a) in the case of an eSIM Card — making the QR code and eSIM configuration data available to the Customer (revealing them) in the Account or sending them to the specified e-mail address; and

b) in the case of a SIM Card — Activation of the SIM Card within the Operator’s network.

Service Performance Date. The Service Performance date is indicated by the Customer after placing the Order by specifying the Activation date in the Activation form. The Customer is obliged to specify the Activation date no later than 48 hours before the planned Activation. Right of Withdrawal (Consumer). A Consumer has the right, under the terms specified in the Consumer Rights Act of 30 May 2014, to withdraw from a distance contract without giving any reason within 14 days from the date of concluding the agreement or taking possession of the purchased SIM Card (depending on the type of product). Exclusion of the Right of Withdrawal after Service Performance. Pursuant to Article 38(1) of the Consumer Rights Act, the right to withdraw from an agreement does not apply to a service agreement for which the Consumer is obliged to pay a price if the entrepreneur has fully performed the service with the Consumer’s express prior consent and after informing the Consumer before performance begins that, once the service has been fully performed, the Consumer will lose the right of withdrawal. Consent to Begin Performance before the Withdrawal Period Expires. In the Activation form, the Customer selects the Activation date. If the selected Activation date falls before the expiry of 14 days from the conclusion of the agreement, the Customer — being a Consumer — shall, prior to Activation, provide an explicit declaration:

a) requesting commencement of the service before the withdrawal period expires; and

b) acknowledging that, after Service Performance, the right to withdraw from the agreement will be lost. The declarations referred to in points a and b are submitted by the Consumer by selecting a separate checkbox when specifying the Activation date in the Activation form, no later than before Activation. The checkbox is not pre-selected. Without these declarations, Activation may not be carried out before the expiration of 14 days from the conclusion of the agreement.

Refund before Service Performance. Withdrawal from the agreement by a Consumer before Service Performance entitles the Consumer to a refund of the full amount paid for the SIM Card or eSIM. The refund shall be made to the bank account associated with the payment method used by the Consumer within 14 days of receipt of the withdrawal declaration. No Refund after Service Performance. After Service Performance — i.e. after the QR code has been revealed (eSIM) or the SIM Card has been Activated — the right to withdraw from the agreement expires in accordance with section 4. Customer claims relating to a SIM Card or eSIM after Service Performance shall be considered exclusively under the complaint procedure (§ 12) or, where applicable, under the Money Back Guarantee procedure (§ 12 section 1(a)). Model Withdrawal Form. The Consumer may use the model withdrawal form constituting Appendix No. 2 to these Terms and Conditions; however, this is not mandatory. A declaration of withdrawal may be submitted in any written or electronic form, in particular to the Customer Service Office e-mail address or via the electronic withdrawal function referred to in section 9. Information regarding the right of withdrawal is provided in Appendix No. 1 to these Terms and Conditions. Electronic Withdrawal Function. Regardless of the methods indicated in section 8, the Consumer may submit a declaration of withdrawal through the electronic function (“Withdraw from the Agreement”) made available on the Store website and in the mobile application, including for Customers who do not have an Account (guest checkout). The function leads to a withdrawal form enabling identification of the agreement (in particular by Order number and e-mail address) and is available throughout the entire withdrawal period. Submission of a declaration through this function is a two-step process: after completing the form, the Consumer confirms the declaration by means of a separate, clearly marked button confirming withdrawal. The Consumer may withdraw from the entire agreement or only from part of it (selected Order items). The Seller shall immediately provide the Consumer, on a durable medium and to the specified e-mail address, confirmation of receipt of the withdrawal declaration, including in particular the date and time of submission and the Order number.

§ 10. Ownership of the SIM Card and Deactivation

The Customer acquires only the right to use those services for the period and within the scope specified in the selected Package. Deactivation. The Seller is entitled to deactivate (disable) a SIM Card or eSIM at any time, in particular in the event of:

a) failure by the Customer to pay the full price or any other amount due to the Seller,

b) expiration of the Package validity period,

c) violation by the Customer or User of these Terms and Conditions, promotional regulations, or generally applicable laws,

d) reasonable suspicion that the SIM Card or eSIM is being used for unlawful purposes, in particular fraudulent activities, artificial traffic generation, or the distribution of unsolicited communications,

e) a request to do so by the Operator,

f) force majeure or other circumstances beyond the Seller’s control preventing further provision of services,

g) resolution of a complaint regarding the service resulting in a refund to the Customer (including under the Money Back Guarantee) with respect to the SIM Card or eSIM covered by such refund, provided deactivation is possible.

Effects of Deactivation. Deactivation results in the immediate suspension of the ability to use the Operator’s telecommunications services associated with the relevant SIM Card or eSIM. In the cases referred to in section 2(c) and 2(d), the Seller may seek compensation from the Customer or User under the general rules of the Civil Code.

§ 11. Telephone Number

Status of the Number. The telephone number (subscriber number) assigned to the SIM Card or eSIM is allocated by the Operator and remains at the Seller’s disposal. The number is not the property of the Customer or User — the Customer and User acquire only the right to use the number during the validity period of the Package and under the conditions specified in these Terms and Conditions. Previously Used Numbers (Recycled Numbers). The Customer and User acknowledge that telephone numbers provided by the Operator may have previously been assigned to other subscribers. As a result, calls, SMS messages, or other communications unrelated to the Customer or User (in particular those intended for a previous user of the number) may be received on the SIM Card or eSIM. The Seller shall not be liable for the receipt of such communications or for their content. Number Change — Seller Assistance. At the request of the Customer or User, the Seller shall, to the extent permitted by the Operator’s technical capabilities, provide free assistance in changing the number assigned to the SIM Card or eSIM.

The Customer or User may request to retain the telephone number assigned to the SIM Card or eSIM outside the Seller’s services, in particular by transferring the number to another telecommunications operator. Such a request may only be fulfilled to the extent permitted by the technical capabilities and regulations applicable within the Operator’s network. Fee. For retaining the number outside the Seller’s services (in particular transferring it to another operator), the Seller charges a fee compensating for the cost of losing the number with the Operator and the costs of handling the operation. The fee constitutes compensation for the Seller’s actual costs and does not constitute a contractual penalty. The amount of the fee and the method of its calculation are specified in the Price List.

§ 12. Complaints

Two Complaint Resolution Paths. The Customer has access to two methods of handling concerns relating to a SIM Card or eSIM:

a) Money Back Guarantee — an additional service offered by the Seller, constituting an accelerated procedure, available under the terms specified in a separate set of regulations available in the Store. The possibility of using the Money Back Guarantee arises in the situations and under the conditions specified therein;

b) Standard Complaint Procedure — the procedure described in this section, applicable where the Money Back Guarantee does not apply or the Customer chooses not to use it.

Method of Submission. Standard complaints shall be submitted electronically to kontakt@kartysimusa.pl or in writing to the Seller’s registered office address. The complaint should contain information enabling identification of the Customer (in particular the e-mail address assigned to the Account or the Order number), a description of the concerns raised, and the preferred method of resolution. Complaint Handling Period. The Seller shall consider complaints within 14 days from the date of receipt, subject to section 4. Verification of the Complaint in the Country of Service Provision. The Customer and User acknowledge that, due to the nature of the telecommunications service provided by the Operator outside the territory of the Republic of Poland, verification of the cause and validity of a standard complaint may only be carried out in the country where the service is provided, in particular within the territory of the United States of America. Where such verification is necessary to resolve the complaint, the Seller shall inform the Customer of this circumstance and, if necessary, of the extension of the complaint handling period by the time required to obtain information from the Operator, not exceeding the period resulting from mandatory legal provisions.

Customer Cooperation. The handling of a complaint may require the cooperation of the Customer and the User, in particular the provision of additional information necessary to verify the complaint and refraining from hindering the Seller in obtaining information from the Operator necessary to assess the validity of the complaint. Failure to provide such cooperation may make it impossible to substantively consider the complaint to the extent requiring such information. Method of Response. The Seller shall inform the Customer of the outcome of the complaint using the same method by which the complaint was submitted, unless the Customer indicates another preferred method of communication.

§ 13. Seller’s Liability — Exclusions

No Liability for the Provision of Telecommunications Services. Due to the fact that the Seller is not a telecommunications operator and only intermediates in the sale and activation of the Operator’s services, the Seller — subject to mandatory legal provisions — shall not be liable for:

a) the quality, availability, and technical parameters of the Operator’s network signal,

b) the inability to make a call, send a message, or initiate a data transmission session at a given time,

c) the Operator’s network coverage at the User’s location,

d) actions, omissions, and decisions of the Operator, in particular decisions concerning suspension, restriction, or termination of telecommunications services,

e) service unavailability resulting from force majeure, Operator infrastructure failures, maintenance work, or other circumstances beyond the Seller’s control,

f) loss, theft, damage, or destruction of the SIM Card by the Customer or User,

g) incorrect configuration of the User’s device or use of a device incompatible with the technical parameters of the Operator’s network,

h) the content of calls, messages, and other communications received by the User, including communications intended for a previous user of the number (§ 11 section 2).

Scope of Liability Toward Consumers. The provisions of this section do not exclude or limit the Seller’s liability toward Consumers to the extent that such liability arises from mandatory legal provisions, in particular provisions concerning statutory warranty and liability for non-conformity of goods/services with the agreement, however only with respect to services provided directly by the Seller and not by the Operator. Liability for the Seller’s Own Obligations. The exclusions referred to in section 1 do not apply to the Seller’s liability for improper performance of the Seller’s own obligations — in particular regarding the sale, delivery of a SIM Card, provision of an eSIM QR code, Activation on the date indicated by the Customer, and information obligations.

§ 14. Obligations of the Customer and User

The Customer and User are obliged to use the SIM Card or eSIM in accordance with applicable law, these Terms and Conditions, and the Operator’s regulations applicable in the country where the service is provided. It is prohibited to use the SIM Card or eSIM for unlawful purposes, fraudulent purposes, artificial traffic generation, activities compromising the security or integrity of the Operator’s network, or the distribution of unsolicited electronic communications. The Customer is obliged to specify the Activation date no later than 48 hours before the planned Activation. The Customer is obliged to keep confidential the Account password and eSIM access data (QR code and configuration data). Violation of the obligations referred to in this section may result in deactivation of the SIM Card or eSIM in accordance with § 10 section 2.

§ 15. Personal Data

The Seller is the controller of the personal data of Customers and Users. Detailed rules regarding the processing of personal data — including purposes, legal bases, retention periods, categories of recipients (in particular the Operator), and the rights of data subjects — are specified in the Privacy Policy available in the Store. The rules governing the use of cookies are specified in the Cookie Policy available in the Store.

§ 16. Out-of-Court Consumer Dispute Resolution

Consumers may use out-of-court methods of complaint handling and dispute resolution, in particular by:

a) submitting a request to a permanent consumer arbitration court operating at a Provincial Inspectorate of Trade Inspection for resolution of a dispute arising from the concluded agreement,

b) submitting a request to a Provincial Inspector of Trade Inspection to initiate mediation proceedings aimed at an amicable resolution of the dispute,

c) obtaining free assistance regarding dispute resolution from a district (municipal) consumer ombudsman or a social organization whose statutory purpose is consumer protection (e.g. the Consumer Federation or the Polish Consumer Association).

A list of Polish entities authorized to conduct out-of-court consumer dispute resolution proceedings and information regarding access to such procedures are available on the website of the Polish Office of Competition and Consumer Protection: https://www.uokik.gov.pl/pozasadowe_rozwiazywanie_sporow_konsumenckich.php A list of European Union entities responsible for Alternative Dispute Resolution (ADR), maintained by the European Commission, is available at: https://consumer-redress.ec.europa.eu/dispute-resolution-bodies

Appendix No. 1 to the Terms and Conditions – Information on the Right of Withdrawal

Right of Withdrawal

You have the right to withdraw from a distance contract within 14 days without giving any reason. The withdrawal period expires after 14 days:

– in the case of a SIM Card sales agreement (goods) — from the day on which you acquired possession of the SIM Card or on which a third party other than the carrier and indicated by you acquired possession of the SIM Card;

– in the case of a service agreement, including an agreement covering an eSIM Card — from the date of conclusion of the agreement.

To exercise the right of withdrawal, you must inform the Seller — Karty SIM Kamiński spółka jawna, ul. Genewska 6, 03-963 Warsaw, e-mail address: kontakt@kartysimusa.pl — of your decision to withdraw from this agreement by means of an unequivocal statement (for example, a letter sent by post or e-mail). You may use the model withdrawal form constituting Appendix No. 2 to these Terms and Conditions, but this is not mandatory.

You may also withdraw from the agreement through the electronic “Withdraw from the Agreement” function available on the Store website (https://kartysimusa.pl/) and in the mobile application. For Customers who have an Account, the function is available in the Account panel for a given order, and in the case of purchases made without an Account (guest checkout) — on a dedicated page available without logging in, linked in the Store footer and in the order confirmation e-mail. The function leads to a withdrawal form, and submission of the declaration requires confirmation using a separate, clearly marked confirmation button. Immediately after submitting the declaration through this function, we will send confirmation of its receipt to the e-mail address provided by you on a durable medium.

To meet the withdrawal deadline, it is sufficient that you send information concerning the exercise of your right of withdrawal before the withdrawal period has expired.

Effects of Withdrawal

If you withdraw from this agreement, we will reimburse all payments received from you, including delivery costs (except for additional costs resulting from your choice of a delivery method other than the least expensive standard delivery method offered by us), without undue delay and in any event no later than 14 days from the date on which we were informed of your decision to exercise the right of withdrawal. We will make the reimbursement using the same means of payment that you used for the original transaction unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.

In the case of a SIM Card (goods), we may withhold reimbursement until we have received the SIM Card back or until you have supplied evidence of having sent it back, whichever occurs first. Please return the SIM Card to the Seller’s registered office address without undue delay and in any event no later than 14 days from the date on which you informed us of your withdrawal from this agreement. The deadline is met if you send back the SIM Card before the 14-day period has expired. You will have to bear the direct cost of returning the SIM Card. You are only liable for any diminished value of the SIM Card resulting from handling it in a manner other than what is necessary to establish its nature, characteristics, and functioning.

Loss of the Right of Withdrawal in the Case of a Fully Performed Service

The right of withdrawal does not apply to service agreements (including SIM Card Activation and provision of an eSIM Card) for which the Consumer is required to pay a price, if the Seller has fully performed the service with the Consumer’s express prior consent and after informing the Consumer before performance begins that, once the service has been fully performed, the Consumer will lose the right of withdrawal. Consent is given in the Activation form by selecting a separate checkbox that is not pre-selected by default (see § 9 section 5 of these Terms and Conditions).
