Why Every Traveller Needs a VPN (and How to Use Mobile Data Smarter with an eSIM)

If you’ve ever used free WiFi at a hotel, airport, or café while travelling, you’ve probably put your data at risk — even if you didn’t realise it.

And if you’ve ever come home to an eye-watering phone bill or spent your holiday hunting for WiFi to check Google Maps, you know how frustrating staying connected can be.

Thankfully, two simple tools can make travelling both safer and easier: a VPN and an eSIM.

They’re not as complicated as they sound — and once you’ve tried them, you probably won’t want to travel without them again.

What Is a VPN and Why Do You Need One?

A VPN (Virtual Private Network) protects your personal information when you’re online. It creates a secure, encrypted connection between your device and the internet, even on public WiFi networks, which are often not secure.

Without a VPN, hackers and snoops can intercept your activity and potentially access sensitive information, such as passwords, banking details, or emails. With a VPN, your data is scrambled and shielded from prying eyes.

And it’s not just for overseas travel. Public WiFi in local airports, hotels, cafés, shopping centres and even on domestic flights can be just as risky. A VPN gives you peace of mind whether you’re in another country or just a few hours from home.

Using a VPN while travelling means you can:

• Check your bank account or pay bills online without worrying about security
• Access websites and streaming services as if you were still at home
• Avoid targeted ads and tracking based on your location

We recommend NordVPN because it’s reliable, easy to use, and works across phones, tablets, and laptops. Just install the app, tap to connect, and you’re protected.

What’s an eSIM and How Can It Help While Travelling?

Staying online while travelling used to mean expensive international roaming charges or fiddling with foreign SIM cards. An eSIM (embedded SIM) offers a more innovative, more straightforward solution.

An eSIM lets you download a mobile data plan directly to your phone before your trip. No plastic SIM cards, no visits to local phone shops, and no need to swap your current number.

With a travel eSIM like Saily, you can:

• Buy affordable data for your destination before you go or while you’re there
• Get online instantly, without relying on patchy public WiFi
• Keep your regular SIM active, so you don’t miss important calls or messages

It’s especially handy for maps, booking apps, ridesharing, and travel updates — the essentials that make a trip run smoothly.

Why Use Both?

• A VPN keeps your personal data private.
  An eSIM keeps you connected wherever you are.

Together, they give you more freedom and peace of mind, whether you’re exploring a new city or taking a weekend road trip.

Final Tip

Technology can feel overwhelming, but tools like VPNs and eSIMs are designed to make life easier, not harder. Once they’re set up, they work quietly in the background, keeping your information secure and your internet connection reliable.

If you’re travelling soon (even just locally), this is a great time to give them a go.
