Refund policy

SimSmash: Full refund if the eSIM has not been activated. Once activated, a partial refund pro rata to the unused data is offered within 24 hours of purchase. Contact support.

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

SimSmash: Validity starts on activation, not on purchase; the eSIM can be bought up to 30 days before departure.

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

Fair-use limit

SimSmash: Not confirmed yet

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

SimSmash: Some plans can be topped up directly when the Top-Up option is shown; otherwise buy a new plan, delivered by email immediately.

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

Lost device / reinstalling

SimSmash: Not confirmed yet

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

SimSmash: Priced in USD, no taxes added. The listed price is final with the SimSmash wallet or crypto; card payments (Stripe) add a 4.4% fee at checkout, shown before payment.
