CoreESIM's Guyana-specific plan is provisioned for network access exclusively within Guyana's national borders. Travelers undertaking overland journeys from Suriname (e.g., via the ferry) or Brazil (e.g., at Lethem) will experience a cessation of data service upon crossing into these adjacent territories. For multi-country itineraries, CoreESIM recommends securing a regional eSIM or individual country-specific plans to ensure continuous data connectivity across borders.
