Can I livestream Poznań's noon goats?

Yes. The Stary Rynek has strong data, so you can film or livestream the mechanical billy goats butting heads on the town hall clock at midday without buffering.

Is Poznań well connected by train?

Very. It's a key junction on the Berlin-Warsaw line with frequent fast and regional services. Use Koleo with your data on to compare options and prices before boarding your train.

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.
