Will I have data at the Jasna Góra monastery in Częstochowa?

Yes, coverage around the monastery is good, so you can check Mass times and Black Madonna viewing hours - especially useful during the August pilgrimages, when crowds swell dramatically.

Can I stream while hiking in the Beskid mountains?

In resort towns like Szczyrk and Wisła, yes. Higher up toward Skrzyczne the signal thins, so download maps and any offline content before heading onto the trails to be safe.

Good to know in Silesia

Silesia's cities blur into one continuous urban area, so a single ZTM ticket bought in the app covers trams and buses across Katowice, Gliwice and beyond - handy when town borders are invisible.

Best time to visit Silesia

May to September suits city visits and Beskid hiking; winter brings skiing to Szczyrk and Wisła, and August fills Częstochowa with pilgrims.

Two simple ways to buy

Silesia eSIM plans: unlimited, or by the GB.

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

Silesia eSIM: your local data guide.

Silesia has swapped its coal-mine image for revamped Katowice galleries, the pilgrimage monastery at Częstochowa and the green Beskid ranges to the south. A Silesia eSIM keeps you navigating the sprawling GZM metro area, timing visits to the Jasna Góra icon and following mountain trails above Wisła and Szczyrk.

One eSIM for Silesia and all of Poland. It's the national Poland eSIM — from $2.35/day with unlimited data, working the same in Silesia as it does the moment you leave it.

Landing at Katowice - Pyrzowice (KTW)?

Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.
