Voyasim does not provide an unlimited data eSIM for Singapore. The available plans for Singapore are fixed data plans, such as the Singapore 50GB 30Days plan and the Singapore 20GB 30Days plan, which offer 50GB and 20GB of high‑speed data respectively for a validity of 30 days.
Choosing a fixed data plan can be more cost effective for most travelers, unless the user is an extremely heavy data consumer who would require a larger or unlimited data allowance.
