Refund policy

JamboSim: 30-day window from purchase. Full refund for a confirmed technical/supply fault, duplicate charge, or a charge with no eSIM delivered. No refund once the eSIM is installed/activated regardless of usage, for coverage/speed disappointment, cancelled trips, or an unused-but-expired eSIM. Refunds via Stripe to the original payment method, 5-10 business days; 2-day response, 7 days to complete once approved.

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

JamboSim: Plan validity starts on activation, not purchase; the exact window is shown per plan (e.g. 3, 7, 15, 30 days from first connection).

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

JamboSim: Unlimited plans are fair-use capped at 3GB high-speed data per day, then reduced speed for the rest of that day.

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

JamboSim: Top up an existing eSIM from your JamboSim account anytime - the extra data is added to the same profile, no reinstall needed.

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