Does CoreESIM facilitate free roaming in Montserrat when using a UK-issued SIM card?

CoreESIM clarifies that while Montserrat is a British Overseas Territory, free roaming with a standard UK-issued SIM card is typically not the case. Most UK and European mobile network operators classify Montserrat as an 'International Zone,' incurring significant pay-as-you-go roaming charges. CoreESIM provides a dedicated data-only eSIM solution for Montserrat, offering a transparent and often more cost-effective alternative to avoid unexpected high roaming fees from your home carrier, ensuring predictable connectivity.
