This English version is provided for convenience. The official version of this document is in Russian. If the English and Russian versions differ, the Russian version shall prevail to the extent permitted by applicable law.

1. GENERAL PROVISIONS

This document sets out the terms governing the use of the kupiesim.ru website, placement and payment of orders, and delivery of digital eSIM profiles and associated prepaid mobile data packages.

The Seller is Individual Entrepreneur Sergey Vladimirovich Tokarev (ИП Токарев Сергей Владимирович), hereinafter referred to as Kupi eSIM or the Seller. An individual placing an order for personal, family, household, or other purposes unrelated to business activity is hereinafter referred to as the Customer.

An order may be placed after registration on the website or without registration as a guest. Before payment, the Customer must review these Terms, the specifications of the selected Plan, and the Privacy Policy.

This document constitutes an offer to enter into an agreement on the terms stated herein. The agreement is deemed concluded when successful payment of the order is confirmed. The terms of the specific Plan displayed on the Plan page and during checkout form part of the agreement.

The relationship between the Seller and the Customer is governed by the laws of the Russian Federation. Nothing in these Terms limits any mandatory consumer rights granted to the Customer by applicable law.

2. DESCRIPTION OF THE SERVICE

2.1. eSIM and Plan

An eSIM is a digital profile installed on a compatible device. Together with the eSIM, the Customer receives the selected prepaid mobile data package, hereinafter referred to as the Plan. Unless expressly stated otherwise on the Plan page, the eSIM provides mobile data only and does not include a telephone number, voice calls, or SMS.

The covered country or region, data allowance, validity period, available networks, start of the validity period, and other material specifications are stated on the page of the selected Plan. Actual network availability and service quality depend on the coverage and technical conditions of mobile network operators at the location of the Customer.

2.2. Placing an order

To fulfil the order, the Customer must provide a valid email address. An authenticated Customer can also access the eSIM in the My eSIMs section. The Customer is responsible for the accuracy of the email address and any other information provided.

The Seller may request only the additional information reasonably required to process payment, fulfil the order, provide technical support, or comply with applicable law.

2.3. Device compatibility

Before payment, the Customer must ensure that the device supports eSIM, is not locked by a mobile network operator, and permits eSIM installation for the selected country or region.

The list of compatible devices published on the website is provided for reference and may not include newly released models or specific regional device versions. If there is any doubt, the Customer should check the manufacturer documentation or contact customer support before payment.

2.4. Customer obligations

The Customer must follow the eSIM installation and configuration instructions, must not use the service for unlawful or fraudulent purposes, and must not take any action that could disrupt the website, payment system, or mobile operator networks.

If abuse or fraudulent activity is detected, the Seller may suspend service to the extent and in the manner permitted by applicable law and notify the Customer using the available contact details. Such suspension does not prevent the Customer from exercising any lawful rights relating to defects in the service.

3. INSTALLATION, ACTIVATION, AND VALIDITY

The Customer installs the eSIM using the provided QR code or quick installation link and configures the device in accordance with the instructions.

Unless stated otherwise on the Plan page, the Plan validity period begins when the eSIM first connects to a supported mobile network in the country or region covered by the Plan. Installing the eSIM before travel does not necessarily start the Plan validity period.

The eSIM must be initially activated within 39 calendar days from the purchase date. If the eSIM is not activated during this period by connecting to a supported mobile network in the country or region covered by the Plan, the eSIM and its assigned Plan expire and cannot subsequently be activated or used.

If the eSIM is activated within the 39-day period, its subsequent period of operation is determined by the validity period of the purchased Plan displayed during checkout.

The QR code and the ability to reinstall an eSIM may be restricted by the eSIM provider or device manufacturer. The Customer should contact customer support before deleting an eSIM from a device. Deleting an eSIM does not terminate obligations that arose before deletion.

The agreement relating to a specific Plan terminates when the data allowance is fully used or when the Plan validity period expires. Terms relating to claims, refunds, liability, and personal data continue to apply for the periods required by applicable law.

4. PRICE AND PAYMENT

The price is stated in Russian roubles on the Plan page and during checkout. The total amount payable is shown before payment. Taxes are applied in accordance with the tax regime applicable to the Seller. If VAT is required by law, it is included in the displayed price.

Available payment methods may include bank cards, the Faster Payments System, T-Pay, and MIR Pay. The payment form displays the methods available for a particular transaction. Payments are processed by CloudPayments. The Seller does not receive or store the full bank card number, expiry date, or security code.

An electronic receipt is sent to the email address or telephone number provided for the payment, in accordance with applicable law.

5. eSIM DELIVERY

After payment is confirmed, the Seller begins automatic eSIM provisioning. The QR code, ICCID, and installation information are displayed on the order result page and sent to the email address provided during the purchase. An authenticated Customer can also access this information in the My eSIMs section.

An eSIM is normally provisioned within a few minutes. If the eSIM is not delivered due to a technical failure, the Customer should contact customer support. The Seller must deliver the eSIM, provide an equivalent replacement with the consent of the Customer, or refund the payment in accordance with applicable law.

6. ORDER CANCELLATION AND REFUNDS

6.1. Unused eSIM

The Customer may request cancellation within 30 calendar days from the purchase date if neither the eSIM nor the Plan has been used, no mobile data has been consumed, and the eSIM provider technically permits cancellation of the Plan assignment. This period does not limit any longer claim period expressly provided by applicable law.

If the eSIM cannot be installed or used due to a confirmed technical defect attributable to the Seller or the eSIM provider, the Customer may request correction of the defect, an equivalent replacement, or a refund in the cases and manner provided by applicable law.

6.2. eSIM for which usage has started

Once mobile data usage begins, no refund is provided due to a change of plans, selection of the wrong country or Plan, the eSIM no longer being required, or an accidental purchase.

An exception may apply if internet access stops after usage has begun due to a confirmed technical issue attributable to the Seller, the eSIM provider, or a supported mobile network and is not restored within 48 hours after the support request is registered. The 48-hour period starts after the Customer provides the information reasonably required for diagnosis, provided that the device is within the stated coverage area and all required settings have been applied.

If the issue is not resolved within this period, the Customer may request an equivalent replacement or a refund, taking into account the nature of the defect and applicable law. The 48-hour period is provided for diagnosis and restoration of the service and does not restrict the rights of the Customer where applicable law permits an earlier claim.

6.3. Circumstances not treated as a technical defect attributable to the Seller

Lack of connectivity is not, by itself, grounds for a refund if it is caused by an incompatible or carrier-locked device, use outside the Plan coverage area, disabled data roaming, incorrect settings, lack of coverage from a particular operator at the location, or failure to follow the installation instructions. The Seller and the Customer must cooperate in good faith to diagnose and identify the cause of the issue.

6.4. Unauthorised and fraudulent transactions

Reports of unauthorised or fraudulent transactions are subject to review. The Seller may request information necessary to identify the order and prevent abuse. Such review does not restrict the right of the Customer to contact a bank, payment system, or government authority.

6.5. How to submit a request

To request a refund or replacement, the Customer must email support@kupiesim.ru or use the contact methods listed on the support page. The request should include the email address used for payment, purchase date, ICCID or order number, a description of the issue, and, where available, screenshots showing device settings and error messages.

The request will be reviewed within the period prescribed by applicable law. If a refund is approved, the Seller will initiate it using the original payment method. The time required for funds to be credited after initiation depends on the bank or payment system.

Costs of alternative connectivity, roaming, hotel internet, another SIM card or eSIM, and other indirect expenses are considered in accordance with applicable law where their amount and causal connection with a breach by the Seller are documented.

7. LIABILITY

The Seller is responsible for proper fulfilment of the order, accuracy of information provided by the Seller, and defects in the service to the extent required by applicable law.

Operation of an eSIM depends on the infrastructure of third-party mobile network operators. The Seller cannot guarantee identical speeds, uninterrupted coverage at every location within the stated territory, or the complete absence of short interruptions, but must assist with diagnosis and resolution of issues within its capabilities.

The parties are released from liability for failure to perform obligations due to force majeure to the extent that such circumstances directly prevent performance. This provision does not release the Seller from obligations that cannot be excluded by agreement.

8. PERSONAL DATA

Personal data is processed to place and fulfil orders, process payments, send the eSIM and electronic receipt, provide technical support, prevent fraud, and comply with legal obligations. Detailed terms of processing are set out in the Privacy Policy.

Where consent to personal data processing is required by law, such consent must be requested separately from acceptance of these Terms. Data required to fulfil an order may be disclosed to the payment service, eSIM provider, mobile network operators, and electronic message delivery services only to the extent necessary for the relevant purpose.

9. CHANGES TO THESE TERMS

The Seller may publish a new version of these Terms on the website. An order already paid for is governed by the version in effect at the time of payment unless a change is required by mandatory law or otherwise agreed with the Customer. A new version applies to orders paid for after its publication date.
