Astaroam eSIM Data Plans for Saint Martin

Astaroam does not provide a truly unlimited data eSIM for Saint Martin. The plans that carry “Unlimited” in their name give travelers 3 GB per day for a fixed number of days; when the daily allowance is exceeded the speed is throttled to 1000 kbps. All other plans have a hard data cap, such as a 10 GB bundle valid for 30 days or a 5 GB bundle also valid for 30 days, and these are considered fixed‑data plans. These fixed‑data options are more cost‑effective for most users and give a known quantity of high‑speed data.

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.
