CoreESIM strongly recommends completing the eSIM installation and activation process prior to your departure for Montserrat, ideally while still in Antigua or your home country. This proactive approach ensures immediate network acquisition upon arrival, such as when disembarking the ferry at Little Bay. It circumvents potential connectivity challenges that might arise from unstable network conditions during transit or upon reaching the island, providing uninterrupted service from the outset.
