Do You Need a VPN When Travelling? What It Does — and What It Doesn’t
Last reviewed: 20 August 2026
Quick answer: a VPN can be useful when travelling because it creates an encrypted connection between your device and the VPN service. That can reduce what the local Wi-Fi operator or another party on the local network can see about your traffic. It does not create internet access, guarantee anonymity, make every website trustworthy or protect you from giving passwords to a fake login page.
What a VPN actually changes
Without a VPN, your device connects through the hotel, airport, café or mobile network to the services you use. Most modern websites already use HTTPS, which encrypts the content between your browser and that website. A VPN adds another encrypted tunnel between your device and the VPN provider.
That changes who can observe parts of your connection. The local network sees that you are communicating with a VPN endpoint rather than directly seeing every internet destination in the same way. The VPN provider, however, becomes part of the trust chain. That is why choosing a reputable provider matters more than choosing the loudest advert.
What a VPN does not do
- It cannot give you internet when Wi-Fi, mobile data and every other connection are down.
- It cannot make a malicious website safe.
- It cannot stop you entering credentials into a phishing page.
- It cannot guarantee that a hotel, bank or streaming service will accept your connection.
- It cannot make you completely anonymous online.
Public Wi-Fi is not automatically dangerous
Modern encrypted web and app traffic is much safer than the open-web era that created many of the familiar “never use airport Wi-Fi” warnings. That does not mean every hotspot deserves trust. Fake access points, captive portals, poor router configuration and unnecessary file-sharing can still create risk.
A sensible travel setup combines updated devices, HTTPS, strong account authentication and careful hotspot selection. A VPN can be another layer rather than the entire security plan.
When a VPN is most useful
A VPN makes the most sense when you routinely use networks you do not control, need secure access to a work or home network, or want one consistent encrypted tunnel across hotels, stations and cafés.
For a business-managed device, follow the organisation’s security policy rather than installing a consumer VPN independently.
Captive portals can be awkward
Some hotel and airport Wi-Fi networks require you to open a sign-in page before normal internet traffic works. A VPN configured to block all traffic until its tunnel is established can interfere with that process. You may have to authenticate to the Wi-Fi portal first and then enable the VPN.
The UK’s National Cyber Security Centre notes the trade-off between forcing all traffic through a VPN and the compatibility problems this can create with captive portals.
Travel checklist
- Update the phone or laptop before travelling.
- Use a password manager and multi-factor authentication where available.
- Disable automatic joining of unknown Wi-Fi networks.
- Confirm the real network name with the venue when unsure.
- Use mobile data instead of public Wi-Fi where that is simpler.
- If using a VPN, install and test it before the journey.
- Keep enough battery power to maintain the connection.
Bottom line
A VPN is a useful privacy and security layer, particularly for regular travellers, but it is not an emergency communications device. It protects a connection you already have. For resilience when a connection disappears, think instead about mobile-data backup, a second SIM, offline information and — for genuinely remote use — satellite communications.
