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 110 providers and 5, 700 prepaid data plans available for Slovakia, offering a wide variety of options that make it easy for travelers to find an eSIM that suits their needs.

Are there any unlimited data eSIM plans available for Slovakia?

Unlimited data eSIMs for Slovakia are available from a number of providers. Firsty offers an ad‑supported plan that is free but limits speed to 256 kbps and lasts only one day. Other operators such as Yoho Mobile, Roamify, MicroEsim, Billion Connect, abesteSIM, Truely, Yesim, Airhub and FairPlay provide unlimited data for periods ranging from one to fifteen days. Most of these plans may throttle speed, with a few specifying a maximum of 5 Mbps; first‑time users may be affected by additional restrictions. Prices for the unlimited options start at about USD 0 and rise to roughly USD 27.40, so travelers can select a plan that fits their budget while keeping in mind that speeds could be reduced after heavy use.

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 are available for Slovakia, but the numbers are not local Slovak numbers. Providers such as GlobaleSIM and Roamify offer plans with foreign dialing codes: GlobaleSIM uses +1 and Roamify’s Slovakia eSIMs use +33. Both providers give inbound and outbound voice and inbound SMS, with Roamify also offering outbound SMS. These plans provide a working phone number that can receive calls and texts from any operator, though callers will see a foreign country code.

The plans start at around $4 for a 7‑day data bundle and can go up to about $45.60 for 30 days of data. Validity periods range from 7 days to 30 days, and data caps vary from 1 GB to 15 GB. If a local Slovak number is required, you might consider using VoIP apps such as WhatsApp or Telegram over the data included in the eSIM.
