We strongly advise installing and activating your WestESIM before you depart for Montserrat, ideally while you still have a stable internet connection at home or in Antigua. This proactive approach guarantees immediate connectivity upon your arrival, whether you're landing at John A. Osborne Airport or disembarking a ferry at Little Bay. Having your WestESIM ready ensures you can promptly arrange transport, check important messages, or navigate without any delay.
