WestESIM plans are precisely geo-targeted to ensure optimal performance within their specified coverage areas. A plan purchased for the United States will provide robust connectivity exclusively within the US mainland and its territories. It will not extend to neighboring regions such as Mexico, Canada, or popular Caribbean destinations like Puerto Rico (unless specifically included). For travelers venturing across multiple countries, we highly recommend our regional eSIM packages, such as the 'Americas' plan, designed for seamless travel across diverse destinations from New York to Cancun, providing consistent high-speed data without interruption.
