ZenSim eSIM Data Plans for Montserrat

ZenSim does not provide a true unlimited‑data eSIM for Montserrat. The plans listed for the country are fixed data bundles, such as 20 GB for 15 or 30 days, and a standard period plan that offers 3 GB per day and reduces speed to 1000 kbps after the daily limit. While a couple of plans have “Unlimited” in their name, the column values show a hard data cap, so the high‑speed data is limited and throttled once the cap is reached. Travelers looking for a more extensive data allowance may choose one of the 20 GB or larger bundles as a cost‑effective alternative.

ZenSim does not provide any Montserrat eSIM plans that include a phone number or SMS capability. The provider offers only data‑only plans for travelers heading to Montserrat.

Those looking to stay in touch can use internet‑based VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm that these applications are accessible in Montserrat before purchasing a plan.

ZenSim provides 10 single‑country plans and 10 multi‑country plans that include coverage in Montserrat. The plans range in price from about $10.00 to $84.00 and offer data capacities between 1 GB and 20 GB. Most of the offerings use a fixed data cap, while a smaller subset—just two plans—adopt a daily data cap structure, allowing a set amount of data to be used each day rather than a single pooled allocation. These plans also support tethering, giving users flexibility to share the data with other devices.
