Refund policy

co:sim: Uninstalled eSIMs refunded unconditionally within 30 days of purchase; once installed, refundable only for a technical issue on co:sim's side.

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

co:sim: Not confirmed yet

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

co:sim: Daily plans throttle to a lower speed (e.g. 512Kbps) once the daily limit is reached; total-data plans simply stop once depleted.

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

co:sim: Top up your balance anytime on the website -- instant, choose from various amounts; PAYG deducts per MB, data packages from $0.90/GB.

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.
