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?

There are more than 220 travel eSIM providers and over 16, 900 prepaid data plans available for Slovakia, and the wide variety of options makes it easy for travelers to find an eSIM that suits their needs.

Are there any unlimited data eSIM plans available for Slovakia?

Yes, several eSIM providers offer unlimited data plans for Slovakia. The available plans generally range from about $1.49 to $25.00 USD, with durations between one and 25 days. Most of these plans allow tethering, but many also include speed throttling, and some impose a maximum speed limit of 5 Mbps, 10 Mbps, or 1 Mbps, depending on the provider. For example, Earth Esim and ASIMGO have plans that may be throttled to 1 Mbps, 5 Mbps, or 10 Mbps, with Earth Esim offering a 5‑day plan for $1.49 and a 25‑day plan for $24.75. Other providers such as Roamify, MicroEsim, Yesim, EtravelSIM, esimzon, abesteSIM, SparkRoam, Numero eSIM, and Orange Travel also offer unlimited data options with varying validity periods and price points. If you need consistent high‑speed data without throttling, be sure to check the specific speed limits listed for each plan before purchasing.

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 eSIM plans that include a phone number and SMS contact in Slovakia are available from several independent providers. Stixrs offers a 20 GB plan for 30 days that includes a local +421 number with inbound and outbound voice and SMS. RedEx eSIM also provides 20 GB packages for 30 days that feature a Slovak +421 number with unlimited calls and 200 SMS, priced around $24.00–$35.00 USD depending on the data tier. GlobaleSIM offers 7 day to 30 day options that give a U.S. phone number (+1) with inbound and outbound voice and inbound SMS, priced from $4.00 to $15.00 USD.

The Slovak‑specific packages give you a true local +421 number, meaning callers will see a Slovak phone number and you can receive SMS normally. Packages that use the +1 code provide a U.S. number; they contain inbound and outbound voice and SMS (though some list only inbound SMS). Prices for these plans generally start around $24 and increase with data size and validity period.
