CoreESIM's USA-specific data plans are provisioned exclusively for operation within the geographic boundaries of the United States. Connectivity is not extended to Canada or Mexico. For users whose itineraries include cross-border travel, such as visiting Niagara Falls (Canada) from the US side or traveling to Cancun (Mexico), the USA eSIM will cease to provide service. CoreESIM offers dedicated North American regional plans designed to provide seamless connectivity across all three countries, integrating various MNOs for comprehensive coverage.
