This particular CoreESIM data package is geo-restricted and provisioned exclusively for network access within Guatemala. For travelers navigating the Central American region, it is crucial to understand that this plan does not support international roaming into adjacent territories. Crossing into Mexico (e.g., from San Cristobal), Belize (e.g., from San Ignacio), or El Salvador (e.g., towards Santa Ana) will result in a loss of data connectivity. For multi-country itineraries, CoreESIM offers regional or global eSIMs designed for broader coverage.
