Does SouthESIM work when I'm just passing through Antigua on my way to Montserrat?

Our specific Montserrat SouthESIM plan is designed for connectivity within Montserrat itself. Since most travelers arrive in Montserrat via Antigua, you'll want to consider your connection strategy for both islands. If you need data as soon as you land in Antigua to arrange transport or check messages, we recommend checking out our Caribbean multi-country bundles. These bundles offer seamless data across various islands, ensuring you stay connected from the moment your adventure begins, no matter where you land first!
