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.

Saily: Full refund if the eSIM has not been installed or the data plan was never activated; after activation, refunds only while more than 99% of the data balance remains unused (subscriptions: within 14 days).

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.

Saily: Saily plans must be installed before your trip; the validity/data countdown starts when the eSIM activates (first connection at your destination), not at purchase.

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.

Saily: Unlimited plans include a Fair Use Policy: full-speed data resets every 24 hours (5GB standard, as low as 3GB in some countries), then speed is reduced until the next reset.

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.

Saily: Existing Saily eSIMs can be topped up (including an Auto Top-Up option) directly in the Saily app without reinstalling, per their Help Center.
