Is roaming free in Switzerland with my EU/UK/US SIM card, or should I opt for EastESIM?

This is a frequent misunderstanding! Despite being centrally located in Europe, Switzerland is not part of the European Union. Therefore, the EU's 'Roam Like at Home' policy does not apply. If you're using a SIM from an EU, UK, or US carrier like Vodafone, O2, or T-Mobile, you will incur significant international roaming charges for data usage. EastESIM provides cost-effective, dedicated data plans for Switzerland, ensuring you can navigate Zurich or share photos from the Swiss Alps without unexpected expenses.
