Many people see Slovakia as a weekend in Bratislava on the way from Vienna or Budapest. The ones who stay give it two weeks: the High Tatras, the Slovak Paradise gorges, Spis Castle and Kosice. For 15 days of unlimited, Airalo asks $48, Saily $48.99 and Holafly $50.50. Ubigi gives 30 GB at full speed for 15 days at $36. For a month, $69 to $73.90, or $49 for Ubigi's 60 GB, and Nomad sells no 15-day or 30-day unlimited here at all. Ringo Light charges $12.99 for 2 weeks and $21.99 for 30 days, one payment each, nothing renews.
Read what unlimited means before you pick. Airalo gives 3 GB a day at full speed, then 1 Mbps. Saily gives 5 GB a day, Nomad 2 GB. Ubigi gives a fixed amount, then 2 Mbps. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Ringo Light has no speed cap: the 2 weeks starts with 10 GB and the 30 days with 20 GB, and when you have used 80% we add 10 GB once and charge the $12.99 top-up. A heavy two weeks with us costs $25.98, under Ubigi's $36 for 15 days. A heavy month costs $34.98, under Ubigi's $49 and half of Airalo's month.
For a short trip, Ringo Light sells no 3-day or 7-day plan. Nomad sells 3 days of unlimited at $11 and a week at $25, and Ubigi a week with 20 GB at full speed for $24. Our 2 weeks at $12.99 still costs less than any rival's week.
Slovakia has four networks: Orange, Slovak Telekom, O2 and 4ka. Orange, Telekom and O2 cover Bratislava, Kosice, the other towns and the main roads and rail lines well, with 5G in the cities. Coverage thins in the mountains and deep valleys: Holafly names the High Tatras, the Low Tatras, the Slovak Paradise and the Slovak Karst on its own page. Every travel eSIM here that names its network rides Orange, O2 or both. None of the six names Telekom.
Slovakia uses the euro, and cards and phone wallets work almost everywhere in the towns; carry a little cash for mountain huts and village shops. A Slovakia plan stops at the border, and Vienna is an hour from Bratislava. For a trip that goes on to Austria, Czechia, Hungary or Poland, a Europe plan is the better buy: see our Europe comparison at /blog/best-esim-for-europe.
Ubigi, $10 for 10 GB. The cheapest 10 GB, and 25 GB for $19, the cheapest bucket around 20 GB. On O2 and Orange with 5G, installed by QR code, no app needed.
Nomad, $16 for 10 GB. 20 GB for $20 on O2 and Orange.
Airalo, $16 for 10 GB. Its Dobry den plan, 20 GB for $24, buckets from $4 for 1 GB. The app is needed.
Saily, $18.99 for 10 GB. 20 GB at $29.99. Its listing is from June; saily.com would not load for us.
Ringo Light, no buckets. Our 2 weeks starts with 10 GB for $12.99 and our 30 days with 20 GB for $21.99. For 10 GB that lasts a month, Ubigi at $10 is the better buy, and for about 20 GB, Ubigi's 25 GB at $19 or Nomad's 20 GB at $20 both cost less than our 30 days. Buy Ringo Light for unlimited, not for a bucket. We would rather you read that here than at checkout.
Ringo Light is our own data eSIM, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For Slovakia it sells two trips, both unlimited data at full speed with no speed cap: 2 weeks at $12.99, starting with 10 GB, and 30 days at $21.99, starting with 20 GB. Each adds 10 GB once at 80%, charged at $12.99. One payment, nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
The card to buy it is just below this article.
A weekend in Bratislava. Nomad unlimited, 3 days, $11. Ringo Light sells no 3 days; its 2 weeks is $12.99 if the trip might run longer.
Two weeks from Bratislava to the Tatras and Kosice. Ringo Light unlimited, 2 weeks, $12.99, less than any rival charges for one week.

You need your own number to keep ringing. None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
What to do in Slovakia, and what your phone needs for it. Eight places most first trips include, from Bratislava and the Danube to the High Tatras, Spis and Kosice in the east, with the one thing your data does for you at each. The towns all have good 4G and 5G; the mountains and gorges do not always.
Bratislava Castle, Bratislava. The white castle with four corner towers stands on a hill above the Danube, with St Martin's Cathedral and the Old Town below it. Walk up at sunset for the view over the river and the UFO bridge. Buy tram and bus tickets in the IDS BK app; ride-hailing apps such as Bolt also work in the city.
Devin Castle, Devin, west of Bratislava. A castle ruin on a rock where the Morava river meets the Danube, on the border with Austria. City bus 29 runs out from the centre in about half an hour. Austria is just across the river. If your phone picks up an Austrian network, a Slovakia plan stops, so keep it on a Slovak one.
Strbske Pleso, High Tatras. A glacial lake under the High Tatras peaks, reached by the electric mountain railway from Poprad. The high trails above the mountain huts close from 1 November to 15 June. Signal fades on the high trails. Download the offline map and save the mountain rescue number, 18300, before you set off.
Spis Castle, Spisske Podhradie. One of the largest castle ruins in Central Europe, spread across a limestone hill and listed by UNESCO. It sits between Poprad and Kosice, an easy stop on the way east. Buses to Spisske Podhradie are not frequent. Check the timetable on cp.sk before you go.
The gorges of the Slovak Paradise, Slovensky raj, near Hrabusice. Narrow gorges climbed on ladders, chains and footbridges over waterfalls, with Sucha Bela the classic first route. Many of the gorge trails are one way, uphill only. There is little signal inside the gorges. Load the trail map offline before you leave the car park.
Banska Stiavnica, Central Slovakia. An old silver mining town on steep hills, with an Old Castle, a New Castle and a town centre listed by UNESCO. Give it a full day, and a night if you can. The railway station is well below the old town. Your maps app shows the walk up or the local bus.
Bojnice Castle, Bojnice, near Prievidza. A fairytale castle of towers and spires, rebuilt around 1900 by Count Palffy, next to the oldest zoo in Slovakia. The inside is seen on a guided tour. Check the next tour time online before you drive over, and pay by card at the gate.
St Elisabeth Cathedral, Kosice. The largest church in Slovakia stands on Hlavna, Kosice's long main street of cafes and old houses. Climb the tower for the view over the east of the country. The fast train from Bratislava takes about five hours. Buy the ticket and a seat in the ZSSK app the day before.
We priced Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for Slovakia on 28 September 2026, all on the same day, in US dollars. Each rival's price comes from its own website where it showed dollars, otherwise from an esimdb.com listing, and every source and its date is listed below. Ringo Light's prices come from the catalogue our checkout charges.
We compare the trips people actually book: a week, two weeks and a month of unlimited data, and a 10 GB bucket. We read each brand's fair use and speed rules and quote them as the brands state them. We did not run speed tests, so this page makes no speed claims for any brand.
Ringo Light is our own product. We put it in the table on the same terms as everyone else, and where a rival is the better buy the page says so.
Left out: Maya Mobile, we could not read its own prices for this country on the day, so it stays out rather than being guessed.

For two weeks or a month of unlimited data, Ringo Light: $12.99 for 2 weeks and $21.99 for 30 days on 28 September 2026, against $48 for 15 days and $69 for 30 days at Airalo. For 3 days, Nomad at $11. For 10 GB over 30 days, Ubigi at $10; for about 20 GB, Ubigi's 25 GB at $19.
Holafly lists Orange and O2, Nomad and Ubigi O2 and Orange, and Airalo rides Orange with one other. Saily does not name its network on its listing. None of the six names Slovak Telekom or 4ka. Orange and O2 both cover the cities and main routes well.
Every brand has a limit somewhere. Airalo slows you after 3 GB a day, Saily after 5 GB, Nomad after 2 GB, Ubigi after its fixed full-speed amount. Holafly states no daily cap for your own phone. Ringo Light has no speed cap: it starts with 10 or 20 GB and adds 10 GB once at 80%, charged.
If your home plan is from an EU country, roaming in Slovakia is usually included at home prices, within a fair use limit. Travellers from the US, the UK, Canada or Australia usually pay a daily roaming fee, and that is where a travel eSIM saves money.
