MobileSIM eSIM Data Plans for Montserrat

MobileSIM does not provide a truly unlimited data eSIM for Montserrat. The plan called “Unlimited data for 7 days” actually delivers a 3GB per day allowance and reduces speed to 1000kbps after that limit, so it remains a fixed‑data plan rather than an unlimited one.

If a higher data capacity is needed, MobileSIM offers fixed data plans such as the Global 20 GB for 30 days, which supplies 20 GB of high‑speed data for 30 days, or the Global 10 GB for 30 days, which provides 10 GB for the same period. These plans allow more data than the smaller fixed deals and can be more cost‑effective for travelers who use a lot of data but still prefer a capped amount rather than an unlimited option.

MobileSIM does not provide Montserrat eSIM plans that include a local phone number or SMS capability. Only data‑only eSIM options are available for travelers heading to Montserrat.

With a data‑only plan, users can still make voice and messaging calls through popular VoIP applications such as WhatsApp, Telegram, and iMessage. However, some destinations may restrict certain VoIP services, so it is wise to confirm that the apps a traveler relies on are accessible in Montserrat before purchasing a plan.

MobileSIM provides four single‑country plans for Montserrat and ten multi‑country plans that include the island in their coverage. Prices for these plans range from $2.30 to $66.00, and data caps span from 200 MB to 20 GB, with validity periods between 5 and 60 days. The majority of the plans are fixed‑data‑cap schemes, while one plan offers a daily data‑cap option, which limits the amount of data available each day. Some daily‑cap plans include a reduced speed of 1000 Mbps.
