The short answer
The trip is two Danube capitals and one border crossing, Budapest to Vienna by train or boat, and I priced the Europe plans that cover both on 25 October 2026. The one I would buy is Ringo Light: $22.99 for 2 weeks or $35.99 for 30 days of unlimited data at full speed, one install for both. For 3 days Airalo is cheapest at $11.50, and for a 10 GB bucket Ubigi at $15.
One eSIM from Budapest to Vienna and the Alps: unlimited data at full speed for 2 weeks at $22.99 or 30 days at $35.99, nothing renews. Airalo Eurolink asks $49 for 15 days and $71 for the month.
10 GB for 30 days at $15, valid across 38 countries. Its 15 days is 30 GB at full speed, then 2 Mbps, for $35.
Eurolink covers 41 countries, with Hungary and Austria among them. 3 days of unlimited at $11.50, 5 GB a day at full speed.
Days, not gigabytes, in 33 countries. No daily cap stated for your own phone; sharing limited to 1 GB a day. $27.50 for a week.
Prices read on 25 October 2026: Airalo, Holafly, Saily, Nomad, Ubigi on their own sites or listings, Ringo Light from its catalogue. All in US dollars unless stated. Treat every number as a snapshot.

What to do in Hungary and Austria, and what your phone needs for it
Eight places that often fill a trip from Budapest to Vienna, Salzburg and Hallstatt, with the one thing your data does for you at each. One regional eSIM stays on across the border between them.
One plan for both countries: Ringo Light
Hungary and Austria meet at the Schengen border east of Vienna, where the train between Budapest and Vienna slips across without a stop. One Europe eSIM works on both sides, and you install it once at home. Two country eSIMs mean two installs, two bills and a switch of line somewhere near Hegyeshalom. On a trip that follows the Danube, one plan is the easier one.
The regional plan costs less too. Ringo Light's Europe trips are $22.99 for 2 weeks and $35.99 for 30 days, unlimited data at full speed. The rivals' regional unlimited costs more: $49 for 15 days on Airalo Eurolink, $49.99 on Saily and $51.50 on Holafly, and $71 to $76.50 for a month. Ubigi asks $35 for 15 days but slows to 2 Mbps after 30 GB.
Here is the sum I checked. Hungary's 2 weeks is $14.99 and Austria's $14.99 on their own pages, $29.98 together, against $22.99 for the Europe trip that covers both. For a month it is $26.99 and $26.99, $53.98 together, against $35.99. The country plans are for people who stay in one place.
Which plans cover both countries
Hungary and Austria are both EU members, so both sit in the core of the Europe lists. I could only confirm the wider lists from the Europe page I priced. Ringo Light covers 33 countries, the EU countries plus the UK, Switzerland, Norway, Iceland, Liechtenstein and Gibraltar, so both are in. Airalo Eurolink covers 41 countries, both in. Holafly lists 33 countries, Saily 35, Nomad 35 on its unlimited plans and Ubigi 38.
For Holafly, Saily, Nomad and Ubigi I could not confirm a country by country list on the day, so check that Hungary and Austria both appear at checkout. If you add Slovakia for a day in Bratislava, I would look for it by name too.
If you want a data bucket: Ubigi or Nomad
- Ubigi, $15 for 10 GB. The cheapest 10 GB for 30 days across 38 countries. 25 GB is $29, and a 20 GB monthly plan at $19 that renews until you cancel it.
- Nomad, $23 for 10 GB. And 20 GB for 30 days at $27, the cheapest one-off 20 GB here.
- Airalo, $31 for 10 GB. Eurolink 20 GB for 30 days is $48, and Eurolink covers the most countries.
- Saily, $35.99 for 10 GB. From saily.com, 25 October 2026.
- ✓Ringo Light, no buckets. If your trip is Hungary and Austria on light use, Ubigi's 10 GB at $15 is $7.99 under Ringo Light's 2 weeks, and Nomad's 20 GB at $27 is $8.99 under its 30 days. Buy Ringo Light for unlimited, not for a bucket. I would rather you read that here than at checkout.
What Ringo Light is
Ringo Light is the data eSIM Ringo sells to fund the full Ringo, one plan that works everywhere with your own number ported onto it. I write for Ringo, so weigh that. For Hungary and Austria it sells the Europe trip across 33 countries, unlimited data at full speed: 2 weeks at $22.99 and 30 days at $35.99. Nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app. On the train into Austria it moves to a local network on its own.
The card to buy it is further up this page, just after the side-by-side table.
Pick by trip
Ringo Light sells no 7-day plan, so I would take its 2 weeks at $22.99, which costs less than any rival's 7 days. For a long weekend in Budapest, Airalo Eurolink 3 days at $11.50.
Ringo Light unlimited, 2 weeks, $22.99. The whole trip on one eSIM, and less than the two country plans at $29.98.
Ringo Light unlimited, 30 days, $35.99. Ubigi at $62 if you want a fixed 60 GB.
Ubigi 10 GB for 30 days at $15, valid in both countries.
Check the country list at checkout before you pay. Serbia is outside Ringo Light's list, and I did not confirm Slovakia on every plan.
None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
