No, Airalo does not provide Montserrat eSIM plans that include a phone number or SMS capability. The only options available from Airalo for Montserrat are data‑only plans. Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm in advance that these services are accessible in Montserrat, as some destinations may block or restrict certain apps.
