4S eSIM eSIM Data Plans for Asia

4S eSIM does not offer a true unlimited data eSIM for Asia. The plans listed under the “Unlimited” name all have a fixed data cap. For example, the Asia+ 50GB Unlimited – 5 Days plan provides 50GB of data in five days, and the Asia+ 20GB Unlimited – 5 Days plan supplies 20GB of data in five days. Both plans come with a hard limit and, if the data cap is reached, the speed reduces to 1000kbps. Choosing a fixed‑data plan may be more cost‑effective unless one is an extremely heavy data consumer, in which case a higher‑cap plan such as the 50GB option could be appropriate.

4S eSIM does not provide an Asia eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are available from this provider for Asia. Travelers who need voice or messaging can set up popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may restrict access to these services so callers should verify availability before purchasing.

The Asia+ plan covers China, Hong Kong, Indonesia, Japan, South Korea, Malaysia, Philippines, Singapore, Thailand, Taiwan, and Vietnam. The Global plan expands this coverage to include China, Georgia, Hong Kong, Indonesia, India, Japan, Kyrgyz Republic, Cambodia, South Korea, Kazakhstan, Sri Lanka, Malaysia, Philippines, Pakistan, Singapore, Thailand, Turkey, Taiwan, Uzbekistan, and Vietnam.
