thirr.com eSIM Data Plans for Montserrat

Thirr.com does not currently provide an unlimited data eSIM plan for Montserrat. All available offerings are fixed‑data packages.

Travelers can choose from several sizable plans, such as the MS 50GB 365D plan, which grants 50GB of 4G data that remains valid for 365 days, or the MS 30GB 30D plan, offering 30GB of data for 30 days. These fixed plans can be more economical for most users, especially those who do not need an extremely high data allowance. Only if a traveler expects to use far more data than the largest fixed option, should they consider a more extensive plan or a different provider.

thirr.com does not provide Montserrat eSIMs that include a local phone number or SMS capability. The provider only sells data‑only eSIMs for Montserrat. Travelers can still use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging.

For Montserrat, thirr.com offers seven single‑country data plans and four multi‑country plans that include the island.
