I really enjoy the customer service of Simify. They respond so quickly. The service is truly exemplary. I’ve used SImify a few times and will continue to do so. They’re excellent with both coverage and assistance (whether home or overseas)

I’m not very tech savvy so I was a bit hesitant to get an eSIM on my phone but this is my second one through Simify. They have everything you need to know and step-by-step on how to do it. The app makes it easier to keep track of everything too.

I always feel at ease when I travel knowing I have the best eSIM sidekick! I’ve travelled for 4 years and been a long-term user of Simify and I wouldn’t look back 🌏 ❤️

Everything about the process is easy, with immediate help and follow up if required. The customer service is outstanding.

Good prices and plenty of GBs to get you through your trip, Simify has never disappointed and very easy to use. Help is only seconds away if you get stuck on how to use...

I’ve used other eSIM companies in the past, but after trying out Simify I won’t ever waste my time on any others again. Simify has been perfect from purchase through to use. Very easy to follow process which was faultless from the get go. 100% the best international eSIM out there. They’ve won me over for sure. Thanks Simify👍👍🙏

Frequently Asked Questions

  • About the eSIM
  • First-Time Users
  • General
  • Setup & Support
  • Calls & Texts

Can I keep my phone number?

Yes! Your eSIM is for data only, so you can keep your home SIM active for calls and one-time passwords.

Simply make sure Data Roaming is turned off on your home SIM if you want to avoid roaming charges for outgoing calls or texts.

What network will I connect to?

Your eSIM automatically connects to the strongest available network in your area, so you get the best possible coverage and speeds wherever you are.


If signal conditions change, it can seamlessly switch networks in the background to keep you connected.

How far in advance can I buy my eSIM?

Up to 6 months before your trip. Start plan within 6 months of purchase – your plan duration starts once connected to a local network.

How soon will I receive my eSIM?

Right away.

Your eSIM is delivered instantly by email after purchase and is ready to install via the Simify app.

Can I hotspot to other devices?

Yes – our unlimited plans support hotspot and tethering.

Does this eSIM replace my home SIM?

No – and that’s one of the best parts!

Your eSIM works alongside your home SIM. Most travellers use the eSIM for data and keep their home SIM active for calls, texts, and one-time passwords. You stay connected without giving up your number.

Just make sure Data Roaming is turned off on your home SIM if you want to avoid roaming charges for outgoing calls or texts.

What is an eSIM and how does it work?

An eSIM is a digital SIM that’s already built into your device, so there’s no physical SIM card needed.

Just check your device is compatible, choose a plan, and install it instantly. Once you arrive at your destination, your eSIM connects to a local network so you can get online straight away – no SIM swapping or hunting for Wi-Fi.

When should I activate my eSIM?

We recommend installing your eSIM before you travel while connected to Wi-Fi.

It won’t activate until you arrive and connect to a local network. Once you land, simply make sure the eSIM is switched on in your device settings and you’re good to go.

Will I lose my contacts, WhatsApp, or phone number?

No. Everything stays the same – your home SIM, contacts, and apps are unaffected.

What if it doesn’t work when I land?

First, restart your phone – most issues are solved immediately this way.

If needed, follow the simple troubleshooting steps in our Help Centre or contact our 24/7 support team.

I’ve never used an eSIM before. Will it be hard?

Not at all! Most customers are set up in just a few minutes. Step-by-step instructions are provided in your email and the Simify app.

Plus, with our Money Back Guarantee, you’re covered with a full refund if there’s an issue we can’t resolve.

Which plan is right for me?

Why choose unlimited?
Unlimited plans are our most popular option because you don’t have to track data usage or worry about running out. Use maps, messages, bookings, and apps freely throughout your trip.

Prefer a fixed data plan?
Fixed plans are a great choice if you know roughly how much data you’ll use and mainly need connectivity for essentials like maps, messaging, and browsing.

It then comes down to where you’re travelling:

Travelling to one destination?
Our country plans are ideal for staying connected in a single destination.

Visiting multiple destinations in the same region?
A regional plan lets you stay connected as you move between nearby countries without switching eSIMs.

Travelling across different regions or with multiple stopovers?
Our Global plan offers extra peace of mind, keeping you connected across multiple regions and even during layovers.

Not sure which plan covers your destination?
Use the search bar at the top of the page to quickly find the right plan for your trip. Always check the coverage listed on the product page to make sure your destinations are included.

What speeds can I expect?

4G and 5G in most cities and towns; speeds may be slower in remote areas.

Can I buy an eSIM for a friend? How does it work?

Yes! You can send an eSIM to a friend via email through the Simify app under My eSIMs. We also offer discounts when purchasing more than one eSIMs.

Can I top up my eSIM?

Yes, if you're on an Unlimited plan. You can add more days to your existing eSIM in the Simify app, so you don't need to install a new one.

You have 180 days after your plan ends to top up. That means you can keep your eSIM installed and top it up for your next trip, with no need to reinstall.

Top-ups aren't available on fixed data plans yet, but we're currently exploring building this. Until then, you can buy a new eSIM in the app or on our website and be connected in minutes.

Who are travel eSIMs best for?

Travel eSIMs are perfect for anyone who wants reliable internet while overseas – from holidaymakers and business travellers to digital nomads and frequent flyers.

They help you avoid roaming charges, skip local SIM shops, and stay connected on trusted local networks wherever you go.

Why should I choose an eSIM instead of roaming or a physical SIM?

eSIMs are simpler, more flexible, and often more affordable.

You can keep your home SIM in place, avoid expensive roaming fees, and get online as soon as you land. That means easy navigation, instant messaging, bookings on the go, and staying connected without hassle.

What if my travel plans change?

No worries! Under our 100% Money Back Guarantee, you can request a refund if your trip is cancelled or delayed.

What is the Fair Usage Policy?

Your eSIM includes unlimited data for the full duration of your plan. In some cases, local network providers manage traffic during very high usage periods – if this happens, speeds may be temporarily reduced for a short time (typically up to 24 hours) before returning to normal on their own.

This is uncommon but if you're ever in need of it being refreshed, our customer service team can help reset things for you – just reach out and we'll sort it out quickly.

How do I install my eSIM?

  1. Download the Simify app and log in with your purchase email

  2. Follow the installation guide under My eSIMs (automatic setup is fastest)

  3. Turn on your eSIM once you land

Full guides are also available in the Help Centre.

Can I store multiple eSIMs on my device?

Yes. Most devices store multiple eSIMs, though only one can be active for data at a time. Switching is simple via phone settings.

When does my eSIM plan start?

Your plan starts when the eSIM first connects to a local network at your destination. From that moment, your selected number of days begins counting down.

How can I confirm my eSIM is installed correctly?

Check your mobile settings – the eSIM should appear. When you arrive, enable it as your primary data plan, turn on Data Roaming, and restart your device if needed. Support is available anytime if you get stuck!

How do I know if my phone is unlocked?

Most devices are unlocked. If unsure, test with another SIM or contact your carrier. Phones on a plan may require unlocking first.

Are calls and texts included?

Our eSIMs focus on data, which means you can still call and message using apps like WhatsApp, FaceTime, iMessage, Viber, and more! all through your data connection.

If you plan to use traditional calls or texts, you can keep your home SIM switched on alongside the eSIM. In most cases this works automatically, but availability depends on your mobile plan. Your carrier can confirm this for you, and roaming charges may apply while you’re overseas.

Can I receive calls and texts on my home number while overseas?

Yes. You can use your home SIM alongside the eSIM to receive calls and texts as normal.

Most carriers allow this by default, but we recommend checking with your carrier before you travel – especially if you rely on one-time passwords. Incoming texts are usually free, while calls or outgoing messages may incur roaming charges depending on your carrier.

How can I make international calls home?

VOIP apps like Viber are affordable options. Simply add credit and use your eSIM data connection.

How can I call local businesses overseas?

Use VOIP apps like Viber, or contact businesses via WhatsApp or email. Many hotels also provide guest landlines.

Can I keep my WhatsApp number and chats?

Yes, everything stays exactly the same. Your number, contacts, and chat history are preserved automatically.

Unlimited Czech Republic eSIM

Czech Republic eSIM FAQs: your questions, answered

How do I buy a Czech Republic eSIM online?

You can buy a Czech Republic eSIM online from Simify in a couple of minutes — choose your plan, pay securely, and your eSIM QR code arrives by email within minutes. Because you buy your eSIM for the Czech Republic before you fly, you can install it at home on Wi-Fi and simply connect when you land.

Which Czech Republic networks and eSIM providers does Simify use?

As a trusted Czech Republic eSIM provider, Simify connects to the leading local mobile networks in the Czech Republic and automatically selects the strongest available signal, and you can switch networks manually any time. You get reliable coverage without having to compare a long list of Czech Republic eSIM providers or buy a local SIM on arrival.

What Czech Republic eSIM plans are available?

We offer flexible Czech Republic eSIM plans to match your trip: a fixed-data plan for shorter or lighter stays, and an Unlimited plan for heavier users. Every plan is data-only and supports hotspot and tethering — just note that sharing uses data faster, so the Unlimited plan suits heavy hotspot use best. There’s a Czech Republic eSIM plan whether you’re visiting for a weekend or a month.

Is there an unlimited data eSIM for the Czech Republic?

Yes — Simify offers an Unlimited Czech Republic eSIM, so you can stay connected for the whole plan period and use your phone freely for maps, social and messaging without watching a data meter. Choose the plan length that suits your trip, from short stays up to 180 days — it’s the easy, stress-free choice for day-to-day travel.

How much does it cost — is this a cheap Czech Republic eSIM?

Simify is one of the most cost-effective ways to stay connected in the Czech Republic. A prepaid Czech Republic eSIM avoids the expensive per-day roaming the big carriers charge, with clear upfront pricing and no surprise bills. Plans are priced by trip length and data, and first-time customers can unlock a discount by signing up to the Simify newsletter — so it typically works out far cheaper than telco roaming.

Is it a prepaid or pay-as-you-go Czech Republic eSIM?

Yes — every Simify Czech Republic eSIM is prepaid, so it works on a simple pay-as-you-go basis: pay once up front, with no contract and no postpaid bills. If your trip runs long, you can top up an eligible Unlimited eSIM with extra days in the Simify app, or choose the unlimited option up front. No surprises, no bill shock with our prepaid Czech Republic eSIM.

Is this a good tourist eSIM for the Czech Republic and short-term visitors?

Definitely. Our Czech Republic tourist eSIM is built for travellers and short-term visitors — no passport, no local address and no shop queue required. It’s a popular choice among Czech Republic eSIM providers for tourists because you can set it up at home before you fly and connect the moment you land.

Do I get a physical Czech Republic eSIM card, or is it digital?

A Czech Republic eSIM is a digital SIM — there’s no physical eSIM card to insert. Your phone downloads the profile from a QR code. If you’d prefer a physical Czech Republic SIM card as a backup for an older device we offer that too, but most modern phones only need the digital e-SIM.

Does the Czech Republic eSIM come with a Czech Republic number?

No — Simify Czech Republic eSIMs are data-only, so they don’t include a local phone number or traditional calls and texts. The eSIM runs alongside your home SIM so you keep your existing number, and you can call and message over data using WhatsApp, iMessage or FaceTime. Keep your home SIM switched on if you still want to receive standard calls or one-time passcodes (SMS).

Is this a travel eSIM for the Czech Republic?

Yes — Simify is a purpose-built travel eSIM for the Czech Republic. It gives Aussie travellers fast internet and data the moment they land, with no roaming fees and no SIM swapping. Whether it’s a city break or a month exploring the country, our Czech Republic travel eSIM keeps you online.

Will my eSIM work on public transport and intercity travel in the Czech Republic?

Yes. Your eSIM has nationwide coverage across the Czech Republic including its major cities. Signal may briefly vary in tunnels, mountains or remote stretches but reconnects quickly — you can check routes and timings on Google Maps throughout your trip, in the city or heading further out.

Can I book a rideshare or taxi at the airport as soon as I land?

Absolutely. Turn data roaming on when you land and you’ll have an immediate 5G/4G connection — open Uber, Bolt or FreeNow and book your ride while you’re still walking to arrivals, no airport Wi-Fi queue needed.

What if my trip includes nearby countries?

Czech Republic-only plans cover the Czech Republic. If your trip includes France, Italy, Spain or other European countries, choose our Europe & UK eSIM — data works across the region with no profile switching. For a bigger multi-country trip, our unlimited Global eSIM keeps you online across dozens of countries.

When does the eSIM activate, and when should I install it?

Installing your eSIM doesn’t start your plan — validity begins when it first connects to a supported network at your destination, so you can buy and install up to 180 days before you travel. Keep the eSIM line switched off until you arrive, then turn it on and enable data roaming to connect. That way your plan won’t start early.

What’s the difference between an e-SIM and a normal SIM for the Czech Republic?

An e-SIM (or “e sim”) is a digital SIM built into your phone — there’s no plastic Czech Republic e-SIM card to insert or swap. For the Czech Republic it simply means you download your plan and connect while your normal SIM stays in place. Every Simify Czech Republic e-sim is data-only and runs alongside your existing SIM.

Which is the cheapest Czech Republic eSIM plan, and are there any deals?

The best-value Czech Republic eSIM depends on your trip: shorter or lighter trips suit a fixed-data plan, while longer or heavier trips suit the Unlimited plan. First-time customers can unlock a discount by signing up to the Simify newsletter, and multi-trip or multi-country bundles can save more again — so it works out cheaper than telco roaming either way.

How much Czech Republic data do I get, and is it a data-only eSIM?

Every Simify Czech Republic eSIM is a data-only plan — great for maps, social and staying in touch over WhatsApp, iMessage or FaceTime. Fixed plans come with a set data amount for your trip, while the Unlimited plan gives you high-speed data throughout your plan period. Just pick the Czech Republic data eSIM that matches how much you expect to use.

Can one eSIM cover the Czech Republic and other countries?

Yes. Alongside our Czech Republic-only plan we offer a Europe & UK eSIM covering the Czech Republic plus neighbouring countries, and an unlimited Global eSIM — handy when Czech Republic is one stop on a bigger trip. One eSIM covers multiple countries with no reinstalling at the border, and all plans are data-only.

Does the Czech Republic eSIM give me internet right across the Czech Republic?

Yes — your Czech Republic eSIM provides mobile internet right across the Czech Republic on major local networks, including its major cities. Coverage is near-total in cities and towns; speeds can dip in remote or rural areas, so it’s worth downloading offline maps for those stretches.

Which Czech Republic eSIM plan should I choose for my trip?

For a short city break, a smaller fixed Czech Republic eSIM data plan is usually plenty; for longer trips or heavier use, the Unlimited plan won’t stop mid-trip and is better value. Match the plan’s data and validity to your travel dates — and if you’ll hotspot a laptop or tablet, the Unlimited plan handles that best.

Is Simify a Czech Republic eSIM provider I can trust as a tourist?

Simify is an established travel-eSIM provider used by over 1,000,000 travellers and rated Excellent on Trustpilot. Instead of scrolling a long Czech Republic eSIM providers list, you get one trusted provider on major Czech Republic networks, with friendly human support and a 100% money-back guarantee if your eSIM doesn’t work and you’ve contacted our team.

How do I set up and connect my Czech Republic eSIM?

After you buy, your QR code arrives by email. Install it on Wi-Fi before you fly (installing won’t start your plan), keep the eSIM turned off until you arrive, then switch it on and turn data roaming on to connect. Setup takes a couple of minutes — no shop visit and no passport needed.
