ZenSim for Southeast Asia FAQ
Does ZenSim offer unlimited data eSIM for Southeast Asia?
ZenSim does not provide a truly unlimited data eSIM for Southeast Asia. Every plan in its catalog has a defined data cap. The plans that include “Unlimited” in their name, such as Asia+ Unlimited STANDARD – 5 days, Asia+ Unlimited STANDARD – 15 days, and Asia+ Unlimited STANDARD – 30 days, actually give 3 GB of high‑speed data per day and then throttle the speed to 1000 kbps once that daily quota is reached.
Travelers who need larger amounts of data can choose ZenSim’s fixed data plans, for example Asia+ 40GB for 30 days or Asia+ 20GB for 30 days. Both options provide 40 GB or 20 GB of data, respectively, with validity periods of 30 days, and they cover Indonesia, Malaysia, Philippines, Singapore, Thailand, Vietnam and nine additional Southeast Asian countries. These fixed plans can be more cost‑effective for users who require a substantial data allowance.
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.
