ZenSim eSIM Data Plans for Asia

ZenSim does not provide truly unlimited high‑speed data plans for Asia. The entries that carry “Unlimited” in their names give a fixed high‑speed allowance of 3 GB per day; once that amount is used, the speed is reduced to 1000 kbps. Travelers who need more data and want to avoid throttling can choose from ZenSim’s fixed‑data plans such as the Asia+ 40GB‑30 days plan or the Asia+ 20GB plans (15‑day or 30‑day options). These plans offer larger data caps while maintaining speed until the allotted data is consumed, after which the plan expires.

ZenSim does not offer any Asia eSIM plans that include a local phone number or SMS capability. Only data‑only plans are available from the provider. Travelers can use VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. Some destinations may block or restrict these apps, so it is advisable to verify their accessibility in the specific Asian destination before purchasing.

ZenSim offers two plans that cover a wide range of Asian countries. The Asia+ plan includes Bangladesh, China, Hong Kong, Indonesia, India, Japan, South Korea, Sri Lanka, Malaysia, Philippines, Pakistan, Singapore, Thailand, Taiwan, and Vietnam. The Global plan adds coverage for United Arab Emirates, Armenia, Azerbaijan, Bahrain, Brunei, Israel, Jordan, Kuwait, Kazakhstan, Oman, Qatar, Saudi Arabia, Turkey, and Uzbekistan, while also covering all the countries listed in the Asia+ plan.
