Do You Need a VPN on Public Wi-Fi and When You Travel?

What the VPN changes on shared Wi-Fi

On hotel, café, and airport Wi-Fi, other people can share the same network. A VPN encrypts the stretch between your device and the provider’s server, so the local network and the café’s ISP do not see each site you open. They see a connection to the VPN. That is useful. It does not stop a phishing page, a malicious app, or a site you logged in to from knowing who you are.

The practical pieces are an app that reconnects after the network drops, a kill switch while that happens, and a protocol such as WireGuard that is fast enough that you will leave it on.

Match the term to the trip

A two-week trip does not need a 24-month plan. Use a monthly plan, finish the trip, and decide later if you want the longer discount. A year or two makes sense when you already know you will keep the same apps on the same devices.

For travel, check that the provider has apps for the phone and laptop you are taking, and that it lists servers in the countries you care about. NordVPN publishes the widest coverage in this comparison. LockNet VPN lists 30+ countries and mentions Fire Stick and router support. DombayVPN describes its own servers in Europe and Asia and is aimed at networks that block ordinary VPN traffic.

A VPN is not a travel permit

Some countries restrict VPN use. A comparison site cannot tell you what is legal where you are landing. Check the local rule before you rely on an app. If a network is built to block VPN traffic, a standard server may not connect. That is the use case DombayVPN describes. It is also why “it worked at home” is not a test of a hotel network abroad.
