How does a Czech Republic eSIM work?

An eSIM is an embedded SIM card, and you probably already have an eSIM-compatible device. When you install an eSIM for a country or region, it lets your device connect to local networks in that area. This means your device will have data without needing Wi-Fi or paying roaming charges.
