Can I expect free roaming in non-EU countries with my existing European or UK SIM card?

It is crucial to understand that 'Roam Like at Home' benefits typically apply exclusively within the EU/EEA and certain UK domestic plans. For destinations outside this zone, such as Switzerland or Monaco, your existing EU or UK SIM card will almost certainly incur significant international roaming charges. WestESIM provides a cost-effective and transparent alternative, offering dedicated plans that ensure you avoid unexpected bills and maintain high-speed connectivity.
