“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?

Slovakia offers roughly 150 travel eSIM providers and more than 8, 800 prepaid data plans, providing travelers with a wide range of options to choose from.

Are there any unlimited data eSIM plans available for Slovakia?

Unlimited data eSIM plans are available from several providers that serve Slovakia. Providers such as Firsty, abesteSIM, Roamify, MicroEsim, Yesim, Truely, FairPlay, Airhub, and Orange Travel offer plans with no hard data cap. Some of these plans advertise 5 G connectivity, although a few (for example Firsty) also specify a speed limit of 256 kbps and mention that speeds may be throttled. Other providers note a possible 5 Mbps speed limit before throttling would apply. Prices for these unlimited plans range from free to roughly $38 USD, with typical validity windows from one to twenty days, depending on the provider. Travelers should review each plan’s terms to understand any potential speed restrictions or tethering limits 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 provide a phone number and SMS support for Slovakia are available. Providers such as GlobaleSIM, Roamify, Orange Travel, and SimOptions offer inbound and outbound voice calls together with inbound/outbound SMS, and cover a wide range of data caps and validity periods from a few gigabytes and a week to several hundred gigabytes and a few months, with prices starting around $4 and climbing to roughly $120.

All of these plans use foreign dialing codes – +1 for the United States, +33 for France, +44 for the United Kingdom, and +420 for the Czech Republic – rather than Slovakia’s own +421 code. Thus the number you receive will appear foreign, which works for calls and text messages while abroad, but it is not a genuine Slovak local number. If you require a local Slovak number, you may need to look into other options such as data‑only eSIMs or VoIP services that can be used over the local network.
