Astaroam eSIM Data Plans for Caribbean

Astaroam does not provide an unlimited data eSIM plan for the Caribbean. All of its Caribbean offerings are fixed data plans with set data caps and validity periods.

Travelers who need a larger data allowance can choose from Astaroam’s fixed plans, such as the 10 GB plan valid for 30 days or the 5 GB plan also valid for 30 days. These plans give a clear data limit and a defined validity window, which can be more cost‑effective for most users unless they require truly unlimited data.

Astaroam does not provide eSIM plans for the Caribbean that include a phone number or SMS capability. The available options are data‑only plans only.

Travelers who need to make calls or send messages can use VoIP apps such as WhatsApp, Telegram, or iMessage over the data connection. Some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you rely on are available in the Caribbean before purchasing an Astaroam plan.
