Hotel Wi-Fi, airport hotspots, blocked apps: here's why a VPN belongs on every packing list, and how it pairs perfectly with a travel eSIM.
Hotel Wi-Fi. Airport Wi-Fi. That "FreeBeachBarWIFI" you joined without thinking twice because you just wanted to send one photo. 🏖️
Holidays are exactly when we're most relaxed about our data - and exactly when we should be the most careful. The good news: a VPN takes about thirty seconds to switch on, and it quietly handles the boring security stuff while you get back to your cocktail.
Here's why we think a VPN belongs on every packing list, right next to your charger and your eSIM.
A VPN (Virtual Private Network) builds an encrypted tunnel between your phone or laptop and a server somewhere else in the world. Everything you send goes through that tunnel.
Two practical results:
1. Nobody on the local network can read your traffic. Not the person two tables over, not whoever runs the router. 2. Websites see the VPN server's location instead of yours. Handy when a service behaves differently depending on where you appear to be.
That's it. No magic, no hacking, no dark web. Just a private lane on a very public motorway.
Every time you join open Wi-Fi, you're trusting equipment you've never seen, configured by someone you'll never meet. Most of the time it's fine. But on shared networks it's genuinely possible for someone to set up a lookalike hotspot, capture what passes through, or push you to a fake login page.
Modern websites use HTTPS, which helps a lot. But not everything on your device speaks HTTPS all the time, and DNS requests - the list of everything you look up - often travel in the clear. A VPN wraps the lot.
Rule of thumb: if you didn't set the password yourself, treat the network as a public place. Turn the VPN on before you log into anything.
Two things people do on holiday that deserve protection:
Checking a bank app or paying for a tour with a card Opening work email "just for five minutes"
Both involve credentials you really don't want travelling naked across a café network. If you use a work laptop abroad, many IT policies actually require a VPN - worth checking before you leave rather than after.
You've paid for a streaming subscription at home, land abroad, open the app - and half your library has vanished. Your online banking suddenly wants five extra verification steps because you're logging in from an unfamiliar country. A news site you read daily shows a cookie wall you've never seen before.
None of that is a bug; it's location-based logic. With a VPN, you can connect through your home country and get the internet you're used to. (Do check the terms of individual services - rules vary, and we'd rather you know that up front.)
Some destinations block popular apps outright. In others, hotel or campus networks filter aggressively - VoIP calls fail, messaging apps won't connect, video won't load. A VPN routes around most local filtering, which is why so many travellers install one before flying to China, Turkey, the UAE or Russia.
Two honest caveats:
Set it up before you go. In countries with heavy restrictions, the VPN provider's own website and app store listing may be blocked once you arrive. Install and test at home. Check local law. VPN use is legal in most of the world, but a handful of countries regulate or restrict it. Ten minutes of reading beats an awkward surprise.
Your IP address is one of the simplest ways advertisers and data brokers tie your activity together. Hiding it doesn't make you invisible - cookies and logged-in accounts still know you - but it removes one of the easiest breadcrumbs. Some travellers also notice fewer wild price swings on booking sites when their location isn't broadcast on every search. Not a guarantee, just a nice side effect.
Here's the thing about public Wi-Fi: the best defence is not needing it.
With a travel eSIM you land with your own mobile data, on the local carrier network, without hunting for hotspots or paying roaming rates. Then you add a VPN on top for encryption and location control. Together they cover almost everything that can go wrong with connectivity abroad:
| Problem | eSIM | VPN | | --- | --- | --- | | Sky-high roaming bills | ✅ | – | | Untrusted public Wi-Fi | ✅ (skip it entirely) | ✅ (encrypts it) | | Blocked apps at your destination | – | ✅ | | Streaming library changes | – | ✅ | | Working securely from a café | ✅ | ✅ |
JamboSim handles the data side: pick a country or regional plan, scan the QR code, and you're online the moment you land. JamboVPN handles the privacy side. Use them together and your phone abroad behaves almost exactly like your phone at home.
1. Install and test your VPN at home - including a connection to a server in your own country. 2. Turn on auto-connect for unknown or unsecured Wi-Fi networks if your app supports it. 3. Install your eSIM before departure, while you still have a stable connection. 4. Update your apps and enable two-factor authentication on email and banking. 5. Note the local law on VPNs for your destination, and download offline maps as a backup.
A VPN isn't paranoia - it's the travel equivalent of locking your suitcase. It costs almost nothing, takes seconds to switch on, and it means the sketchy hotel Wi-Fi becomes somebody else's problem.
Pair it with a JamboSim eSIM so you're on your own data from the moment you land, and the only thing you'll need to worry about on holiday is whether the pool bar is still open. 🍹
