Astaroam eSIM Data Plans for Montserrat

Astaroam does not provide an unlimited data eSIM for Montserrat. The provider’s plans for the island are fixed data bundles that expire after a set period. The largest bundles available are a 10 GB package valid for 30 days at $36.78 USD and a 5 GB package also valid for 30 days at $21.80 USD. These plans include tethering and, for the 10 GB variant, 5 G coverage. Choosing one of these fixed data plans can be more cost‑effective than purchasing a higher‑volume or Pay‑as‑you‑go option unless the traveler expects to consume a very large amount of data.

Astaroam does not provide a Montserrat eSIM that includes a local phone number or SMS capability. Only data‑only eSIMs are available from this provider. Travelers who need to make voice calls or send text messages can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Montserrat before purchasing a plan.

Astaroam offers 12 data plans for Montserrat in total, composed of 3 single‑country plans and 9 multi‑country plans. The plans span a price range from $6.21 to $54.58 and a data cap range of 1 GB to 10 GB, with validity periods lasting between 7 and 30 days. Most of the plans provide a fixed amount of data for the entire validity window, and tethering is allowed on some options.
