Astaroam eSIM Data Plans for Saint Martin

Astaroam does not provide a truly unlimited high‑speed data plan for Saint Martin. The plans that bear the “Unlimited” name are limited to 3 GB of high‑speed data per day. Once this daily quota is reached the connection speed is reduced to 1000 kbps, so the data is not truly unrestricted.

Instead, Astaroam offers fixed‑data eSIMs that may be a better value for most travelers. For example, a 10 GB plan for 30 days costs $36.13 USD, and a 5 GB plan for 30 days costs $21.42 USD. These plans provide a set amount of high‑speed data and do not impose a daily limit, making them a straightforward alternative for users who need predictable usage.

Astaroam does not provide an eSIM for Saint Martin that includes a local phone number or the ability to send or receive SMS messages. The provider only offers data‑only plans for that destination. Travelers who rely on voice or text services can use popular VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but they should verify that the specific apps they need are accessible in Saint Martin, as some services may be blocked or restricted.

Astaroam offers five single‑country data plans and ten multi‑country plans in Saint Martin. The plans span a price range from roughly $3.91 to $44.95 and a data cap range of 1 GB to 10 GB, with validity periods of 3 to 30 days. They come in both fixed‑data and daily‑data‑cap formats: fixed‑data plans provide a set amount of data for the entire validity period, while daily‑data‑cap plans allocate a portion of the total data each day. All plans allow tethering and include a reduced speed option of up to 1000.
