You do not get a new phone number with this eSIM.
Setting up your eSIM? The installation and activation guide walks through it step by step, and the full FAQ covers device compatibility, hotspot, dual SIM and topping up.
One plan covers the whole country, so the same eSIM works in Budapest and out at Lake Balaton and the wine regions. Install it before you travel, switch off airplane mode on arrival, and you are online for the baths, the ruin bars and the maps in between.
The eSIM connects automatically when you turn off airplane mode at Budapest (BUD), the country’s main gateway. Your 100E airport bus, ride app and maps are ready the moment you land.
Hungary's networks - Magyar Telekom, Yettel and One - give strong 4G/LTE nationwide with fast 5G across Budapest and the bigger cities. Coverage is reliable around Lake Balaton, the wine regions and the main roads, thinning only in remote rural pockets.
The same eSIM works across Budapest - the thermal baths, the Buda Castle district and the Danube embankments - and on day trips out to the Danube Bend towns of Szentendre and Esztergom, or down to Lake Balaton for the summer. You stay online on the trains and main routes throughout.
Yes. 5G is widely available across Budapest and the larger cities, with strong 4G/LTE elsewhere - plenty for maps, streaming and video calls.
Yes. Coverage is reliable around Lake Balaton, the Danube Bend towns and the wine regions, so booking apps and maps work throughout your day trips.
Yes. You will have data across the city for live maps and transit apps; signal can briefly dip in the deepest metro tunnels and reconnects automatically.
