MobileSIM eSIM Data Plans for Montserrat

MobileSIM does not provide a truly unlimited high‑speed eSIM plan for travelers to Montserrat. The only plan with “Unlimited” in its name is the 7‑day “Unlimited data for 7 days” plan, which actually gives 3GB per day of high‑speed data before the speed drops to a reduced rate of 1000kbps. After the 3GB daily allowance is reached, all data continues to work but at slower speeds.

Instead, MobileSIM offers several fixed‑data options. For example, the Global 20GB plan provides 20GB of high‑speed data for 30 days, and the Global 10GB and Global 5GB plans provide 10GB and 5GB respectively for the same period. These fixed‑data plans are often more economical than a truly unlimited offering for most travelers.

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.
