– hereinafter "Provider" – and customers through the website withavelis.com (hereinafter "Website") or other digital channels of the Provider.

2.4 To use the eSIM, the customer requires an eSIM-compatible and network-unlocked device. A list of compatible devices is available on the Website. The Provider does not guarantee compatibility with any specific device.
3.1 The presentation of products on the Website does not constitute a binding offer, but an invitation to submit an offer (invitatio ad offerendum).
3.2 The customer submits a binding offer by completing the order process (clicking "Order with obligation to pay" or an equivalent button).
3.3 A contract is formed only upon dispatch of the order confirmation by email. The order confirmation includes a summary of the order as well as the QR code or activation link for the eSIM.
3.4 The Provider reserves the right to refuse a customer's offer without giving reasons, in particular in the event of payment defaults or suspected misuse.

4.3 For subscriptions, payment is charged upon commencement of the subscription and subsequently automatically at the beginning of each renewal period, unless the subscription has been cancelled in advance.
4.4 In the event of unauthorised chargebacks or payment defaults, the Provider reserves the right to suspend access to the eSIM and to assert claims for dunning costs and other damages.
5.1 The eSIM is provided exclusively in digital form. After successful payment, the customer receives a QR code by email and/or an activation link for installation directly in the browser.
5.2 Delivery usually takes place within a few minutes after receipt of payment. The Provider accepts no liability for delays caused by external service providers (e.g. email providers) or technical disruptions on the customer's side.
5.3 If the customer does not receive the eSIM within 30 minutes, they should first check their spam/junk folder and then contact customer support.
5.4 Each QR code and activation link may only be used once. The customer is responsible for keeping it secure.

6.3 The Provider is entitled to terminate subscriptions with 30 days' notice, in particular if the underlying network product is discontinued or prices increase materially. The customer will be informed in advance in such cases.
6.4 Price changes for current subscriptions will be communicated to the customer at least 30 days before they take effect by email. If the customer does not object within this period, the price change shall be deemed accepted as of the beginning of the next renewal period. In the event of objection, the customer has the right to cancel the subscription by the end of the current period.
7.1 The customer may top up an active eSIM at any time with an additional data package or a validity extension.
7.2 Top-ups are treated as separate one-time purchases and are credited immediately after payment.
