MobiMatter does not provide an unlimited data eSIM for Guyana. The available plans are fixed data bundles, each with a specific data cap and validity period. For example, the Best World 50 GB plan is valid for 180 days, the Caribbean 20 GB plan is valid for 30 days, and the Discover Global 10 GB plan is also valid for 30 days. Other options include the Best World 10 GB and Caribbean 10 GB plans, each with a 30‑day validity.
Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user is an extremely heavy data consumer who would benefit from a truly unlimited plan.
