Czech Republic eSIM FAQs
No, our Czech Republic travel eSIMs do not include any phone number - they strictly provide internet data. For calls, use data - driven apps such as WhatsApp, Signal, or Facetime.
Nope - the eSIM waits for you to land in Czech Republic before beginning data usage or counting plan days, unless of course you're already in Czech Republic then yes it will start using data immediately.
We advise installing before departure over WiFi so you can be connected as soon as you land on the tarmac.
For any connection hiccups, check out our eSIM Troubleshooting Guide or get in touch.
Your eSIM will activate automatically once you step off the plane in Czech Republic. We do suggest installing your Czech Republic Travel eSIM before departure (installation ≠ activation).
Installation is a breeze: scan the QR code provided or install via the ZenSim app over WiFi. Upon landing, the eSIM will activate itself.
Encountering issues? Visit our eSIM Troubleshooting Guide or contact us 😊
Of course. You can install your Czech Republic eSIM up to 30 days before departure. Once you arrive, it will activate automatically.
Installing early won’t use any data or start your plan until you arrive in Czech Republic.
If your iPhone shows an activation error during pre-install, you can ignore often it - refer to our eSIM Troubleshooting Guide for help.
Once activated in Czech Republic, your eSIM typically won’t function outside that country.
If you're planning to hop between countries, we recommend checking out our regional Travel eSIMs - they’re made for multi-country use and cover most major regions.
Hands down, a travel eSIM beats roaming in Czech Republic. Here’s why:
Cheaper Data: Pay local prices rather than roaming surcharges from your home network.
Instant Setup: No waiting for physical SIM delivery - your eSIM is ready the minute you land.
Full Expense Control: Track data usage and spending in - app, so you avoid surprise fees.
Once you arrive in Czech Republic, your eSIM activates automatically if it’s already installed.
If you install it after arriving, the eSIM will activate and begin working immediately.
For any setup or connection problems, refer to our eSIM Troubleshooting Guide or contact our support.
No, the Czech Republic travel eSIM is data - only. It won’t give you a cellular voice line. If you want to call, just fire up WhatsApp, Telegram, or FaceTime using your data allowance.
