Free Wi-Fi is one of the small pleasures of travel. It is also a network you share with strangers, run by people you do not know. A few simple habits make using it far safer.
Why public Wi-Fi carries extra risk
On a public network, other people are connected to the same system as you. Fake hotspots can copy the name of a real one, and poorly set up networks can expose devices to each other. Most websites now use encrypted connections, which helps a lot, but it does not protect you from every trick.
Tips for safer public Wi-Fi
- Confirm the network name. Ask staff for the exact Wi-Fi name before you connect, because look-alike names are a common trap.
- Keep sensitive tasks for a trusted connection. Avoid banking, payments and password changes on public Wi-Fi.
- Look for HTTPS. Check for the padlock in your browser, and be wary of any page that asks you to download something to get online.
- Use a reputable VPN. A VPN encrypts your traffic between your device and the VPN provider, which helps on networks you do not trust.
- Turn off auto-join. Stop your phone from joining open networks automatically, and forget a network once you leave.
- Limit sharing. Set AirDrop or similar nearby sharing to contacts only, or turn it off, and switch off file sharing on laptops.
- Keep everything updated. Software updates fix known security problems, so install them before you travel.
- Use two-factor authentication. An authenticator app adds a second barrier if a password is ever exposed.
Use your own mobile data instead
The simplest way to avoid public Wi-Fi is to bring your own connection. A travel eSIM gives your phone mobile data without joining anyone else's network, and you can share it with your laptop or tablet using your phone's hotspot. All eSIM2Fly eSIMs support hotspot sharing, subject to what your device manufacturer allows. Our plans are data-only with no hidden roaming fees. Check your phone is compatible on our supported devices page, then browse destinations to find your plan.
If you must use public Wi-Fi
- Connect only to the network staff confirmed.
- Turn on your VPN first.
- Stick to low-risk browsing such as maps, news or weather.
- Log out of accounts when you are done and forget the network.
Staying safe online abroad takes only a few minutes of preparation, and it lets you enjoy the trip without worrying about your accounts.
