you use it.
Why using a VPN is a good idea
A VPN, or Virtual Private Network to give it its full name, encrypts your internet connection, making it far harder for anyone else on the network to see what you’re doing. It also masks your IP address, adding an extra layer of privacy.
Benefits of using a VPN while travelling include:
- Protecting your data on public Wi-Fi
- Reducing the risk of hacking or data interception
- Accessing services that may be blocked or restricted abroad
- Adding privacy when using hotel, café, or airport networks

When not to use public Wi-Fi
Even with a VPN, there are situations where it’s best to avoid public Wi-Fi altogether.
Try not to use public networks for:
- Online banking or financial apps
- Entering card details or making large purchases
- Accessing sensitive work systems
- Logging into important accounts if you can avoid it
If you must do these things, use mobile data or your own secure connection instead.
Why mobile data is often safer
Using your own mobile data—via roaming, a local SIM, or an eSIM—is generally much more secure than public Wi-Fi. It’s also often faster and more reliable, especially in busy areas.
If you’re not familiar with eSIMs, they’re one of the easiest ways to stay connected abroad without relying on public networks. We cover this in detail in our Mobile Data and Roaming guide, including when they make sense and how to choose the right one.
Practical Wi-Fi safety tips
- Turn off auto-connect to public Wi-Fi networks
- Avoid networks that don’t require a password
- Check the network name with staff before connecting
- Keep your devices and apps updated
- Log out of accounts when you’re finished
The bottom line
Public Wi-Fi is useful, but it shouldn’t be trusted by default. Use a VPN, avoid sensitive tasks on open networks, and lean on mobile data or eSIMs when security matters. Travelling connected is easy—travelling connected safely just takes a bit of planning.
