Terms of Service

Last updated: October 20, 2026

These terms are an agreement between you and RagHubs Inc. ("lumsim", "we", "us"), 8 The Green, Ste R, Dover, DE 19901, USA. They apply when you use this website and when you buy an eSIM or a data add-on from us. By placing an order, you accept them.

Please read them together with our Refund Policy and Privacy Policy.

lumsim sells prepaid mobile data plans delivered as eSIMs, and data add-ons for eSIMs you bought from us. The data service runs on partner mobile networks in the destinations listed for each plan.

Plans are for mobile data only. Unless the plan page says otherwise, they don't include a phone number, calls or text messages, and they can't be used to call emergency services. Keep another way to reach emergency services while you travel.

  • You must be at least 18 years old, or the age of majority where you live if that is higher.
  • You need a phone that supports eSIM and isn't locked to a carrier. Please check before you buy, for example with our compatibility checker.
  • The country of residence you give at checkout must be true. We use it to work out tax and to check whether we can sell to you.
  • We don't currently sell to residents of the European Union (including its territories such as Åland and the French overseas regions), the other countries of the European Economic Area (Norway, Iceland and Liechtenstein), the United Kingdom, Switzerland, Monaco or the Isle of Man. We never sell to countries under comprehensive US sanctions, and we may be unable to sell in some other countries. Checkout tells you whether we can sell to you. If the billing or card country of your payment turns out to be one where we can't sell, we cancel the order and refund you in full automatically.
  • Prices are shown in your local currency where we can. A price you see is held for up to 30 minutes. If it expires or changes, we show you the new price before you pay.
  • Tax depends on your country of residence, which you confirm at checkout. As tax law requires, we also check your billing country, card country and IP address.
  • In the United States and Canada, tax is added at payment. Everywhere else, the price shown includes any tax that applies.
  • You pay in full when you order. Your bank may charge its own fees, for example for a payment in a foreign currency.
  • Payments are processed by Stripe, which also issues your invoice and any credit note. An issued invoice is never changed; corrections are made with a credit note.
  • If you need an invoice for a company, choose this at checkout. To change invoice details later, contact us at support@lumsim.com.
  • Price changes never affect an order you have already paid for.

We deliver your eSIM right after payment, on your order page and by email.

  • Some orders are held for a security check, usually for up to 12 hours. If we don't approve the order, you get a full refund.
  • If we can't deliver your eSIM or add a data add-on you paid for, we refund you in full automatically.
  • To prevent fraud, new customers can buy a limited number of eSIMs, up to a limited amount, in their first 24 hours.
  • If we cancel an order for a reason that isn't your fault, we refund you in full.

An eSIM is digital and is delivered immediately. Where the law gives you a right to withdraw from an online purchase, at checkout you expressly ask us to deliver right away and acknowledge that you lose that right once the eSIM or data add-on is delivered. We confirm this in the email that delivers your order.

Separately from that, our Refund Policy gives you a full refund for an eSIM you have never installed, until its install-by date. Your other legal rights, for example if the service is faulty, are not affected.

  • Install your eSIM by the install-by date shown on your order page and in your email.
  • Depending on the plan, the validity period starts when the eSIM first connects to a network in a destination, or as soon as you install it. The plan page and your order page say which.
  • Data you don't use by the end of the validity period expires.
  • An eSIM can be installed on one device. If you delete it from your phone, it usually can't be installed again.
  • Keep your QR code and activation code private. Anyone who has them can install your eSIM.
  • Coverage and speed depend on the local partner networks. We can't guarantee coverage in every place or a particular speed.
  • Data add-ons are added to an eSIM you already have, under the conditions shown when you buy them.

You agree not to use lumsim or any eSIM for anything unlawful, not to resell eSIMs bought from us, not to buy with a payment method you're not allowed to use, and not to interfere with our website or the networks. If you break these rules, we may cancel the order or suspend the eSIM. Where the law allows, we tell you why.

If your eSIM doesn't work, contact us at support@lumsim.com. We review network problems case by case. If the service wasn't provided as described and we can't fix it, we refund you in full or in part. Refunds always go back to your payment method; we don't give store credit or a balance.

Please contact us before you dispute a payment with your bank. If you open a dispute, we suspend the eSIM while it is open and send Stripe and the card network the order records as evidence: your email address, IP address, when you accepted immediate delivery, when we delivered the eSIM and its email, and the eSIM's install and usage records. If the dispute is decided in our favour, we lift the suspension; if it is decided against us, the eSIM stays suspended.

If your card issuer warns us that a payment may be fraudulent, we cancel the eSIM if it has never been installed and refund it in full, together with its data add-ons. If it is already installed, we may suspend it while we look into the order.

You don't need an account to buy. To see your eSIMs in My eSIMs, you sign in with a code we email you. You can delete your account in My eSIMs once any unfinished orders are complete.

Nothing in these terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud, or for anything else the law doesn't allow us to exclude or limit. Nothing in these terms limits your rights under consumer laws that can't be excluded.

Subject to that, and as far as the law allows:

  • we aren't liable for loss that wasn't reasonably foreseeable when you placed the order, or for problems caused by events beyond our reasonable control, such as a network outage (this doesn't affect your right to a refund under "Problems and payment disputes");
  • if you buy for a business, we aren't liable for lost profit, revenue, business or data;
  • our total liability for an order is limited to the amount you paid for it.

We may update these terms. The version shown when you placed an order applies to that order. Changes apply only to orders placed after they are published.

These terms are governed by the laws of the State of Delaware, USA. If you are a consumer, this doesn't take away the protection of the mandatory laws of the country where you live.

If we have a dispute, please contact us first at support@lumsim.com so we can try to solve it. If we can't, claims may be brought in the courts of the State of Delaware. If you are a consumer, you may instead bring a claim in the courts, or before a consumer dispute body, where you live, and we bring claims against you only there, wherever the law gives you that right.

These terms don't require you to go to arbitration and don't take away your right to join a class action.

  • If a court finds part of these terms invalid, the rest stays in force.
  • If we don't enforce a right straight away, we can still enforce it later.
  • We may transfer this agreement to another company, as long as this doesn't reduce your rights.

These terms are written in English. Translations are provided for convenience. If a translation conflicts with the English version, the English version prevails, unless the law where you live requires otherwise.
