Yesim offers several unlimited‑data eSIM options that cover Malaysia. The available plans run for 1 day, 7 days, 15 days or 30 days, with prices ranging from $8.14 USD for a 1‑day South East Asia plan to $68.64 USD for a 30‑day Malaysia‑only plan. These plans are marked as unlimited, but the description notes that speeds may be throttled after a certain level of use; normal speed may later be capped at an unspecified rate. The provider applies a Fair‑Usage Policy, meaning that heavy usage could result in reduced speeds. Travelers who want to know the typical amount of data that remains at normal speed, or who need clarification on the throttling threshold, are encouraged to contact Yesim directly for up‑to‑date details.
