Is there mobile signal at Karlštejn and Konopiště castles?

The towns and car parks have good 4G, but signal softens on the forested approaches and inside thick castle walls. Download maps and tickets before you set off to be safe.

Can I stream on the train between Prague and Kutná Hora?

Generally yes on this busy corridor, where 4G/5G is strong. Expect brief dips in cuttings and tunnels, so cache podcasts or playlists for a smoother ride.

The practical bit

Getting around Central Bohemia on your eSIM.

Apps you'll want online in Central Bohemia

PID Lítačka— Prague's integrated transport app, valid on many suburban trains and buses reaching into Central Bohemia.
IDOS— The go-to national timetable app for planning any Czech train or bus connection door to door.
Liftago— Czech home-grown ride-hailing, handy for towns where Uber and Bolt are thin on the ground.
Můj vlak— České dráhy's own app for buying regional rail tickets and checking live platform updates.

How long to stay in Central Bohemia

Most visitors base themselves in Prague and dip into Central Bohemia on single-day excursions, so plan two or three separate day trips rather than overnight stays.

How much data for Central Bohemia

Since you're mostly doing day trips from a Prague hotel with Wi-Fi, a balanced 3-5 GB plan comfortably covers maps, ticket apps and photo uploads across a week of excursions.

Coverage in Central Bohemia

Coverage is genuinely strong in Kutná Hora, Kladno and other towns and along the main rail lines, but expect thinner signal in the wooded hills around Karlštejn and inside castle interiors.
