Czech Republic eSIM

This plan's days start when the eSIM first connects to a network in its coverage area, not when you buy or install it. Some other Czech Republic plans start differently. Each plan's page shows its rule under Activation.

Most Czech Republic plans are data-only, with no phone number for calls or texts. Plans marked Call include a phone number, call minutes and text messages (SMS). On a data-only plan you can still call and message over apps like WhatsApp.

Once you purchase an eSIM, you will receive it immediately to your email address. You then scan the QR code to install the eSIM. If you have not installed, activated or used your eSIM, you can ask us to review a refund within 30 calendar days of purchase, when the order is linked to your Roamify account email. See our refund policy for more information.

You don't need to do anything to keep your WhatsApp number. You'll automatically keep your number, contacts and conversations.

The Roamify eSIM offers maximum speed coverage. But bear in mind that in some areas of limited coverage there may be a lower speed connection.

Yes. To ensure that your eSIM gets the best coverage, you must turn on data roaming on your mobile settings. This will not incur any additional charges, as long as you have already set up the eSIM.

Not always. This plan connects through a roaming partner, so websites and apps may see an IP address registered in another country rather than in Czech Republic. This is normal for travel eSIMs and does not change your data allowance, speed or coverage. If a service requires a local IP address, such as some banking apps or regional streaming catalogues, connect through a local network or use a VPN set to Czech Republic.

If you cannot find the code, please contact our 24/7 customer support team at support@getroamify.com or our online chat function. We will resend the code to your email.

On Czech Republic Unlimited plans, full speed lasts up to 1 GB, then data is slowed to 5 Mbps, not cut off. On Czech Republic plans with a fixed amount of data, data stops or is slowed after a set amount, depending on the plan; on some plans that happens before all of the plan's data is used. Some of them can be topped up with more data. Each plan's page shows its rule under Fair use policy. When the plan's days run out, your eSIM stops working and you lose its internet connection.

You can choose variable plans as shown above. You can contact us at any time if you're not sure which plan is best for you.

On Czech Republic Unlimited plans, full speed lasts up to 1 GB, then data is slowed to 5 Mbps, not cut off. If your connection seems slower than that, contact us by chat and we will check it.

This plan can't be topped up, but some other Czech Republic plans can: check Top-up in a plan's details before you buy. Otherwise, buy a new Czech Republic plan when this one runs out.

Yes, you can share data with other devices. You can do this by activating the hotspot on your device.

Once you make your purchase, we will send you an email with precise instructions to install your eSIM in two ways: by scanning the QR code or by copying and pasting the manual installation codes. To install with the first option, it is essential that the QR code is printed or on another device. Otherwise, you can follow the manual installation instructions for your Roamify eSIM. If your device is iOS, go to Settings → Cellular → Add eSIM and scan the QR code or paste the manual installation codes sent to your email. Then follow the on-screen instructions and choose your new eSIM as the line for mobile data. If your plan includes calls or texts, choose the Roamify eSIM as the line for those too. On a data-only plan, keep your physical SIM as the line for calls and texts. If your device is Android, follow the instructions we will email you to install your Roamify eSIM. When you are in Czech Republic, select your Roamify eSIM for mobile data and turn on data roaming for it. At Roamify, we want to make setting up your eSIM as easy as possible. For this reason, all our eSIM products come with complete instructions for easy setup. If you have any questions or need help, don't hesitate to contact our customer support team. We will be there for you 24/7.

You can install this plan a day or two before you travel, over Wi-Fi. Its days start only when it first connects to a network in its coverage area. When you are in Czech Republic, select the Roamify eSIM for mobile data and turn on data roaming for it. An installed eSIM is generally no longer refundable. See our refund policy.

To check your remaining data, log in to our web app with the access details we emailed you when you made your purchase. You can also check your data use in your device's mobile data settings.

Your eSIM can only be activated on one device. If you delete the eSIM from your device, you will not be able to reuse it. You cannot scan the QR code on two devices.

You don't need to delete the eSIM. But if you want to, please see how to delete eSIM on iOS and Android.

Yes. Choose the Roamify eSIM as the line for mobile data in your device settings. On a data-only plan, keep your physical SIM for calls and texts; if your plan includes calls or texts, choose the Roamify eSIM as the line for those too. If data roaming stays on for your physical SIM, your home network provider may charge roaming fees, so turn it off for that line.

Most unused eSIM purchases are eligible for a refund review when you send your request within 30 calendar days of purchase. To qualify, the eSIM must not be activated, installed, or consumed, and the order must be linked to your Roamify account email. Once an eSIM has been activated or installed, or has recorded data usage, it generally cannot be refunded. Please see our eSIM Refund Policy for the full terms.

Roamify's Czech Republic eSIM connects to O2, Vodafone, as listed for every plan on this page.
