Refund policy

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.

WorldSIM: Unused, unopened items can be returned within 14 days for a full refund minus postage; faulty products are exchanged or refunded after testing confirms the fault.

Validity starts

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.

WorldSIM: Lifetime validity on the airtime credit itself, as long as you top up at least once within the airtime validity period (30/90/180/365 days depending on the bundle bought) to keep it active.

Fair-use limit

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.

WorldSIM: Not confirmed yet

Top-ups & rollover

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.

WorldSIM: Pay-as-you-go: top up airtime credit any time it runs low (via account or short-code), then convert credit into data/call/SMS bundles for any destination — no new eSIM or QR scan needed.
