AeroSims eSIM Data Plans for Montserrat

AeroSims does not provide a genuine unlimited data eSIM for Montserrat. The plans that include “Unlimited” in their name actually offer 2GB of high‑speed data per day, after which the speed is reduced to 512kbps, so they are fixed data plans rather than true unlimited ones.

Instead, AeroSims sells fixed data plans such as Montserrat 20GB for 30 days and Montserrat 10GB for 30 days, which provide higher data allowances within a set validity period. These plans can be topped up while still valid, allowing travelers to add more data without reinstalling a new QR code. For most users, selecting one of these fixed data options is a more cost‑effective choice unless extremely heavy data usage is expected.

AeroSims does not provide an eSIM for Montserrat that includes a phone number or SMS capability. The provider only offers data‑only plans for this destination. Travelers who need voice or messaging can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that the apps they rely on are accessible in Montserrat before purchasing.

AeroSims offers 11 single‑country plans and 3 multi‑country plans that include Montserrat. The plans vary in price from about $13.23 to $358.40 and in data cap from 2 GB to 20 GB. Some plans provide a fixed data amount that is available for the entire validity period, while others impose a daily data cap that limits usage each day. This range gives travelers flexibility depending on how much data they need and how long they plan to stay.
