While Montserrat is a British Overseas Territory, it's a common misconception that UK SIM cards offer free roaming there. Most UK and European carriers classify Montserrat as an 'International Zone,' leading to very high roaming charges. Relying on your home SIM could result in significant, unexpected bills. Truly Roaming provides a cost-effective and transparent data-only eSIM, ensuring you have reliable connectivity for your remote work and personal needs without the financial surprises of international roaming fees.
