GulfData does not offer a Montserrat eSIM that includes a phone number or SMS capability; the plans available for Montserrat are strictly data‑only.
Travelers can still make calls and send messages using VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain apps or VoIP services, so it is advisable to verify that the applications needed for communication are accessible in Montserrat before purchasing a GulfData plan.
