Does a CoreESIM plan designated for Germany extend its validity to neighboring countries like <strong>France</strong>, <strong>Austria</strong> (EU), or <strong>Switzerland</strong> (non-EU)?

A CoreESIM plan specifically configured for Germany is generally valid only within Germany, or within the broader EU/EEA zone if it is a regional European plan. If your itinerary includes travel to adjacent EU countries such as France or Austria, a regional EU plan would typically provide continuous service. However, for non-EU nations like Switzerland, your data connectivity will cease upon crossing the border unless the eSIM plan explicitly includes it. For such diverse European travel, CoreESIM advises selecting a multi-country European regional eSIM that covers all intended destinations.
