Slovakia: 10 Best eSIMs Compared + Discounts (2022)

Slovakia – known for its castles, folk dancing & landscapes.

Apparently, the country has the highest concentration of castles worldwide.

So, castle lovers – you know where to go to.

But besides castles, what else can you do in Slovakia? A lot.

Many churches, like The Blue Church, are worth visiting.

If you love nature and hiking, head to the mountains, and you will love the landscapes.

And if you are into skiing, skip Austria and ski in Slovakia – it will be much cheaper.

As you can see, the country has a lot to offer.

What it cannot offer you, unless you have an EU/EEA SIM card, is low international roaming rates.

Dealing with an expensive international roaming bill will certainly not be enjoyable because you forgot to turn off international roaming.

Instead, if your phone supports eSIM, you may want to go with a travel eSIM to skip the queues in Slovakia and avoid the SIM card registration bureaucracy.

So, how much do Slovak (travel) eSIMs cost?

You can get an eSIM for Slovakia for as low as 4.50 USD up to 99 USD from Airalo (with Dobrý Deň), Holafly & Nomad, offering between 1 GB and truly unlimited data.

There are some mobile operators who will charge you 100 USD for only 100 MB of roaming data, so these travel eSIM offers are much better than most international roaming deals.

In this guide, I will go over the eSIM options offered by the Slovak mobile operators, Airalo, Holafly & Nomad. Let's get started.

eSIMs offered by Slovak Mobile Operators

In order to get the best performance out there, it is often recommended to go directly with the local mobile operators because you will get a higher priority on the network compared to roaming.

Currently, Slovak Telekom (formerly T-Mobile), Orange Slovakia, O2 Slovakia & 4ka (by Swan Mobile) offer eSIMs to prepaid customers.

Note that the Slovak mobile operators require your identification (ID for EU/EEA travelers and passport for anyone else) for eSIMs and physical SIM cards as part of Slovakia's SIM card registration requirements, as SIM card registration is mandatory in Slovakia.

Travel eSIM providers Airalo (with Dobrý Deň), Holafly & Nomad offer attractive eSIMs for Slovakia, allowing them to be set up before arriving in the country and activating them as soon as you land.

Very convenient, right? And I have used eSIMs from Airalo, Holafly & Nomad before, and I can assure you they work well!

So let's check out all the options, shall we?


Airalo eSIMs for Slovakia (Dobrý Deň)

Airalo eSIMs are my favorite travel eSIMs out there because they are always good value for money compared to other travel eSIM providers (especially travel eSIMs not mentioned in this guide).

And the same can be said for the Dobrý Deň eSIM – 10 GB of data is available for only 22 USD.

The Dobrý Deň eSIM uses the O2 Slovakia network, which is the best overall Slovak mobile operator (coverage and speed-wise).

So even if you go to some remote Slovak town, you will still have reception with the Dobrý Deň eSIM.

Alright, you have four Slovakia Dobrý Deň eSIM options:

  1. Slovakia/Dobrý Deň 1 GB eSIM for 7 days, costing 4.50 USD
  2. Slovakia/Dobrý Deň 3 GB eSIM for 30 days, costing 9 USD
  3. Slovakia/Dobrý Deň 5 GB eSIM for 30 days, costing 13 USD (most popular with Phone Travel Wiz readers)
  4. Slovakia/Dobrý Deň 10 GB eSIM for 30 days, costing 22 USD (most popular with Phone Travel Wiz readers)

When I say that the 5 GB & 10 GB variants are loved by Phone Travel Wiz readers, all readers get either the 5 GB or 10 GB variants.

So yeah, they are really popular.

For Airalo eSIMs, the links above will automatically get you the Phone Travel Wiz exclusive offers available – a code is not necessary.

Honestly, the Dobrý Deň eSIM gives you the best bang for your buck, and it is the eSIM I recommend the most for Slovakia.

Airalo Dobrý Deň eSIM Pros

So, why should you get the Dobrý Deň eSIMs? Well, because of the following:

But it is not all good news with Airalo though – there are some disadvantages.

Airalo Dobrý Deň eSIM Cons

So, why should you not get the Dobrý Deň eSIM?

  • The Slovak mobile operators have much more generous data allowances
  • While you get access to O2 Slovakia's network, the best in Slovakia, your speeds will not be as fast as going with O2 Slovakia itself because you will be roaming on their networks (and not be a native customer)
  • There is no 5G NR access with the Dobrý Deň eSIM
  • You cannot call or text with the Dobrý Deň eSIM (nor can you receive them – you get no (local) phone number)
  • You cannot get in-person support (Airalo gets back to you by email fast, but you cannot visit an Airalo store because there are none)

Airalo Dobrý Deň eSIM Overall Thoughts

Overall, the Airalo Dobrý Deň eSIM is a great eSIM offering a lot for the money you pay (especially compared to many non-EU countries).

You get fast speeds and access to the best Slovak network (O2 Slovakia) without standing in queues or dealing with SIM card registration bureaucracy.

But if making actual phone calls and sending real text messages are important to you (so not through an app like WhatsApp), you may want to buy a Slovak SIM card instead.


Holafly eSIMs for Slovakia

The second eSIM provider I recommend is Holafly.

It started something revolutionary in June 2022.

Holafly offers unlimited data plans for Slovakia, many other European Union member states, and a few other countries.

From what I know, Holafly is the first to offer unlimited data plans for so many countries WITHOUT a Fair-Use Policy.

And that is super exciting!

Now, I have to say that the unlimited data plans offered by Holafly are more expensive than the Airalo Dobrý Deň eSIM or the eSIMs sold by Nomad.

But if you do not want to worry about data allowances, Holafly is the one to go for.

The Holafly eSIMs use the Slovak Telekom network, which has the second-fastest speeds in the country.

You have the following seven options with Holafly:

While I do not know which variant Phone Travel Wiz readers go with, I can tell you that the Holafly eSIMs are popular with those who simply do not want to worry about data caps.

And based on the emails I have received, the 20-, 30- & 60-day plans are popular because those who buy Holafly eSIMs tend to stay in Slovakia for a prolonged period to explore the country.

As I recently started my collaboration with Holafly, it offers 5% off each purchase whenever you use code PHONETRAVELWIZ – how cool is that?

Of course, there are some pros and cons with going with Holafly, so let's go over them.

Holafly Slovakia eSIM Pros

So, why should you get the Holafly eSIMs? Well, because of the following:

But it is not all good news with Holafly though – there are some disadvantages.

Holafly Slovakia eSIM Cons

So, why should you not get a Holafly Slovakia eSIM?

  • While the Slovak mobile operators do not offer unlimited data plans (yet), their plans are much cheaper than Holafly
  • While you get access to the Slovak Telekom network, your speeds will not be as fast as going with Slovak Telekom itself because you will be roaming on their networks (and not be a native customer)
  • There is no 5G NR access with the Holafly eSIM
  • You cannot call or text with the Holafly eSIM (nor can you receive them – you get no (local) phone number)
  • You cannot get in-person support (Holafly gets back to you by email fast, but you cannot visit an Holafly store because there are none)
  • Holafly is the most expensive travel eSIM provider in this guide

Holafly Slovakia eSIM Overall Thoughts

Overall, the Holafly Slovakia eSIM is an excellent eSIM for those who hate data caps and just want to use data the way they want.

You get access to the Slovak Telekom network.

However, Holafly is the most expensive option in this guide and may not be the best for budget travelers.

Luckily, we still have one more Slovakia-specific travel eSIM to go through, which is cheaper than Holafly.


Nomad eSIMs for Slovakia

The last eSIM provider I recommend is Nomad.

Nomad is just in the middle.

But that does not mean Nomad is bad – not at all.

The Nomad Slovakia eSIM uses the Truphone network, which is also active in any country you can think of.

In Slovakia, the Nomad uses a combination of networks, allowing your eSIM to switch to the network with the best reception automatically.

This way, you will always be connected!

Nomad is a bit more expensive than Airalo's Dobrý Deň eSIM but cheaper than Holafly.

That is because, unlike the other two eSIM providers, the Nomad Slovakia eSIM uses a combination of several Slovak networks (O2 Slovakia and Slovak Telekom), allowing you access to the best network at your location.

And for this feature, you pay a little more than Airalo, which only uses O2 Slovakia.

You have the following four options with Nomad:

  1. Slovakia 1 GB eSIM for 7 days, costing 9 USD/9 EUR/7.50 GBP/12 CAD
  2. Slovakia 3 GB eSIM for 30 days, costing 17 USD/17 EUR/14.50 GBP/22 CAD
  3. Slovakia 5 GB eSIM for 30 days, costing 18 USD/18 EUR/15 GBP/23.50 CAD
  4. Slovakia 10 GB eSIM for 30 days, costing 26 USD/25.50 EUR/22 GBP/33.50 CAD
Slovakia eSIMs Nomad

By the way, you can get 3 USD off of your first Nomad purchase by using code ADU123 – how cool is that?

Of course, going with Nomad has some pros and cons, so let's go over them.

Nomad Slovakia eSIM Pros

So, why should you get the Nomad eSIMs? Well, because of the following:

But it is not all good news with Nomad though – there are some disadvantages.

Nomad Slovakia eSIM Cons

So, why should you not get a Nomad Slovakia eSIM?

  • While you get access to three networks, your speeds will not be as fast as going with the Slovak mobile operators themselves because you will be roaming on their networks (and not be a native customer)
  • There is no 5G NR access with the Nomad Slovakia eSIM
  • You cannot call or text with the Nomad Slovakia eSIM (nor can you receive them – you get no (local) phone number)
  • You cannot get in-person support (Nomad gets back to you by email fast, but you cannot visit a Nomad store because there are none)
  • Airalo is cheaper than Nomad with all variants

Nomad Slovakia eSIM Overall Thoughts

Overall, the Nomad eSIM is a great premium eSIM offering.

You will always have the best reception because Nomad automatically switches to the best network at your location.

However, just like the other travel eSIMs mentioned in this guide, you do not get a (local) phone number with the Nomad Slovakia eSIM.

Moreover, Nomad is not the cheapest option out there (that would be Airalo).


Best eSIMs for in Europe (not just Slovakia)

So what if you plan to visit neighboring Hungary? Poland? Ukraine? Or any other country in the European Union?

Unfortunately, you cannot use your Airalo Dobrý Deň, Holafly Slovakia, or Nomad Slovakia eSIMs in any other country than Slovakia.

However, the three eSIM providers do have eSIMs covering all of the European Union and European Economic area + some other countries.

I highly recommend these Europe eSIMs if you plan to visit multiple European countries to save money!

Airalo Eurolink Europe eSIM

The Eurolink eSIM is the most popular Airalo eSIM, per Phone Travel Wiz readers.

Most readers tend to visit multiple European countries, so they would rather have a travel eSIM covering multiple countries than just one (like Slovakia).

The Eurolink eSIM can be used in 39 countries in Europe, including all nations in the European Union (EU).

The eSIM can be used from Iceland to Ukraine and Norway to Spain.

Below is a complete overview of countries the Eurolink eSIM works in:

With the Eurolink eSIM, you can save a lot of money by skipping the initial SIM card costs per country you visit – averaging 10.78 USD/country in Europe!

Below is an overview of how much each Eurolink eSIM costs:

  1. Europe/Eurolink 1 GB eSIM for 7 days, costing 5 USD
  2. Europe/Eurolink 3 GB eSIM for 30 days, costing 13 USDmost popular with Phone Travel Wiz readers
  3. Europe/Eurolink 5 GB eSIM for 30 days, costing 20 USDvery popular with Phone Travel Wiz readers
  4. Europe/Eurolink 10 GB eSIM for 30 days, costing 37 USDvery popular with Phone Travel Wiz readers
  5. Europe/Eurolink 50 GB eSIM for 90 days, costing 100 USD
  6. Europe/Eurolink 100 GB eSIM for 180 days, costing 185 USD
Eurolink Europe eSIM Airalo (with Prices)

Honestly, the Eurolink eSIM is my favorite Europe travel eSIM out there. Affordable, extensive & good value for your money.

I also used it during my 1-month tour throughout Europe in 12 countries.

Airalo Eurolink eSIM Review by Phone Travel Wiz

So yeah, you can say I have some experience with the Eurolink eSIM 😏.

Holafly and Nomad eSIMs for Europe

Holafly and Nomad also have eSIMs covering all of the European Union (and more).

But honestly, the Eurolink eSIM is superior (but you can consider the Holafly Europe eSIM if you want unlimited data in 30+ countries – just do not forget about code PHONETRAVELWIZ if you go with Holafly).


Overview of the Best eSIMs for Slovakia (Airalo vs. Holafly vs. Nomad)

Unfortunately, none of the Slovak mobile operators offer eSIMs to prepaid customers.

But that is fine – we discussed several other options in this guide!

In terms of the travel eSIMs, this would be my recommendation order:

  • Airalo's Dobrý Deň Slovakia eSIM (best value for money)
  • Airalo's Eurolink Europe eSIM (best value for money when also visiting other European countries)
  • Holafly Slovakia eSIM (truly unlimited data plans at premium prices)
  • Nomad Slovakia eSIM (switches to the best network, allowing for excellent reception at all times)
  • Holafly Europe eSIM (truly unlimited data plans when also visiting other European countries at premium prices)
  • Nomad Europe eSIM (the best of both worlds in terms of pricing and performance)

Remember to use code PHONETRAVELWIZ for Holafly eSIMs and code ADU123 for Nomad eSIMs – a code is not necessary for Airalo eSIM purchases.


Buying a SIM Card in Slovakia

Want to just use a SIM card but not your current one because roaming will be criminally expensive?

Consider getting a Slovak SIM card instead – local SIM cards are the cheapest way to stay connected abroad.
