Travel eSIM Czech Republic

These eSIMs don’t include voice minutes - data only. For any calling or texting, you’ll need to rely on VoIP or messaging apps such as WhatsApp, Viber, or Messenger.

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.

No, the Czech Republic eSIM is data-only and excludes voice/SMS numbers. You’ll have to rely on data-based messaging platforms like WhatsApp or Telegram for calling.

Your eSIM will activate automatically once you arrive in Czech Republic. We advise installing your Czech Republic Travel eSIM before you travel (installation is distinct from activation).

To install, just scan the QR code we send or install via the ZenSim app over WiFi. On landing in Czech Republic, the eSIM will switch on by itself.

If you have any problems, check our eSIM Troubleshooting Guide or contact us 😊

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.

Using a travel eSIM trumps roaming in Czech Republic - here’s a quick rundown:

Significant Savings: Pay local Czech Republic rates instead of exorbitant roaming prices set by your home carrier.

Convenient Switching: No swapping SIM cards - manage everything digitally from your phone settings.

Usage Clarity: Get real-time updates on data consumption, so you never get billed for data you didn’t need.

No, your plan only starts upon landing in Czech Republic. Installing beforehand ensures you’re ready to go as the activation will happen automatically.

You’ll need WiFi for installation, so do it before departure and this way you will be connected as soon as you arrive.

If you run into any issues, our eSIM Troubleshooting Guide can help, or contact us directly.

Of course! At ZenSim, we offer eSIMs that support over 200+ destinations, including Czech Republic. On top of this we also provide regional eSIMs which cover multiple countries within one eSIM, please see our Travel eSIMs page for more info on these.

Absolutely. Nearly all of our Travel eSIMs can be extended directly inside the ZenSim app in just a few taps. You can top up extra data, more days, or even include an additional country on the same eSIM, you’ll find everything in the Zen Garden top up section.

Just sign in, head to the Zen Garden, and you’ll spot the option to top up your eSIM straight away.

Top up plan details: The Czech Republic options mirror the website plans, with an added 10% savings.

Longer trips: If your adventure goes beyond 30 days, you can stack as many top ups as you like. Each one activates only after the previous plan ends, so you can buy them in advance without affecting your current eSIM.

Add more countries: Many of our eSIMs now support multi country top ups. For example, if you're using a Europe eSIM and have a stopover in Dubai, simply add a Dubai top up and it will activate automatically when you land without needing a new installation.

Your Czech Republic eSIM is designed for use within Czech Republic, so once it's been activated there, it won’t work in other countries.

If you're visiting multiple destinations, a better option might be one of our regional Travel eSIMs that cover entire regions like Europe or Asia.

Very true! Not only that, you can refer as many people as you like to buy our Czech Republic eSIM, you'll earn a A$5 voucher for each referral - and they will also save A$5 on their order.

There's a couple of things to be aware of, firstly they have to be a new customer for this to apply, and you as the referrer can only use one A$5 voucher per order if you happen to refer a whole lot of friends.

You can view your referral performance and grab your referral URL in the ZenSim app. Visit our terms for more info.

Great question! Our Czech Republic unlimited plans come with a 3GB daily allowance, which is plenty for most travellers - the average person uses under 1GB a day.

If you do blow past that in a single day, your speed drops to 1Mbps until midnight, when your daily allowance resets and you're back to full speed.

If you're on a fixed-data plan instead (say 10GB or 20GB), there's no daily cap at all - use as much as you like until the plan runs out. We'll give you a heads up before that happens, and topping up is just a couple of taps away in the ZenSim app.

Your plan won't start using data or counting down days until you actually arrive in Czech Republic - so there's zero risk in installing it early.

As long as you've already installed your eSIM, it'll automatically activate the moment you land, and that's when your days and data officially kick off.

From there, your eSIM expires when either your data or your days run out, whichever comes first (unless you're on an unlimited plan, in which case it's purely down to the days). So if you grab a 30-day plan, it'll run out 30 days after you arrive in Czech Republic, not 30 days from when you bought it.

Easy way to check - just run your phone through our eSIM compatibility checker and you'll know in seconds whether it'll work with our Czech Republic eSIM and networks.

Still not sure, or something looks off? Reach out to us and we'll sort it out. And if it turns out your phone genuinely can't run the eSIM, our refund policy has you covered with a full refund - so there's no risk in grabbing a plan and giving it a go.

You're covered - our 100% money back guarantee exists for exactly this situation.

Trip cancelled? Phone not eSIM-compatible? Plans changed and you just don't need it anymore? All of these are covered.

The full details sit in our refund policy, but in short: if you can't install or use the eSIM, we'll give you a full refund. You shouldn't have to pay for something you can't use.
