Refund policy

BuyUKeSIM: Routine refunds aren't offered once the eSIM QR is delivered (standard for instant digital goods) - but technical delivery failures, duplicate payments, overpayments and confirmed payment errors are reviewed and fixed case by case via live chat or Telegram, TX hash required.

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

BuyUKeSIM: Shown per plan at checkout: validity starts on first network connection, not at purchase or QR delivery.

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

BuyUKeSIM: Not confirmed yet

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

BuyUKeSIM: Add a data top-up to an already-installed eSIM from your order page (8-character Magic Code) - loads onto the same eSIM, same QR/ICCID, no reinstall, repeatable. Unused data doesn't roll over past the plan's own expiry.

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.
