Is this CoreESIM plan valid if I travel to neighboring countries like Peru or Ecuador from Colombia?

This CoreESIM plan is exclusively provisioned for network access within Colombia. If your travel plans extend to neighboring countries such as Ecuador or Peru, for example, crossing the border near Ipiales, your data service will cease upon entry into the new country. For travelers undertaking multi-country itineraries across South America, CoreESIM recommends a regional LATAM plan or separate country-specific eSIMs to ensure continuous connectivity.
