Is this CoreESIM plan valid for use in the U.S. Virgin Islands (USVI), specifically St. Thomas or St. John?

This particular CoreESIM data plan is geographically restricted to the British Virgin Islands (BVI) territory. It does not extend coverage to the U.S. Virgin Islands (USVI), which includes islands such as St. Thomas, St. John, and St. Croix. These are distinct sovereign entities with separate telecommunications jurisdictions. Transitioning from Tortola (BVI) to any USVI island would result in a loss of CoreESIM service and potential commencement of international roaming charges from your primary SIM provider.
