Terms of service

Sīrū BV is registered in the Netherlands (KvK 60129336). When we say “we” or “us” in this document, we mean Sīrū BV. When we say “you”, we mean the person or legal entity buying a data plan from us.

We sell prepaid data plans delivered as eSIMs for mobile devices. Each plan is tied to a destination (country or region), a data amount, and a validity period. When you buy a plan you get a QR code and an installation link by email.

Your plan starts counting down from the moment your phone first connects to one of the carriers we partner with in the destination. Until then, the plan is considered installed but not activated.

All Sīrū eSIM plans are 100% digital goods. We do not ship physical SIM cards, plastic trays, or paper mail.

Delivery Method: Immediately upon successful payment, your eSIM QR code, installation details, and setup instructions are sent to your provided email address and displayed directly on your confirmation screen.

Delivery Fee: Free (€0.00). There are zero shipping, handling, or international customs charges worldwide.

Delivery Timeframe: Instant (typically within 10 to 60 seconds, up to 5 minutes). If you have not received your email, check your spam/junk folder or access your plan anytime in My eSIMs.

• Not to use the service in ways that violate the law where you are physically located or where Sīrū is registered.
• Not to resell access without a commercial agreement with us.
• Fair-use caps apply to “unlimited” plans. Caps are visible at the point of sale; we won’t change them mid-plan.

eSIM plans are delivered digitally. No physical item needs to be returned, and we do not charge return postage or a refund handling fee.

180-day free refunds for unused, unactivated eSIMs. You may request a full refund within 180 days of digital delivery for an unused eSIM plan that has never been activated, including if you change your mind or your travel plans change. The plan must have no data usage and must not have been activated. There is no return, cancellation, handling or restocking fee. This policy applies in all buyer countries we serve.

Activation failures and technical issues. We offer a full refund within 30 days of purchase if the plan fails to activate for reasons within our control. We offer a partial refund if more than half of the plan’s data allowance or validity period remains and a technical issue prevents use.

Refunds are issued within 5 working days. We use the original payment method whenever possible. If your payment provider can no longer refund the original payment method, we will agree an alternative way to return your money at no cost to you. You will receive the full refund amount due, with no refund or transfer fees deducted. We don’t offer “store credit” unless you ask for it.

To request a refund, email support@siru.world with your order number and cancellation request. For an activation failure or technical issue, include a description of the issue; we may ask for device or settings details to help investigate.

These voluntary refund terms do not limit any rights you have under applicable consumer law.

The shortest summary we can offer: we collect the minimum needed to deliver your plan and run the business, we don’t sell your data, and you can export or delete everything we have about you. Full details in the Privacy policy — one click away.
