thirr.com eSIM Data Plans for Montserrat

There are no unlimited data plans available from thirr.com for Montserrat.

Instead, thirr.com offers fixed‑data eSIMs that can be selected based on the amount of data you need. One example is a 50GB plan valid for 365 days, and another is a 30GB plan valid for 30 days. These fixed‑data options can be more cost effective for most travelers, except for users who consume very large amounts of data.

thirr.com does not provide Montserrat eSIM plans that include a local phone number or SMS capability. The provider offers only data‑only eSIMs for travel to Montserrat, so plans do not support inbound or outbound voice or text messaging.

If you need messaging or calling while in Montserrat, you can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection provided by the eSIM.

thirr.com lists seven single‑country data plans and five multi‑country data plans that include Montserrat. The plans range in price from about $4.60 to $230.68, with data caps between 1 GB and 50 GB and validity periods from 3 to 365 days. Single‑coverage options provide a fixed amount of data for the entire validity period, while multi‑coverage plans allow the same data to be used across several countries, giving travelers flexibility. Tethering is permitted on many of the plans.
