Top 10 eSIM providers for Budapest in 2026
Airalo takes the top spot for Budapest eSIM in 2026, combining reliable coverage on Magyar Telekom's network with per-GB pricing from around €1.50 and instant QR activation. The tie-breaker is consistent signal strength inside the M2 and M3 metro tunnels under Pest, where several competitors drop to Edge or lose connection entirely.
The scoring weighs three factors. Network coverage matters most in Budapest because the city's geography splits across hills on the Buda side and flat terrain on the Pest side, and the underground metro system (especially the deep-bore M3 line from Újpest-Központ to Kőbánya-Kispest) is where weak eSIM providers fail first. Per-GB cost comes second, with most travellers burning 1-2 GB per day between maps, translation apps, and uploading photos from Fisherman's Bastion or the ruin bars along Kazinczy utca in Erzsébetváros. Activation ease rounds out the picture at Budapest Liszt Ferenc Airport (BUD), where you'll want data the moment you clear Terminal 2A, not 30 minutes later wrestling with an app download on patchy airport Wi-Fi.
The most common mistake visitors make is buying an eSIM that routes only through Yettel. Yettel covers Pest's flat districts well enough, but signal drops sharply around the Castle District on the Buda side and inside the thick-walled thermal bath complexes at Széchenyi and Gellért, where the humid stone corridors seem to swallow radio waves. Magyar Telekom tends to hold up better in those spots. Another frequent error is purchasing a plan denominated in megabytes rather than gigabytes. Some providers still sell 500 MB packages for what looks like a fair price, but a single afternoon of tram navigation between Széll Kálmán tér and Móricz Zsigmond körtér on Google Maps can eat through that allowance in hours. Mind you, the M4 metro line has better underground coverage than M3, so your experience varies by route.
Airalo is not the right pick for everyone. If you're staying longer than 14 days, Holafly's unlimited-data Europe plan likely works out cheaper per day, especially for remote workers camped in the co-working cafés around Újlipótváros on Pozsonyi út. And if you need a local Hungarian phone number for booking restaurants or communicating with apartment hosts through Viber, none of the eSIM-only providers on this list will help. In that case, picking up a physical Telekom SIM at the Telekom shop near Deák Ferenc tér, the transfer point where the M1, M2, and M3 lines converge, still makes more sense. Worth noting, too, that the M1 (the Földalatti, continental Europe's oldest metro) runs so shallow beneath Andrássy út that eSIM coverage is rarely an issue on that line.

Visit Airalo -
Holafly
Unlimited data on a Europe-wide plan routed through Vodafone Hungary. A strong pick for remote workers pulling long sessions in the Újlipótváros cafés along Pozsonyi út, where streaming and video calls need consistent bandwidth over days rather than gigabyte rationing.
-
Saily (by Nord Security)
Bundles a VPN at no extra charge. Coverage on Yettel's network holds steady across Pest's District VII and District VIII ruin-bar quarter, though signal can thin near the Citadella on Gellért Hill. The 5 GB Hungary plan runs about €6.
-
Nomad eSIM
Offers a Hungary-only plan at roughly €1.30 per GB, the cheapest rate on this list. Routes through Magyar Telekom. Tested well around Keleti pályaudvar and the Great Market Hall area in Ferencváros, though the app interface feels dated compared to Airalo's.
-
Maya Mobile
Regional Europe plan with solid coverage across both the Buda hills and flat Pest side. Tested well around the Széchenyi Thermal Bath area and Margaret Island. Pricing sits mid-range at about €2 per GB, with a clean app and QR activation.
-
Ubigi
Partners with Orange roaming agreements that route to Vodafone Hungary locally. The 10 GB Europe plan costs around €16 and lasts 30 days. Signal holds along the Danube promenade from the Shoes on the Danube Bank memorial down to the A38 ship near Petőfi Bridge.
-
Alosim
Lean app with QR-only setup, no account creation needed. Their 3 GB Hungary plan costs about €5 and routes through Yettel. Coverage is fine in flat Pest districts but turns patchy in the Buda hills above Széll Kálmán tér and inside the Castle District labyrinth tunnels.
-
Yesim
Swiss-based provider with a Europe plan at roughly €1.80 per GB. Coverage relies on Vodafone Hungary. Performs well in the Belváros shopping district around Váci utca and Vörösmarty tér, though some users report throttling after 5 GB on the cheaper tiers.
-
Discover+ (eSIM Go)
Straightforward 1 GB, 3 GB, and 10 GB tiers for Hungary specifically, using Magyar Telekom infrastructure. The 10 GB plan at about €12 suits a week-long stay with moderate use. QR activation with no app required, helpful if BUD airport Wi-Fi is running slow on arrival day.
-
Instabridge eSIM
Started as a Wi-Fi sharing app and now offers eSIM data. Their 5 GB Europe plan costs around €8. Coverage maps to Yettel, which is fine in the Erzsébetváros ruin-bar district and along the M4 metro from Keleti to Kelenföld, but weaker underground on the older M3 line.
