Num API Terms
Version 2026-10-04.
These terms apply to every business that creates an account to use the Num API or the Num business console. By creating an account you agree to them on behalf of your company. They are written to be read; if anything is unclear, ask us before you rely on it.
"Num", "we" and "us" mean WorkersLab LLC, 30 N Gould St Ste R, Sheridan, WY 82801-6317, United States. "You" means the company whose account it is.
1. What you get
An account with a sandbox environment for building and testing, and, once we switch it on for you, a live environment in which orders issue real travel eSIMs.
Sandbox is not real. Sandbox eSIMs are demonstration data. They do not connect to any network and must not be given, sold or shown to a customer as a working eSIM. Sandbox credit has no monetary value.
2. Your account
- You are responsible for everything done with your account and your API keys. Keep keys secret and on your own servers. Tell us at once if a key may have leaked; we will revoke it.
- The information you give us about your company must be true, and you must keep your contact address current.
- Live access is granted at our discretion. We may ask what you intend to sell and to whom before granting it, and we may decline.
3. Prices and payment
- All prices, charges and balances are in United States dollars.
- The price of an order is the wholesale price shown for that plan when the order is placed. Prices can change at any time; the catalogue is the current price.
- Live credit is prepaid. We issue an invoice; when it is paid we add that amount to your balance. Orders draw on the balance. We do not issue eSIMs on credit you have not paid for.
- You set the price you charge your own customers, and you are responsible for any taxes on your sales.
4. No refunds; cancellation
- Credit is non-refundable. Prepaid credit that you have not spent is not returned, including when an account is closed.
- An issued eSIM is not refunded, whether or not it is installed or used.
- You may cancel an eSIM at any time through the API or the console. A cancelled eSIM stops working and cannot be restored. Cancelling does not return credit.
- If we are unable to issue an eSIM you ordered, the charge for that order is reversed to your balance. That is the only circumstance in which a charge is reversed.
5. Our right to cancel or suspend
We may cancel or suspend any eSIM, any order, any API key or your account, at any time and without notice, including where we believe there is fraud, misuse, a breach of these terms, a risk to a network or to other customers, an unpaid invoice, or a legal or regulatory reason to do so. Where we reasonably can, we will tell you what we have done and why. A cancellation under this section does not entitle you to a refund or a credit.
6. What you may not do
- Resell access to the API itself, or let another company use your keys.
- Use eSIMs for unlawful purposes, for automated or machine-to-machine traffic not agreed with us, or in a way that breaches a network's fair-use rules.
- Attempt to discover, contact or deal directly with our suppliers, or to work out our costs. The identity of our suppliers and the prices we pay are confidential.
- Probe, overload or attempt to circumvent the API's limits or security.
- Describe yourself as Num, or imply that we endorse your product, without our written agreement.
7. Your customers
You are the seller to your customers. You are responsible for telling them what they are buying, for their support in the first instance, and for complying with the consumer, telecommunications and data-protection law that applies to you. Give us only the personal data we need to provide the service; an order requires none.
8. Service
We aim for the API to be available at all times and for eSIMs to be issued within seconds, but we do not guarantee either. Mobile networks are operated by third parties: coverage, speed and availability vary by place and time and are outside our control. Plans and destinations may be withdrawn.
9. Liability
To the extent the law allows, the service is provided as is. We are not liable for indirect or consequential loss, lost profit, or loss arising from a network being unavailable. Our total liability to you in any twelve-month period is limited to the amount you paid us for orders in that period.
10. Changes and ending
We may change these terms. When a change is material we will tell the contact on your account, and continuing to use the API after that is acceptance of the new terms. You may stop using the API at any time. Sections 3, 4, 6, 7 and 9 continue to apply afterwards.
11. Law
These terms are governed by the laws of the State of Wyoming, United States, and its courts have jurisdiction, unless a law that applies to you cannot be excluded by agreement.
