Hi.

Frequently Asked Questions

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

There are more than 120 travel eSIM brands and over 6, 100 prepaid data plans available for Slovakia, offering a wide variety of options that make it easy for visitors 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. Most of these plans come with a daily or short‑term validity (from one day up to ten days) and are priced roughly between $0 and $28 USD. While the data is unlimited, many of the providers restrict the maximum speed or may throttle traffic during heavy usage. For example, Firsty offers a zero‑cost plan but limits speed to 256 kbps, whereas Yoho Mobile, abesteSIM, Roamify, MicroEsim, and Billion Connect allow speeds up to 5 Mbps, although throttling may still occur. Some other options, such as Truely, Yesim, and FairPlay, also provide unlimited data but typically do not specify a speed limit, though they do mention the possibility of throttling. Travelers can therefore choose from a range of unlimited options and select one that balances price, validity, and expected speed requirements.

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 support SMS while you are in Slovakia are available from several providers. The suppliers that offer such plans are GlobaleSIM, Roamify, SimOptions, and MoreMins eSIM. Each plan allows inbound and outbound voice calls; SMS is available inbound on all of them, and some providers also support outbound SMS. The phone numbers supplied use foreign dialing codes – for example, +1, +33, +44, and +420 – rather than the local Slovak code +421.

Prices for these plans begin around $4 for a 7‑day, 1 GB option and can rise to about $50 or more for a 30‑day, 100 GB package. Validity periods range from 7 days to 180 days, depending on the plan. Travelers who require a local Slovak number would need to select a provider that specifically offers numbers with the +421 code.
