Terms of Service

LarkSim sells physical SIM cards (Self-Setup and Full-Service) sourced from UK mobile operator giffgaff (giffgaff Limited), and provides domestic express delivery, activation guidance, usage consultation, and after-sales support to help you stay connected — for calls, SMS, and data — during overseas travel or study abroad. The giffgaff number service itself is provided directly to end users by giffgaff Limited; account operations, top-up, number validity, and related matters are governed by giffgaff's official policies and are completed by the end user through giffgaff's official channels.

• 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

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 SF Express or China Post (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

• SIM cards are compliant products that can be activated and used normally. Activation steps are detailed in the Activation Guide and FAQ
• Once a SIM card is activated, the number is bound to your giffgaff account; you are responsible for the use and maintenance of that account. During your time abroad you may use the SIM for data, calls, and SMS in the normal way
• Please use your SIM card in compliance with applicable domestic and international laws and regulations. Use for fraud, money laundering, or other illegal purposes is strictly prohibited. You bear all consequences arising from any unlawful use

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

Regarding the seven-day unconditional return right under Article 25 of the Consumer Rights Protection Law: SIM cards are number-bound products that cannot be resold once activated. Accordingly, the seven-day unconditional return right does not apply to SIM cards that have been opened and activated. The specific refund rules and exceptions are governed by the Refund Policy; please confirm you have read and understood these before placing your order.

• For impacts arising from changes to giffgaff's official policies, overseas network operator outages, logistics force majeure, or similar events, we will make reasonable efforts to assist but we do not accept liability for indirect losses
• Our total liability under these Terms is limited to the actual amount paid for the relevant single order

We may update these Terms from time to time; material changes will be published on this page with the updated date noted. These Terms are governed by the laws of the People's Republic of China, and any disputes will be submitted to the court of competent jurisdiction as required by law.
