This specific CoreESIM data plan is provisioned exclusively for use within El Salvador. It is imperative for users traversing Central America to understand its geographical limitations. If your itinerary involves crossing land borders into adjacent countries such as Guatemala, Honduras, or Nicaragua, your data connectivity will cease. For example, traveling from San Salvador to Antigua, Guatemala, or onward to Tegucigalpa, Honduras, will require a separate regional eSIM or a distinct plan for each country to maintain continuous internet access.
