Is signal good in Český Krumlov's old town?

Yes — the historic centre has solid 4G and 5G despite the medieval layout. You can stream, share photos from the castle terraces and use maps to weave through the lanes without trouble.

Can I use the same eSIM if I cross into Austria?

No. This is a Czech-only plan and won't roam in Austria. Near Lipno or the border your phone may briefly latch onto Austrian networks, so keep an eye on which country you're actually in.

Good to know in South Bohemia

Šumava's forests and gorges are a real coverage blackspot, so before any hike download offline maps and your route — and tell someone your plan, as data can vanish for hours on the trail.

Best time to visit South Bohemia

May to September brings warm days for lake swimming and forest hikes; December turns Český Krumlov into a fairytale Christmas-market scene.

Two simple ways to buy

South Bohemia eSIM plans: unlimited, or by the GB.

Every South Bohemia eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in South Bohemia — 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.

South Bohemia eSIM: your local data guide.

South Bohemia is castle-and-carp country: the UNESCO maze of Český Krumlov, the neo-Gothic Hluboká chateau, and Třeboň's medieval fishponds. Venture into the Šumava forests or along Lipno lake and you'll rely on data for trail maps and bus times. A South Bohemia eSIM keeps you oriented from Budweis breweries to the Austrian border.

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

Across the region

Where you'll lean on data in South Bohemia.

Český Krumlov

Strong 4G/5G blankets the old town, so you can navigate the twisting lanes and book castle-tower slots on the move.

Šumava National Park

Signal fades fast among the deep forests and peat bogs — download offline trail maps before hiking to Boubín or the Vydra valley.

Třeboň

Reliable data around the spa town and its fishpond dykes for planning cycle routes and carp-pond walks.

Lipno Lake

Good coverage across the resort shoreline, thinning on the far forested banks toward the Austrian frontier.

The practical bit

Getting around South Bohemia on your eSIM.

Apps you'll want online in South Bohemia

IDOS— Nationwide timetables for the trains and buses linking Budweis, Krumlov and the Šumava villages.
RegioJet— Popular private carrier with cheap coaches and trains from Prague and Vienna into South Bohemia.
Liftago— Czech ride-hailing that reaches smaller South Bohemian towns where Bolt and Uber rarely operate.

How long to stay in South Bohemia

Travellers usually give South Bohemia two to four days — a night or two in Český Krumlov plus time for Hluboká, Třeboň and a Šumava foray.

How much data for South Bohemia

A balanced 3-5 GB plan fits most trips, covering navigation and photo sharing; add more only if you'll hotspot a laptop from a lakeside cabin at Lipno.

Coverage in South Bohemia

Town coverage in České Budějovice and Český Krumlov is strong, but the Šumava mountains, deep forests and remote fishpond tracks are the region's real dead zones — plan for offline stretches there.
