ZenSim for Southeast Asia FAQ
Does ZenSim offer unlimited data eSIM for Southeast Asia?
ZenSim does not offer a truly unlimited high‑speed data eSIM for Southeast Asia. The plans labeled “Unlimited” in ZenSim’s catalogue provide a fixed amount of high‑speed data—3 GB per day for the “Asia+ Unlimited STANDARD” plans—after which the speed is throttled.
If higher data usage is required, ZenSim offers fixed‑data plans that cover the same Southeast Asian countries. Examples include the “Asia+ 20GB” plans for 10 or 30 days and the “Asia+ 10GB” plans for 10 or 30 days. These fixed‑data options provide more cost effective coverage for travelers who need a reliable amount of high‑speed data.
Does ZenSim offer Southeast Asia eSIM with phone number and SMS?
