Can I expect free roaming in Switzerland with my existing EU, UK, or US SIM card?

It's a frequent misunderstanding, but free roaming with your existing EU, UK, or US SIM card is generally not available in Switzerland. Despite its central European location and inclusion in the Schengen Area, Switzerland is not part of the European Union. Consequently, the EU's 'Roam Like at Home' policy does not apply. Most international carriers, including those from the EU and UK like Vodafone or O2, will impose international roaming charges.
