PikaSim does not maintain an unlimited‑data eSIM for Montserrat; all of its plans for the island feature a hard data cap. The available options include fixed data bundles such as the Montserrat 20GB 30Days plan or the Montserrat 10GB 30Days plan, each offering a specific data allowance that must be used within 30 days. Because these caps are fixed, a customer can evaluate whether a larger bundle—like the 20GB plan—fits their usage needs. Choosing a fixed data plan can often be more cost‑effective, except for travelers who require an exceptionally high volume of data beyond the caps offered.
