ZenSim for Southeast Asia FAQ
Does ZenSim offer unlimited data eSIM for Southeast Asia?
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.
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?
