Refund policy

AeriSIM: Full or partial refund, or a replacement, if the eSIM can't be installed or used due to a fault on AeriSIM's or the carrier's side; incompatible or carrier-locked phones are refunded minus $2 or 10% (whichever is higher). No refund once installed, for changed plans, or after the activation window.

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

AeriSIM: Validity starts once the eSIM connects to a supported network and begins using data; you can install before departure but keep it switched off. Some plans start on installation or a fixed date, as stated on the product page.

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

AeriSIM: Varies by plan and is listed on each product page: daily plans slow down after the daily high-speed allowance (e.g. Japan: 128 kbps, resets 0:00 UTC+8); some unlimited plans have a stated speed cap instead.

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

AeriSIM: Depends on the plan: check My eSIMs and the order details; if a top-up is not offered, buy another plan for the same destination.

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.
