Is this CoreESIM Austria plan valid for adjacent countries like Germany or Switzerland?

This particular CoreESIM data plan is exclusively designated for use within Austria. Should your travel extend into neighboring territories such as Germany or Italy (both EU), or non-EU countries like Switzerland, your data connectivity will cease at the border. For seamless multi-country European itineraries, CoreESIM provides regional European eSIM options that encompass a broader geographic scope, ensuring uninterrupted service across multiple nations without the need for multiple eSIMs.
