You land, you find your gate or your hotel, and the first thing you look for is free Wi-Fi. It is one of the small pleasures of travelling: a signal that saves your data allowance and lets you check a boarding pass or a map without a second thought. Around that habit sits a whole industry telling you that a virtual private network, or VPN, is non-negotiable the moment you connect. The honest answer is more nuanced. A VPN can be genuinely useful abroad, but its value depends entirely on what you are doing and which network you are on, and it helps to know the difference before you pay for a subscription you may barely need.
What a VPN actually does, and what it does not
A VPN routes your internet traffic through an encrypted tunnel to a server run by the provider, then out to the wider web. That does two useful things. It hides your browsing from whoever else is on the same network, and it makes your connection appear to come from wherever that server sits, which can let you reach services that behave differently by country.
What a VPN does not do is make you anonymous or invulnerable. Your provider can see your traffic even if others cannot, you can still be tracked through logins and cookies, and it will not protect you from a dodgy download or a convincing scam email. It is a privacy and access tool, not a shield against every risk online.
Is public Wi-Fi really as dangerous as they say
The scary framing dates from an era when a lot of web traffic travelled in plain text. That has largely changed. The overwhelming majority of sites and apps now use HTTPS, which encrypts sensitive information such as passwords and card details between your device and the site, even on an open network. For everyday browsing, the real-world risk is considerably lower than the marketing around VPNs tends to suggest.
That said, open networks are not all equal. A hotel network with no password, a lookalike hotspot set up to fool travellers, or an old device you cannot vouch for all deserve more caution than a well-run cafe connection.
When it is genuinely worth switching on abroad
Rather than leaving a VPN running out of vague worry, switch it on when it does real work. The clearest cases are:
- You are on an open network with no password, or one you have no reason to trust.
- You are sending something genuinely sensitive, such as work documents or financial details.
- You want to reach home-country content, banking apps or streaming that misbehaves once you are abroad.
Connectivity itself matters here too. If you would rather avoid patchy hotel Wi-Fi altogether, a local data plan through a downloadable eSIM for travelling abroad gives you your own connection, and a VPN then sits neatly on top of it for the moments that call for one.
How to pick one you can actually trust
Because a VPN sees all your traffic, the provider you choose matters more than any single feature. This is exactly where free services deserve suspicion: running a network costs money, and if you are not paying, your data or your attention is often the product. A handful of dubious free apps have been caught logging activity or injecting adverts.
When comparing options, weigh up the things that reveal whether a provider takes your privacy seriously:
- A clear no-logs policy, ideally one that has been independently audited.
- A company base and reputation you can look up rather than a faceless app listing.
- Modern encryption and a kill switch that cuts traffic if the tunnel drops.
- A fair, transparent price, since a modest paid subscription is almost always safer than a free tunnel of unknown origin.
Treat a VPN as one sensible layer among several, alongside strong passwords, two-factor logins and a healthy scepticism about links. Used that way, it is a practical companion for a trip rather than a cure-all you need to leave running every waking hour.
