Yes, Earth Esim offers several unlimited‑data eSIM plans that work in Malaysia. The unlimited plans are available in various validity periods ranging from 1 day to 30 days. Prices for these plans start at about $2.49 USD for a single‑day 5 G plan and go up to roughly $56.25 USD for a 30‑day 5 G plan. All unlimited plans include tethering, may have their speeds throttled after heavy use, and the maximum speed is limited to the value listed in the plan (for example, 1000 kbps, 5000 kbps, or 10000 kbps). If you are concerned about possible speed reductions after high usage, it is advisable to contact Earth Esim directly to confirm whether a Fair Usage Policy applies and what the typical data volume available at normal speed is.
