Can I just rely on public WiFi?

You can, but it is often inconsistent and insecure. Many public hotspots require a phone number to send an SMS verification code, which may not work if you don't have roaming enabled.

Does my phone work with an eSIM?

Most smartphones manufactured after 2018 (iPhone XS or newer, Samsung Galaxy S20 or newer) are eSIM compatible. Check your settings under 'Cellular' or 'Connections' to see if 'Add eSIM' is an option.

Stay connected to WiFi while traveling in Europe

The most reliable way to stay connected is by using an eSIM app like Airalo or Holafly to get mobile data instantly without swapping physical SIM cards. If you need local WiFi, stick to public hotspots in train stations or libraries and always use a VPN to keep your data secure.

Check your home carrier's roaming policy. Call your mobile provider or check their app to see if they offer a 'day pass' for Europe. If it costs more than $10 per day, skip it and use an eSIM instead.
Install an eSIM before you leave home. Download an app like Airalo or Nomad, purchase a regional Europe plan, and follow the setup steps while you are still on your home WiFi network. Enable it as soon as you land.
Download offline maps and documents. Before heading out, download Google Maps for your specific city and save your boarding passes, hotel addresses, and reservation codes as PDFs on your phone.
Secure your connection. If you connect to public WiFi in a cafe or airport, always toggle on a VPN (Virtual Private Network) like Mullvad or ProtonVPN to encrypt your traffic.
