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.
The easiest way to get online
A prepaid eSIM for Czech Republic installs on your phone before you leave home and connects to a local network automatically when you land — no store visits, no paperwork, no roaming fees. Plans start at $0.97.
