ZenSim for Southeast Asia FAQ

Does ZenSim offer unlimited data eSIM for Southeast Asia?

ZenSim does not provide an unlimited data eSIM for Southeast Asia. The plans that carry “Unlimited” in their name, such as Asia+ Unlimited STANDARD, actually give 3GB per day of high‑speed data; once that daily allocation is used, speed is throttled to 1000 kbps. Therefore those plans are not truly unlimited.

For travelers who need a large amount of data, ZenSim offers fixed data plans. For example, the Asia+ 40GB plan is valid for 30 days and the Asia+ 20GB plan is also valid for 30 days, both covering Indonesia, Malaysia, Philippines, Singapore, Thailand, Vietnam, and nine additional countries. These fixed data plans allow the full data allowance to be used within the validity window and can be more cost‑effective for heavy‑data users compared to a plan that reduces speed after a set limit.

Does ZenSim offer Southeast Asia eSIM with phone number and SMS?

ZenSim does not offer any eSIM plans for Southeast Asia that include a phone number or SMS capability. Travelers looking for local voice or text services will only find data‑only options from ZenSim in this region.

For voice and messaging, users can rely on VoIP applications such as WhatsApp, Telegram or iMessage over the data connection. However, some destinations in Southeast Asia may block or restrict access to specific apps or VoIP services, so it is advisable to verify that the apps you need are usable in the countries you plan to visit before purchasing a ZenSim eSIM.

What countries are covered by ZenSim's eSIM plans in Southeast Asia?

ZenSim offers two plans that cover Southeast Asian markets: the Asia+ plan, which covers Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam; and the Global plan, which includes Brunei, Indonesia, Cambodia, Malaysia, Philippines, Singapore, Thailand, and Vietnam.
