Can you rely on public Wi-Fi?

Hotels, cafes and airports in Czech Republic usually offer Wi-Fi, but it rarely helps when you need a connection most: navigating between places, checking transport in real time, or calling a ride from the street. Public networks are also unencrypted more often than not. Treat Wi-Fi as a bonus, not a plan.
