The catalog has no plan whose name is Schengen. Europe is several regional products with different coverage, not one list under different titles. Open the destination list and look at the entries whose names mention Europe. The page named Europe, with no country count in the name, is Europe. The ones with a count in the name are separate products, and each page's own list still decides coverage.
Do not treat the number in the name as the list
Some names include a country count. That count is the supplier's own label, and it does not always match the list on the page. Choose from the countries under "Local networks" on the destination page. That list comes from plan data. This article does not write the countries out.
Match the list to your trip
1List the countries on this trip
Include places where you will land and need data. Start from your route, not from the longest product name.
2Open each candidate destination
Expand "Local networks" and check that every country is there. One missing country means that stop is not covered.
3Then read allowance and validity
Once coverage matches, allowance and validity are whatever that page lists. Choosing a format is separate. See eSIM, physical SIM, or pocket Wi-Fi.
