JamboSim eSIM Data Plans for Montserrat

JamboSim’s eSIM called “Caribbean Unlimited / 7 Days” is technically not a true unlimited plan; it allows 3 GB of high‑speed data per day and thereafter the speed is reduced to 1000 kbps. Consequently, travelers to Montserrat who need unrestricted high‑speed data will find no unlimited option from JamboSim.

Instead, the provider offers several fixed‑data plans that cover Montserrat. For example, a 20 GB plan valid for 30 days costs $40.99 USD, and a 10 GB plan for the same period is priced at $25.99 USD. These plans remain available for Montserrat and can be more cost‑effective unless a user is an extremely heavy data consumer.

Yes, JamboSim offers eSIM plans that include a phone number and outbound SMS for travelers visiting Montserrat. These plans come in several options, with data caps ranging from 1 GB to 20 GB and validity periods from 7 days up to 365 days. The pricing for these plans starts at $11.99 USD for the 1 GB / 7‑day option and goes to $105.99 USD for the 20 GB / 365‑day option. All these plans use a dialing code of +1, which is the North American telephone code that includes Montserrat; users can make outbound voice calls and send outbound SMS, but inbound calls and SMS are not included. Travelers are advised to confirm the exact capabilities and any restrictions directly with JamboSim before purchasing.

JamboSim offers four single‑country data plans for Montserrat. There are no dedicated multi‑country plans that include Montserrat in their coverage list. The plans range in price from roughly $1.99 to $106.99 and provide data caps between 200 MB and 20 GB. Among the available options, most are fixed‑data quantities while a small subset uses daily data caps, giving travelers flexibility in how they consume data over the validity period.
