The eSIM I purchased worked pretty much everywhere in Germany and Czechia. Even streamed Netflix on it. Great price $25 for 50 Gigs. I almost took off a star because the printed instructions had the wrong activation link and I had to get on the chat with them - they then resolved the issue quickly by sending the correct activation link.
