Refund policy

Billion Connect: Refundable before activation; once activated/used, refund rights end; third-party partner purchases are excluded from refunds.

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

Billion Connect: Most plans start when the eSIM first connects to a supported network at your destination (some start on installation, as the product page states); activate within 90 days of purchase; a day = 24 hours from activation.

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

Fair-use limit

Billion Connect: Set per plan on the product page: most plans drop to a reduced speed (typically 128–384 kbps) after the high-speed allowance, daily or total, instead of cutting off; a few plans stop at the limit.

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

Billion Connect: Standard eSIMs can't be topped up; buy a new plan when data runs out. eSIM Air supports top-ups anytime without reinstalling.

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

Lost device / reinstalling

Billion Connect: Most eSIMs can be reinstalled or moved to a new phone by rescanning the original QR code; plans marked non-reinstallable on the product page are lost once deleted.

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

Billion Connect: Multi-currency checkout: USD, HKD, JPY, KRW, EUR, CNY, TWD, CAD, SGD, THB, MYR.

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