Public WiFi at airports and hotels: risks and why eSIM is safer
Almost every airport, hotel or cafe today offers free WiFi. It's convenient, but that convenience comes with risks many travelers don't notice until there's a problem.
In this article we explain the most common risks of public networks and why your own eSIM connection offers more peace of mind on the road.

Why public networks are riskier
Public WiFi is by definition open - a large number of unknown devices connect to the same network at once. That opens room for various forms of data interception, especially if the network lacks strong encryption or if a fake network is set up to look official.
- Fake networks with names similar to the official one (e.g. 'Airport_Free_WiFi')
- Interception of unencrypted traffic on open networks
- A shared network with an unknown number of other users at once
- Easier tracking and profiling of user behavior on the network
What's most sensitive on public WiFi
Online banking, card payments, logging into email or work systems are the activities with the highest risk. On a public network, you never really know who else is 'in the room' with you.
Why eSIM is the safer option
When you use mobile data through an eSIM, your connection goes directly through the mobile operator's network rather than through a shared public network that anyone can join. That alone reduces exposure to the kind of interception risk common on open WiFi.
On top of that, an eSIM gives you a stable connection without needing to hunt for a WiFi password at every location or wonder whether the network you're joining is really official.
When WiFi still makes sense
- For large downloads or streaming, to save mobile data
- At the hotel, where the network is usually more private and known
- For less sensitive activities, like reading news or browsing
- Always combined with a VPN if you're doing something more sensitive
Practical travel advice
The best combination is using your eSIM as the reliable, primary connection for anything sensitive, and saving public WiFi for lighter activities or when you want to save GBs. That way you get both security and flexibility.
Frequently asked questions
Is every public WiFi dangerous?
Not every one, but risk exists on any open network because you can't verify who else is on it.
Do I need a VPN alongside an eSIM?
It's not required, but a VPN adds an extra layer of protection for sensitive activities anywhere.
How do I spot a fake WiFi network?
Confirm the network name with staff on site, fake networks often have a similar but not identical name.
Does eSIM work right after landing?
Yes, as soon as you enable the eSIM line and data roaming, the connection is active with no WiFi password needed.
