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.

Yesim: Refunds within 30 days of purchase only if the plan/top-up hasn't been activated, used or expired (installing the eSIM profile counts as activation); approved refunds go to the original payment method, but amounts of €10 or less are credited as Ycoins.

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.

Yesim: You select a desired activation time when purchasing a plan in the app -- validity is not automatically triggered 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.

Yesim: Yesim itself does not enforce a Fair Usage Policy on its Unlimited plans, but some of its partner network providers may apply their own FUP as part of their own terms, per Yesim's Help Center.

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.

Yesim: Additional data can be bought at any time from the Yesim app or website, added to the same eSIM.

Lost device / reinstalling

KnowRoaming: KR.One is one eSIM installed once; every later plan attaches to it with no new QR code. A deleted eSIM can't be restored or moved to another phone; a fresh one is added through the app in about a minute, while a plan with days or data left stays on the phone it was bought for.

Yesim: Yesim eSIM profiles use a one-time activation code -- don't remove the profile or rescan the QR code, as that can wipe your settings; if lost or it fails to install, contact Yesim support for a new QR code.

Billing currency

KnowRoaming: Charged in the currency shown at checkout (website: your region's currency; app: Settings > Currency). A card in another currency is converted by the card network at its own rate; KnowRoaming advises declining the bank's dynamic currency conversion offer. Card details are held by Stripe.

Yesim: Based on the pre-selected currency on the account. Yesim accepts EUR, AUD, CAD, PLN, GBP, USD
