CoreESIM's French Guiana plan is geo-restricted for network access exclusively within French Guiana. Any attempt to connect from neighboring countries like Suriname (e.g., after crossing the Maroni River to Albina) or Brazil (e.g., via the Oyapock River Bridge to Oiapoque) will result in a loss of data service. For seamless regional travel, CoreESIM recommends a multi-country Latin America eSIM or separate country-specific plans to maintain continuous connectivity across borders.
