Terms of Service

LarkSim is an independent seller and Chinese-language guide provider. It sells physical SIM cards (Self-Setup and Full-Service) sourced from UK mobile operator giffgaff (giffgaff Limited), together with related vouchers, and provides the domestic dispatch, guidance, and after-sales assistance expressly included in the order. LarkSim is not an official site, agent, or affiliate of giffgaff, Virgin Media O2, Telefónica, or any target verification platform. The number, mobile service, account review, plans, top-ups, roaming, and suspension or restoration are controlled by giffgaff or its partners.

• You must register and place orders using a valid email address; your orders are linked to your account email
• Please provide your real name, a valid mobile number, and a complete delivery address
• You may place multiple orders from the same email address; each order is independent
• Please keep your login credentials secure; all orders placed under your account are deemed to be your own actions
• Do not use false details or shared payment instruments, and do not use products for bulk registration, spam, restriction evasion, account resale, or any other unlawful or abnormal purpose

For details on how we collect, use, and protect your personal information, please see our Privacy Policy.

• We currently support Alipay and WeChat Pay, both processed by Stripe (acquiring account located in Hong Kong SAR, China)
• Products are priced and charged in CNY (Chinese Yuan); the order page may display a reference price in USD or another currency alongside the corresponding CNY amount. The amount actually deducted from your account is the CNY amount as finally confirmed on the payment page
• After an order is created, it shows a 'pending payment' status until payment is completed; orders unpaid for 30 minutes will be automatically cancelled

• Upon successful payment we will dispatch your order within 24 hours via ZTO Express (public holidays excluded)
• Parcel tracking is synchronised to the order page via the KuaiDiNiao API
• Any loss arising from an incorrect address or phone number provided by you is your own responsibility

• The SIM supplied must conform to the order and be in a condition suitable for normal activation. Activation steps are detailed in the Activation Guide and FAQ
• Once activated, the number is bound to your giffgaff account. You are responsible for maintaining the account details, password, payment method, and subsequent use. Roaming, verification-code delivery, and continued availability depend on the operator, network conditions, and the target platform's current rules
• You must follow applicable law, giffgaff's official terms, and each target platform's rules. giffgaff may restrict, suspend, or terminate an account or SIM because of security checks, unusual use, payment disputes, inaccurate details, or suspected rule violations

For detailed refund and after-sales terms, please refer to our Refund Policy.

A physical SIM contains unique activation information. Activation, number binding, or trial use creates irreversible account or usage records and substantially reduces resale value. Because of this product characteristic, we give a prominent notice on the product and mandatory checkout path and require your affirmative confirmation that physical SIM cards are not eligible for a seven-day no-reason return. A voucher is a digital product with a unique code and enters code allocation and digital fulfilment as soon as payment succeeds. Except where we ultimately cannot fulfil the order, a duplicate charge occurs, the code was already invalid or used at delivery, the amount or product does not match, or applicable law requires a remedy, a voucher order cannot be cancelled, returned without reason, exchanged for cash, or refunded, even if the code has not been viewed, claimed, or redeemed. Code issues are primarily remedied by re-delivery or replacement with a valid equivalent code. This paragraph does not restrict statutory product-quality or fulfilment rights.

For the important operator-suspension, roaming, verification, and third-party compatibility risks, also read and separately acknowledge the Risk Disclosure and Disclaimer.

• An account restriction, SIM suspension, or failure on one verification platform does not by itself prove a defect in the physical SIM. The cause must be assessed using device recognition, ordinary communications, giffgaff status, and official responses
• To the extent permitted by law, we are not responsible for indirect loss, loss of business opportunity, third-party subscription loss, or data loss caused by the customer's unlawful or abnormal use, device or network conditions, third-party platform action, or unforeseeable operator-policy changes
• These limitations do not apply to loss caused by our intent or gross negligence, personal injury, or statutory claims involving product quality, misleading statements, fraud, or other non-excludable rights

We may update these Terms. Later versions generally apply only to new orders placed after their effective date and will not, by publication alone, retrospectively reduce rights or exclude existing liability. Legally required changes will be prominently notified. These Terms are governed by the laws of the People's Republic of China. Nothing here restricts a consumer's lawful right to complain, seek mediation or arbitration, or bring proceedings before a court of competent jurisdiction.
