Halo eSIM eSIM Data Plans for Martinique

Halo eSIM does not offer a truly unlimited data eSIM for Martinique; the plans that carry “Unlimited” in the name give 3GB of high‑speed data per day, after which the speed is throttled to 1 Mbps for the rest of the day. This limit is not a hard cap but a daily allocation that resets each day, and the “unlimited” label refers to the continuation of the plan rather than unbounded data.

For travelers needing higher data volumes, Halo eSIM provides fixed data plans of 20 GB, 10 GB, 5 GB, 3 GB, and 10 GB/30 days. These plans provide a single data allowance for the full 30‑day validity period at full speed, making them more cost‑effective for high‑usage trips to Martinique.

Halo eSIM does not provide a phone number or SMS capability for Martinique. Only data‑only eSIM plans are available from this provider for that destination.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these apps are accessible in Martinique before purchasing a plan.

Halo eSIM offers 12 single‑country plans that cover Martinique and 3 multi‑country plans that include Martinique as part of a broader region. The available plans span a price range of about $3.95 to $70.70 and data caps from 1 GB to 20 GB. Some plans provide a fixed data amount, while others implement a daily data cap, giving travelers flexibility in choosing the type that best matches their usage patterns.
