Terms & Conditions

1. Eligibility and your account

You must be at least 18 years old, or the age of majority where you live, to use the Service. You sign in with an email code, Apple or Google. Keep access to that email or account secure: you are responsible for activity on your account. Each account has one SAIMING eSIM.

2. The Service

SAIMING sells mobile data for travel, delivered on an eSIM. The eSIM provides data only: it has no phone number and cannot make regular calls or send SMS. Your existing SIM keeps your number. The eSIM cannot be used for emergency calls; use your primary SIM or a local landline. Data is carried by our partner networks; coverage, network type (4G/5G) and speed depend on the local network, your location and your device, and are not guaranteed. The eSIM works only in the countries and regions listed in the app. To use the eSIM you must set it as your mobile data line and turn on data roaming for it, as shown in the app. To avoid charges from your home carrier, turn off data roaming on your primary SIM or set it not to use mobile data.

3. Device compatibility

You need an eSIM-capable device that is not locked to another carrier. The app shows whether your device appears to support eSIM, but you are responsible for confirming compatibility and unlock status before you buy. An eSIM profile can usually be installed on only one device, and deleting it from your device may make it unusable.

4. Plans and balance

• Data plans give a fixed amount of data for use in the country or region named in the plan, for the validity period shown in the app. When the data is used up or the validity period ends, the plan stops.
• When a plan starts: if your eSIM is not yet installed and activated when you buy, the plan starts once it is; if it is still not activated 30 days after purchase, the plan starts automatically on day 30. If your eSIM is already activated, the plan starts right after payment. A plan renewed by auto-renew starts when the previous plan's validity period ends, even if its data ran out earlier.
• SAIMING balance (pay as you go) is prepaid credit held in US dollars and used for data at the per-country rate shown in the app when the usage is recorded, which is usually within a few hours of use. Rates may change; a change applies to usage recorded after it takes effect. Your balance expires 3 years after your most recent top-up; each top-up, or credit we add, extends the whole balance.
• Unused data and expired balance are not refunded or carried over, and plans and balance have no cash value, except as set out in sections 7 and 11 or where the law requires. Plans and balance cannot be transferred, resold or exchanged for cash.
• Remaining-data and usage figures in the app are estimates and may lag behind actual use; the network operator's records prevail.

5. Prices and payment

Prices are shown in the app in US dollars before you pay and include applicable taxes and any fees shown at checkout. Payments are processed by Stripe; you can pay by card, Apple Pay or Google Pay. Your bank may charge foreign-exchange or other fees. We may change prices at any time; a change does not affect plans already bought, and balance is charged as set out in section 4. If a price is clearly wrong because of an obvious error, we may cancel the order and refund it in full. For some plans we authorise your card at purchase and capture the payment when the plan is provisioned; if we cannot provision it, we release the authorisation.

6. Auto-renew and auto top-up

If you turn on auto-renew for a plan, you authorise us to charge your saved card for the next plan shortly before the current plan's validity period ends, at the price shown when you turned auto-renew on, until you turn it off. If that price changes or the plan is withdrawn, auto-renew stops and we tell you; we never charge a new price without your new consent. If you turn on auto top-up, you authorise us to charge your saved card the top-up amount you chose, plus any service fee shown when you turn it on, whenever your balance falls below US$5. Auto top-up is based on recorded usage, which can lag behind actual use, so your data may stop before a top-up is made. If repeated charges fail, we turn auto top-up off and tell you. When you turn on either, we email you a confirmation of the amount, when you will be charged and how to turn it off. You can turn either off at any time in the app; this stops future charges but does not refund charges already made (see section 7 for refunds).

7. Cancellations and refunds

• Plans before they start: you can cancel any data plan for a full refund until it starts (see section 4 for when a plan starts). This includes a plan paid by auto-renew, until it starts.
• Device not supported: if your device turns out not to support eSIM, or is carrier-locked and cannot be unlocked, we refund unused plans and top-ups on proof (for example a screenshot of the lock status), as long as no data has been used.
• Plans that will not connect: if a started plan does not work in its coverage area because of a fault on our side or our network partners', email us within 7 days of the plan starting and while it is still valid. If we cannot fix it within a reasonable time after your report, we refund the plan in full if no data was used, or in proportion to the unused data otherwise.
• SAIMING balance: top-ups, including those made by auto top-up, cannot be refunded once they have been added to your SAIMING balance, except as set out in this section or where the law requires. If a top-up cannot be added to your balance, for example because of a technical failure, we refund it in full.
• Not refundable: data already used; plans that have started, except as above; expired plans and balance; and problems caused by device settings (for example data roaming turned off or the wrong data line selected), by deleting the eSIM or moving it to another device, or by use outside the plan's coverage area. Slower speeds or a different network type caused by local network conditions are not a fault.
• Refunded without you asking: duplicate charges, and orders we cannot fulfil (for example when eSIMs are out of stock or provisioning fails). If we only authorised your card and did not capture the payment, we release the authorisation instead.
• How to ask: email cs@saiming.com from the address on your account, with your order number. We aim to reply within a few business days. Refunds go back to the original payment method; your bank may take 5–10 business days to show them.
• Chargebacks: please contact us before disputing a charge with your bank. While a dispute is open, we may suspend the plan or balance it paid for.
• Withdrawal rights: if the law where you live gives you a right to withdraw from a purchase without giving a reason (for example, 14 days in the EEA and UK), the following applies. By buying a plan, you ask us to start it during that period as described in section 4, and you lose the right to withdraw once it has started; until then you can cancel for a full refund as above. A top-up is added to your balance as soon as you pay; by topping up you ask us to do this immediately and you lose the right to withdraw from it. To withdraw, email cs@saiming.com with your order number.
• Nothing in these Terms limits refund or other rights you have under mandatory consumer law where you live.

8. Coupons and referrals

Where available, coupons and referral rewards are subject to the conditions shown with them, including validity dates, eligible products and the limit of one coupon per order. Refunds of a discounted purchase cover only the amount you actually paid. We may cancel rewards obtained by fraud, multiple accounts or other abuse.

9. Acceptable use

You agree not to: resell or commercially redistribute the Service; use it in SIM boxes, gateways or other equipment that relays traffic; use it for unlawful activity, fraud or network abuse; interfere with or reverse-engineer the Service; or create accounts with false information. Some countries require foreign devices or SIMs to be registered, or limit how long they can be used on local networks; you are responsible for complying with those rules, and interruptions caused by them are not a fault. We may suspend service that harms our networks or partners or breaches these Terms.

10. Service changes and availability

We may add, change or withdraw countries, plans and features. The Service depends on third-party networks and may be interrupted by maintenance, network failures, or events beyond our control. We are not responsible for charges from your home carrier, including roaming on your primary SIM.

11. Ending the Service

You can delete your account in the app at any time, from your account settings. Deleting your account deactivates your eSIM and ends active plans; plans that have not started and renewals already paid are cancelled or refunded, but remaining SAIMING balance is not refunded, except where the law requires; the app shows your balance before you confirm. Deleting your account does not cancel refunds you are already owed; we complete them to your original payment method. If you have not used your account for 12 months (no sign-in, app use or purchase) and it has no SAIMING balance and no plan that is active or yet to start, we may close it after emailing you at least 30 days in advance. We may also suspend or close your account if you breach these Terms or if required by law or our partners; where we close it without your breach, we will refund unused prepaid amounts.

12. Intellectual property

We grant you a personal, non-exclusive, non-transferable, revocable licence to use the app for your own non-commercial use: if you got it from the Apple App Store, on Apple-branded products you own or control, as permitted by the Usage Rules in the App Store Terms of Service; otherwise, on devices you own or control. All rights in the app and the SAIMING name and logo remain ours or our licensors'.

13. Disclaimers

To the extent permitted by law, the Service is provided "as is" and "as available". We do not promise that it will be uninterrupted, error-free, or available in every location.

14. Limitation of liability

To the extent permitted by law, we are not liable for indirect, incidental or consequential losses, or for loss of profits, data or business opportunity. Our total liability for any claim relating to the Service is limited to the greater of the amount you paid us in the 6 months before the claim arose and US$100. Nothing limits liability for death or personal injury caused by negligence, fraud, or anything else that cannot be limited by law.

15. Governing law and disputes

These Terms are governed by the laws of the State of Wyoming, USA, and applicable US federal law, without regard to conflict-of-law rules. Please contact us first so we can try to resolve any issue. If we cannot, disputes will be heard by the state or federal courts located in Wyoming, but if you are a consumer you may also bring proceedings in the courts where you live and keep the protection of its mandatory laws.

16. Changes to these Terms

We may update these Terms. We will post the new version here and, for material changes, notify you in the app or by email at least 14 days before they take effect. If you do not agree, you can stop using the Service and delete your account before then.

17. Apple App Store

If you downloaded the app from the Apple App Store: these Terms are between you and us, not Apple, and we, not Apple, are solely responsible for the app and its content. Apple has no obligation to provide maintenance or support for the app. We are solely responsible for providing maintenance and support for the app, for any product warranties to the extent not effectively disclaimed, for addressing any claims relating to the app, and for investigating, defending, settling and discharging any claim that the app infringes third-party intellectual property rights. If the app fails to conform to any applicable warranty, you may notify Apple, which will refund the app's purchase price (if any); to the maximum extent permitted by law, Apple has no other warranty obligation. Apple is not responsible for addressing any claims relating to the app, including product liability claims, claims that the app fails to conform to any applicable legal or regulatory requirement, and claims under consumer protection, privacy or similar legislation, nor for investigating, defending or settling any claim that the app infringes third-party intellectual property rights. You must comply with applicable third-party terms when using the app. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

18. General

These Terms and our Privacy Policy are the entire agreement between you and us about the Service. If any part of these Terms is found unenforceable, the rest stays in effect. If we do not enforce a right, we have not waived it.

You may not transfer your rights under these Terms without our consent. We may transfer ours to a company that takes over the Service; your rights under these Terms are not affected.

We are not responsible for failures caused by events beyond our reasonable control, such as network outages, natural disasters or government action. This does not affect your right to a refund under section 7.

These Terms are written in English. If we provide a translation and it conflicts with the English version, the English version prevails, unless your local law requires otherwise.
