Roambit does not provide an unlimited data eSIM for Malaysia. All of its plans for the country have a specific data cap and a fixed validity period.
The available options are fixed data plans with large allowances, such as the Penang 100GB 30d plan, the Asia 50GB 30d plan, and the Penang 20GB 30d plan. These examples are handpicked for their high data limits and represent only a subset of the plans Roambit offers; they can be more cost‑effective for most travelers unless the user is an extremely heavy data consumer who might need a different type of plan.
