Will I have signal on the Balaton ferries?

Close to shore, yes; mid-lake it can weaken. Download the BAHART ferry schedule and your route beforehand so a brief dip between Tihany and the southern shore doesn't catch you out.

Is data reliable up in the Bakony hills?

In the villages and along the main roads, generally yes. On the forest trails and in the quieter valleys it thins, so save offline maps if you're hiking or visiting the region's remoter castles and caves.

Good to know in Central Transdanubia

Balaton ferries between the northern and southern shores can lose signal mid-lake; grab the BAHART timetable and your offline map before you sail, and note beach Wi-Fi is often slower than your own eSIM data in peak season.

Best time to visit Central Transdanubia

June to September is peak Balaton season for swimming, sailing and lakeside festivals, while spring and early autumn are quieter for the wine roads and Bakony hikes.
