Do you need a VPN when travelling abroad?

Quick answer: A VPN is useful on public Wi-Fi and for keeping some services working, but it is not essential for every trip. It encrypts your traffic between your device and the VPN server. It does not stop phishing, fix a weak password or make you anonymous.

What a VPN actually does

A VPN (virtual private network) wraps your internet traffic in an encrypted tunnel to a server run by the VPN company. Anyone on the same hotel or airport Wi-Fi network cannot read what passes through that tunnel. Websites also see the VPN server's location, not yours.

When it is worth having

You use public Wi-Fi a lot in hotels, airports, cafes and trains, especially for email, work or anything with a login.
You need to reach UK services that behave differently abroad. See using UK banking apps abroad and watching UK streaming abroad.
You work remotely and want an extra layer on untrusted networks.

When it is not the answer

If you only use mobile data from an eSIM or SIM, your traffic is already not on a shared Wi-Fi network. See eSIM vs roaming vs local SIM.
A VPN does not protect you from a fake login page, a malicious attachment or a reused password. Use two-factor authentication and a password manager.
Most websites now use HTTPS, which already encrypts the content of your connection. A VPN adds another layer rather than being the only protection.

Check the rules where you are going

VPN use is restricted in some countries. Read countries where VPNs are restricted and the GOV.UK foreign travel advice before you go.

If you decide to buy one, see NordVPN vs Surfshark for travellers and avoid free VPNs.

Frequently asked questions

Is a VPN legal abroad?

In most countries yes, but a few restrict or ban them. Check the destination page on GOV.UK foreign travel advice and the local rules before you travel.

Will a VPN make me anonymous?

No. It hides your traffic from the local network and changes the location websites see, but the VPN company can still see its own connection logs, and logging into accounts still identifies you.

Do I need a VPN if I use my phone's data?

Usually less so. Mobile data is not a shared Wi-Fi network, so the main risk a VPN addresses is smaller. It can still help you reach certain services.
