Avelis eSIM does not provide an unlimited data plan for Barbados. The only options are fixed data plans with caps of 5GB, 10GB, or 20GB that are valid for 30 days. For example, the 20GB / 30‑day plan costs $118.99 USD, the 10GB / 30‑day plan is $62.99 USD, and the 5GB / 30‑day plan is $31.99 USD. Some of these plans include 5G coverage and support tethering.
Choosing a fixed data plan can be more cost‑effective unless a traveler expects very heavy usage. The higher‑capacity plans, such as the 20GB option, offer the greatest amount of data for the price in a single 30‑day window.
