Refund policy

InternationalSIM: 14-day money-back guarantee: full refund if the eSIM QR code has not been scanned or activated, processed to the original payment method in 3–5 business 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

InternationalSIM: Smartstart: plans activate automatically on arrival in a covered destination, with the validity period starting then, not at purchase; unactivated plans expire automatically 6 months after purchase.

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

Fair-use limit

InternationalSIM: Data services are subject to Fair Use Policies set by the local network carrier per InternationalSIM's terms, but no specific data threshold or throttled speed is disclosed.

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

InternationalSIM: Existing eSIMs and SIM cards can be recharged with more data through the InternationalSIM customer portal without needing a new eSIM.

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

Lost device / reinstalling

InternationalSIM: A new eSIM would be required.

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

InternationalSIM: All InternationalSIM product listings and checkout prices are calculated and charged in EUR (€), including VAT.

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