Trifa does not sell an unlimited data eSIM for Martinique. The provider’s catalog for the island consists of fixed‑data plans, the largest of which offer 100 GB of high‑speed data valid for 3 to 15 days. For example, a 100GB plan can be purchased for 3 days at $18.36 USD or for 10 days at $49.38 USD. Choosing a fixed‑data plan can be more cost‑effective for most travelers, unless a user requires a truly unlimited data allowance.
