eSIM.sm offers an eSIM for use in Montserrat, but it is a dataโonly plan and does not provide a local phone number or SMS capability. Travelers can connect to internet services on 4G or 5G networks in the island nation but cannot receive or make voice calls or text messages through a traditional local number.
Because the plan lacks phone number functionality, users are encouraged to use internetโbased messaging and calling apps such as WhatsApp, Telegram, or iMessage to communicate. These VoIP services work over the data connection provided by the eSIM and allow calls and messaging without a phone number or SMS.
