Is San Marino typically included in standard 'Europe' or 'UK' roaming plans from my home carrier?

Generally, San Marino is not part of standard 'Europe' or 'UK' roaming bundles offered by most international carriers, particularly those from the USA, UK, or Canada. Since it's not an EU member, it's often categorized alongside other non-EU European microstates like Monaco or Switzerland, incurring premium roaming rates. WorldESIM simplifies this by offering global bundles that clearly outline multi-country coverage, ensuring you're connected from the heart of Europe to its charming enclaves without hidden fees.
