Does the eSIM work up in the Beskydy mountains?

In the valley towns and resorts, yes. On the higher trails to Lysá hora, Radhošť or Pustevny signal genuinely thins, so download offline maps before you climb.

Am I at risk of Polish or Slovak roaming here?

Near the borders and on the ridgetops, yes — phones can latch onto Polish or Slovak masts. This Czech plan won't work there, so lock to a Czech operator if data stops on high ground.

Good to know in Moravian-Silesia

The Beskydy and Jeseníky ridges are the region's coverage weak spots, and you're close to both the Polish and Slovak borders — near Bílá or the Lysá hora summit your phone may grab a foreign network, so verify it before using data.

Best time to visit Moravian-Silesia

June to September suits Beskydy hiking and the July Colours of Ostrava festival, while winter opens the ski slopes at Pustevny and Bílá.
