Refund policy

Giga.tel: Full refund only if the eSIM hasn't been installed and no data was used - contact within 5 days of purchase with your order number. If a technical issue (won't download, won't connect) can't be resolved, a refund/partial refund may still be given.

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.

Validity starts

Giga.tel: Standard eSIM plans: validity starts when the plan is activated, not at purchase (confirmed at checkout). A separate 'Connectivity' plan type instead starts immediately after purchase.

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).

Fair-use limit

Giga.tel: Unlimited plans carry a fair-use policy - each plan's own page shows its Daily Allowance and the post-threshold speed; there's no single sitewide GB/day figure or throttle speed.

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

Top-ups & rollover

Giga.tel: Add a top-up or a new plan to the same reusable eSIM at any time without reinstalling - just keep the eSIM profile on your device rather than deleting it.

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

Lost device / reinstalling

Giga.tel: If a technical/connectivity issue arises, support will troubleshoot or issue a replacement when eligible. Exception: the 'Connectivity' plan type can't be replaced if not installed within 24 hours of receiving the QR code.
