Policies compared

Confirmed from each provider's own site — see the trust card on each provider page for the verification date.

ID verification

ASimGo: Not confirmed yet

ZenSim: Not required

Refund policy

ASimGo: Full refund/replacement if the eSIM never activates, or a verified connectivity issue cannot be resolved by support. No refund for change-of-mind, unused data after the plan validity expires, a wrong email at checkout, or device/carrier-lock issues (a 2.50 SGD or 10% fee may apply there).

ZenSim: Refunds are not available once the eSIM has been installed or activated, except for a technical failure verified by ZenSim. If a Travel eSIM cannot be used due to device incompatibility, a refund is issued only if it has not been installed/activated on a different device.

Validity starts

ASimGo: Most plans activate only when the eSIM first connects to a supported network, not on purchase — install it just before departure or on arrival using airport Wi-Fi, per their FAQ.

ZenSim: Validity starts on activation, not purchase — the eSIM auto-activates the first time it connects to the destination network. Must be installed within 12 months of purchase or ZenSim may cancel the order.

Fair-use limit

ASimGo: Not confirmed yet

ZenSim: Unlimited plans include a fixed daily high-speed allowance (see each plan), then drop to a reduced speed for the rest of that day.

Top-ups & rollover

ASimGo: Not confirmed yet

ZenSim: Every Travel eSIM can be topped up from the ZenSim app — no need to buy a new eSIM.
