Stellar eSim does not provide a true unlimited high‑speed data plan for Montserrat. Each plan that carries “Unlimited” in its name actually has a hard cap of 1GB for Caribbean‑wide options or 2GB for Montserrat‑only plans, after which the speed would be throttled (the specific throttled speed is not listed in the data). If a traveler needs more data, the provider offers fixed‑data plans such as the Montserrat 20GB 20‑day or Montserrat 20GB 30‑day options, which give 20GB of high‑speed data for the stated validity period and are examples of the larger‑allowance alternatives.
