eSIM Travel Tips for Hungary
Budapest ruin bars and navigation
The ruin bars of Budapest's Jewish District (Romkerts) are hidden in crumbling courtyards and old buildings. They are genuinely difficult to find without Google Maps. Having HelloRoam data running keeps you oriented in the maze of inner city Budapest streets.
Thermal baths and offline booking
Budapest's famous thermal baths including Szechenyi, Gellert, and Rudas need timed entry tickets, particularly in peak season. Book online before visiting and download your booking confirmation offline in case signal drops near the bathhouse entrances.
Lake Balaton day trips
Lake Balaton is Central Europe's largest lake and a popular day trip from Budapest. Train and bus services connect Budapest to the lake shore towns. Coverage is solid throughout the Lake Balaton region.
Budapest as a Central Europe hub

Hungary's affordability
Hungary is one of Europe's most affordable destinations for Australians. Excellent food, wine, and accommodation at much lower prices than Western Europe. Having data keeps you finding the local restaurants and wine bars rather than the tourist-priced strip.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.
