Do I need to adjust any settings on my HotelESIM when crossing international borders, for example, from Argentina to Brazil?

Not at all, your HotelESIM handles border crossings with remarkable ease. Whether you're traveling overland between countries like Argentina and Brazil, or island-hopping in the Caribbean, your phone will automatically connect to the strongest local network partner. There's no need to manually change settings; just ensure 'Data Roaming' is enabled on your device for a seamless transition. This means more time enjoying your journey and less time fiddling with your phone.
