Astaroam eSIM Data Plans for Martinique

Astaroam does not provide a true unlimited‑data eSIM for Martinique. Their plans labeled “Unlimited” actually provide 3GB of high‑speed data each day for the chosen validity period, after which the speed is reduced to 1000kbps.

If you need more data without a daily cap, Astaroam offers fixed‑data options such as a 10GB plan for 30 days at $45.15 USD or a 5GB plan for 30 days at $26.72 USD, both of which allow tethering and are delivered over 5G. These plans may be more cost‑effective unless you are an extremely heavy data user.

Astaroam does not provide a Martinique eSIM that includes a local phone number or SMS capability. Travelers using an Astaroam eSIM for Martinique will have access to data only, which allows the use of VoIP applications such as WhatsApp, Telegram, and iMessage for calls and messaging. As with any destination, some VoIP services may be blocked or restricted, so it is advisable to verify that the specific apps you rely on can be used in Martinique before purchasing the plan.

Astaroam provides five single‑country data plans specifically for Martinique, and an additional five multi‑country plans that cover the island as part of a broader regional package. The catalogue includes both fixed‑data plans, which grant a one‑time data allotment that lasts the entire validity period, and daily‑cap plans that provide a daily data allowance that rolls over for the duration of the plan. Prices for the available options start around $3.93 and rise to roughly $45.15, with data caps ranging from 1 GB up to 10 GB, and validity periods spanning 3 to 30 days.
