Terms of Service

Last updated: 16 September 2026

1. Operator and scope

This website is operated by SmartSim Technology Limited, using the SmartSimPro name. “We”, “us” and “our” refer to SmartSim Technology Limited.

Company address: Rm 5, 10/F, CARNIVAL COML BLDG, 18 JAVA RD, North Point, Hong Kong.

Contact: service@smartsimpro.com, +86 181 2451 2054.

These terms cover use of this website and orders placed through it. Product descriptions, plan conditions, the Shipping Policy and the Return & Refund Policy provide additional information relevant to a purchase. Our Privacy Policy explains how we handle information.

2. Eligibility and account use

You must be legally able to enter into the relevant purchase or act with valid authority for the person or business making it. Please provide accurate contact, delivery and order information and promptly correct information that affects an order.

If you use a customer account, keep your access details secure and contact us if you believe the account has been used without authorisation. You must not use the website unlawfully, interfere with its operation, attempt unauthorised access or misuse another person's information.

3. Products, plans and compatibility

We offer physical SIM cards, eSIM plans and connectivity devices. Features vary by product and destination. Before ordering, check the product's supported destinations and networks, device compatibility, data allowance, validity period, activation conditions and any fair-use or speed restrictions shown in the offer.

A device may need to be network-unlocked, support the relevant frequency bands or eSIM technology, and use the required settings. Products described as data-only do not include voice calls or SMS unless the offer expressly says otherwise.

Connectivity depends on factors such as the supported network, coverage, device, location and network conditions. We do not promise that every product works with every device, or that service will be uninterrupted at every location. These statements do not limit your rights where a product is defective or does not match its description.

4. Prices, payment and orders

Review the product, quantity, currency, delivery information and total shown at checkout before paying. Available payment methods are those offered for the particular checkout. Your payment provider may apply its own currency conversion or fees.

An acknowledgement that an order has been received is not, by itself, a guarantee that a product has shipped or a service has been activated. We may need to check payment, availability or information necessary to fulfil the order. If we cannot fulfil an order, or identify a material pricing or listing error, we will contact you about the available resolution and any refund due. We will not require you to pay a different price without your agreement.

5. Delivery, activation and top-ups

Delivery information for physical products is set out in our Shipping Policy. Digital delivery and activation instructions, where relevant, are described in the product offer or order communications.

Follow the instructions for the product purchased. The event that starts a plan's validity period may differ between products; check the stated activation conditions before inserting, installing or activating a SIM or eSIM. Contact us if those conditions are unclear.

Top-up options depend on the product. Use the top-up route specified for your SIM or plan and check any separate conditions before purchasing. A purchase does not authorise recurring charges unless a recurring arrangement is clearly presented and separately accepted.

6. Cancellations, returns and faulty products

Please review our Return & Refund Policy and the product-specific conditions provided before purchase. Contact us before posting a return or attempting a cancellation.

If a product arrives damaged, is faulty or does not match the description, contact us with the order details and a description of the problem. We will assess the issue and the remedy available under the purchase terms and applicable law. A change-of-mind return restriction does not remove mandatory rights relating to defective or misdescribed goods or services.

7. Website content and external services

Website content, branding and materials are protected by applicable intellectual property rights. You may use the website for legitimate product research, purchases and related support. You must not falsely imply a partnership with us or misuse our materials or systems.

The site uses Shopify and may link to payment, referral, top-up or other external services. Separate terms may apply when you use those services. Please review the information shown by the relevant provider.

8. Availability, changes and responsibility

We may maintain or update the website and correct errors. Changes to future offers do not by themselves change the conditions already agreed for an existing purchase. We may restrict access where reasonably necessary to address unlawful activity, misuse or a security risk.

Nothing in these terms excludes or limits a right or liability that cannot lawfully be excluded or limited, including mandatory consumer rights. Any limitations concerning network availability or external services are subject to those rights. These terms do not require you to waive protections that apply to you under mandatory law.

9. Questions and disputes

Please contact service@smartsimpro.com if you have a complaint or a question about an order or these terms. Include your order reference and the outcome you are requesting so we can investigate.

These terms do not prevent you from using a court, regulator or dispute-resolution process available to you under applicable law. If a provision is unenforceable, that does not automatically invalidate the remaining provisions.

10. Updates

We may update these website terms. Material changes will be communicated where required, and changes will not retrospectively remove rights arising from an existing purchase. Please retain the product information and terms applicable when you order.
