Refund policy

Cellesim: Refunds only for technical failures caused by Cellesim that support can't resolve; locked/incompatible phones, user error (e.g. deleting the eSIM), wrong-device installs and change of mind after delivery are non-refundable.

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

Cellesim: The validity countdown does not start at install - it begins only when the eSIM first connects to the network at your destination, so installing early does not waste days.

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

Fair-use limit

Cellesim: Carriers throttle the connection after the high-speed cap (often 5-20GB depending on tier); Plus/Premium tiers keep full speed longer.

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

Cellesim: Where a top-up is offered for your eSIM, add data from your Cellesim account or app to the same eSIM profile without reinstalling; if none is available you need to buy a new plan.

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

Lost device / reinstalling

Cellesim: Deleting the eSIM or installing on the wrong device is treated as non-refundable per terms; no reinstall or device-transfer option is described.

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

Cellesim: Checkout shows a currency selector (for example USD) and displays prices/top-ups in your chosen currency; no specific conversion-fee disclosure was found.

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