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.

KnowRoaming: Full refund if the eSIM was never installed or the plan never connected; after that a full or partial refund is discretionary (under 2% of data used, or a fault on their side). Ask within 90 days of purchase and before validity ends; reviewed within 4 working days, paid within 15 calendar days.

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).

KnowRoaming: The plan starts when you first connect in a supported country, not at purchase; validity days count from that first connection and run continuously. It must be started within the 'Activate before' window shown at checkout. Unused data expires with the validity period, no rollover.

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.

KnowRoaming: Unlimited country plans: 5 GB at full speed every 24 hours, then reduced speed until the allowance resets (24h counted from first connection); the Global unlimited plan gets 2 GB a day, then up to 256 kbps. Hotspot use counts against the allowance. Fixed plans stop when the data is used.

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.

KnowRoaming: Top up from My plans in the app or on knowroaming.com: select the plan, tap Top up, choose extra data or days; no new eSIM, nothing to scan, the connection doesn't drop. Optional auto top-up (off by default) charges the saved card when the plan runs low.
