Do I Need an eSIM for Czech Republic?

Czech Republic has solid coverage from O2, T-Mobile CZ, and Vodafone CZ. But as a visitor:

• Non-EU roaming is expensive — $8-15/day from most carriers
• Local prepaid SIMs require ID and a trip to a store
• Prague trips are often short (3-5 days) — buying a local SIM isn't worth the effort

An eSIM is ideal for Czech Republic visits. Many plans include EU-wide coverage, perfect if you're combining Prague with Vienna, Berlin, or Krakow.
