ZenSim does not provide a truly unlimited data eSIM plan for Southeast Asia. The Asia+ Unlimited STANDARD plans list 3GB per day for 5, 15, or 30 days; after reaching the daily 3GB limit the connection speed is typically throttled. If a traveler requires more data, several fixed‑data options are available, such as the 40GB plan for 30 days or the 20GB plan for 15 or 30 days. These plans offer a larger total data allowance and may be more cost‑effective for heavy data users compared to the daily‑limited “Unlimited” offerings.
ZenSim does not offer eSIM plans that include a phone number or SMS capability for Southeast Asia. The provider sells only data‑only eSIMs, so travelers will not receive an inbound or outbound voice line or SMS service on this network.
Users who need voice or text communication can rely on internet‑based applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection that the ZenSim eSIM provides.
ZenSim’s Asia+ eSIM plan provides coverage in six Southeast Asian countries: Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam. This plan also includes access to other regions such as Bangladesh, China, Hong Kong, India, Japan, South Korea, Sri Lanka, Pakistan, and Taiwan, but its Southeast Asian coverage is limited to the six nations listed above.
