Yatelo does not have a true unlimited data eSIM for Malaysia.
All of the plans listed on the Yatelo catalogue for Malaysia are fixed data bundles. In the “Unlimited” family of plans, the data cap is 2GB and after that amount the speed drops to a reduced level (for example 384 kbps).
If you need a higher amount of high‑speed data, Yatelo offers larger fixed plans such as the 50 GB 30 days bundle for $23.49 USD and the 20 GB 30 days bundle for $10.99 USD, both of which are available for Malaysia and include 5G and tethering support. These options are often more cost‑effective for travelers who need a substantial amount of data without a hard cap on usage.
