ZenSim eSIM Data Plans for Montserrat

ZenSim does not provide a truly unlimited high‑speed eSIM for Montserrat. The plans that carry “Unlimited” in the name give 3GB of high‑speed data per day for a five‑day period; after that limit is reached, the speed is throttled. If a traveler needs a larger amount of data without the daily cap, ZenSim offers fixed‑data options such as the 20GB plan valid for 15 days (priced at $66.00 USD) or the 20GB plan valid for 30 days (priced at $75.00 USD), as well as a 10GB plan for 15 days (priced at $42.00 USD). These fixed plans can be more economical for many users, especially those who use more than 3GB per day or need coverage beyond the 5‑day window.

ZenSim does not provide an eSIM plan for Montserrat that includes a phone number or SMS capability. Customers can only access data‑only plans for the island. For voice and messaging services, travellers can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send texts.

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.
