Does one eSIM cover both shores and the whole lake?

Yes. This is a single national Hungary plan, so the same eSIM works right around Balaton - Siófok, Balatonfüred, Keszthely, Tihany and Hévíz - and everywhere in between. There is no need for a separate SIM per town.

Will I get signal out on the ferries and beaches?

Coverage in the lakeside towns and on the beaches is generally solid, especially in summer. On the ferries you stay connected near shore but signal can wobble mid-lake, so download your onward directions before you sail.

Good to know in Lake Balaton

The lake's own Hévíz-Balaton Airport (SOB) at Sármellék only sees seasonal charters, so most travellers fly into Budapest and take the Balaton railway or drive; keep your eSIM on for live train times.

Two simple ways to buy

Lake Balaton eSIM plans: unlimited, or by the GB.

Every Lake Balaton eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Lake Balaton — you can always top up or switch on your next trip.

Traveller streaming and browsing freely on an unlimited-data travel eSIM

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

Lake Balaton eSIM: your local data guide.

Central Europe's largest lake stretches nearly 80 kilometres, so a Balaton holiday means constant maps - hopping the Szántód-Tihany ferry, tracking wine cellars up in Badacsony or finding the next beach club in Siófok. A Lake Balaton eSIM keeps ferry timetables, Bolt and restaurant bookings live whether you are on the party south shore or the calmer, spa-town north.

One eSIM for Lake Balaton and all of Hungary. It's the national Hungary eSIM — from $2.15/day with unlimited data, working the same in Lake Balaton as it does the moment you leave it.

The practical bit

Getting around Lake Balaton on your eSIM.

Apps you'll want online in Lake Balaton

MÁV— Hungarian Railways app; the Balaton line hugs both shores for tickets and times.
BAHART— Balaton's ferry company; schedules and tickets for the Szántód-Tihany crossing and boat trips.

How long to stay in Lake Balaton

Balaton is usually a three-to-five-day summer escape, long enough to try both shores, a ferry crossing, a spa town and an afternoon of hillside wine tasting.

How much data for Lake Balaton

A relaxed lake break leans on maps, ferry apps and photo sharing, so 3-5 GB usually suffices; pick Unlimited if you will stream by the water or hotspot from a lakeside apartment.

Coverage in Lake Balaton

Magyar Telekom, Yettel and One Hungary cover the resort towns and beaches well, with 5G in bigger centres like Siófok and Keszthely; signal thins in the Tihany and Badacsony hills and mid-lake.
