Will I get signal on Lake Constance ferries?

Generally yes near the shore and busy crossings like Konstanz to Meersburg, as you stay close to land. Mid-lake coverage can wobble, so download tickets and maps before you board.

Is data good enough for navigating Stuttgart's traffic?

Very much so - Stuttgart has excellent 5G, so live traffic, parking apps and the VVS transit planner all run smoothly whether you're driving or riding the S-Bahn.

Good to know in Baden-Württemberg

The Neckar and Rhine valleys keep strong signal, but the Swabian Alb's caves and the forest roads near the Bodensee can drop to 4G or less - cache your driving route before heading into the hills.

Best time to visit Baden-Württemberg

May to September offers warm days for Lake Constance and vineyard walks, while autumn paints the Neckar valley and wine festivals fill the calendar.

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.
