“Hi.

according to the product description, the O2 Slovakia 5G and Telekom 5G networks should work, but only Telekom 5G works and o2 only 4G. With unlimited Internet in the Europe package, they limit the speed to 10 Mbit”

Slovakia Travel eSIM FAQ

Everything you need to know about using eSIMs in Slovakia

How many travel eSIM brands (providers) are available for use in Slovakia, and how many prepaid data plans are there?

In Slovakia, there are over 130 travel eSIM providers and more than 7, 100 prepaid data plans. This extensive selection gives travelers a wide variety of options, making it easy to find an eSIM that fits their specific needs and usage patterns.

Are there any unlimited data eSIM plans available for Slovakia?

Yes, several eSIM providers supply unlimited data packages for Slovakia, though most impose speed limits or throttling after a certain threshold. Providers such as Firsty, Yoho Mobile, abesteSIM, Roamify, MicroEsim, Billion Connect, Truely, Yesim and FairPlay all offer plans that allow unlimited usage, typically for validity periods ranging from one day up to thirty days. Speed is often capped at 5 Mbps for the majority, with Firsty specifically limiting throughput to 256 kbps and all options permitting tethering. The overall price range for these unlimited plans spans from free with Firsty’s 1‑day offering up to about $30 USD for extended validity periods, giving travelers a range of cost‑effective options to choose from.

What are the major mobile networks available for a travel eSIM in Slovakia?

In Slovakia, the primary Mobile Network Operators (MNOs) are:

Orange Slovensko: A subsidiary of Orange S.A., offering extensive mobile services and covering 99% of the population.
Slovak Telekom: Part of the Deutsche Telekom Group, providing a wide range of mobile services with substantial market presence.
O2 Slovakia: Operated by O2 Czech Republic, offering various mobile services and covering 97.6% of the population with 4G and 84.9% with 5G as of 2024.
4ka (SWAN Mobile): A newer entrant focusing on budget-friendly mobile services, covering around 95% of the population with 4G and 25% with 5G as of 2024.

In addition to these MNOs, Slovakia hosts several Mobile Virtual Network Operators (MVNOs), such as Tesco Mobile, which operates on the O2 network. MVNOs provide mobile services by leasing access from major carriers. However, most travel eSIMs rely on MNO infrastructure rather than MVNOs.

Can I get a travel eSIM with a phone number and SMS for Slovakia?

Travel eSIMs that give you a phone number and SMS capability while visiting Slovakia can be found with a few providers. GlobaleSIM offers plans that include a phone number and inbound SMS, with prices ranging from about $4 for a 1 GB 7‑day data pack to $12 for a 30‑day 20 GB pack. Roamify supplies Slovakia‑named eSIMs that support unlimited calls and up to 200 SMS on a 15 GB 30‑day plan, with prices starting around $15 and extending to $50 for the largest 100 GB offering.

In all of these plans the phone number’s dialing code is not Slovakia’s (+421). GlobaleSIM uses the U.S. dialing code +1, while Roamify’s Slovakia eSIMs use the French dialing code +33. Both providers allow inbound and outbound voice calls; SMS is available inbound on GlobaleSIM and inbound/outbound on Roamify’s offerings. This means you will receive a foreign number rather than a local Slovak one, but you can still receive and send SMS and make international calls through those numbers.
