12 CountriesFrequently Asked Questions
Does ZenSim offer unlimited data eSIM for Southeast Asia?
ZenSim does not provide a truly unlimited highโspeed data eSIM for Southeast Asia.
The plans labeled โAsia+ Unlimited STANDARDโ actually include a 3GB/day data cap; once that limit is reached the speed is reduced, so the data is not unlimited.
Travelers looking for large data allowances can choose from a range of fixedโdata plans. For example, the Asia+ 20GB plan is available for 10 days or 30 days, and the Asia+ 10GB and Asia+ 5GB plans offer similar options. These fixed plans can be more costโeffective, especially for those who need a substantial amount of data but are not extreme heavy consumers.
Does ZenSim offer Southeast Asia eSIM with phone number and SMS?
ZenSim does not offer eSIM plans that include a phone number or SMS capability for Southeast Asia. The provider sells only dataโonly 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 internetโbased applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection that the ZenSim eSIM provides.
What countries are covered by ZenSim's eSIM plans in Southeast Asia?
ZenSim offers the Asia+ plan, which covers Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam in Southeast Asia.
