merdata does not provide an unlimited‑data eSIM for Vanuatu. All plans presented by merdata that are available for Vanuatu have a finite data cap, the largest being 20 GB for a 30‑day period.
Travelers who need substantial mobile data can choose from one of merdata’s fixed data plans, such as the 20 GB 30‑day bundle for Vanuatu or the 10 GB 30‑day options. These plans offer a clear data allowance with a defined validity period and may be more economical for most users, although individuals who anticipate extremely heavy data usage might seek additional top‑ups or alternative providers.
