1. The Company Behind the Service

Seyferttec LLC is a technology company legally based in the United States (Delaware). We operate solutions focused on connectivity, software, and operational support for end users, travel agencies, content creators, and business teams.

We provide support in both English and Spanish, with real human assistance — not just automated articles.

2. What is Seyferttec eSIM

Seyferttec eSIM is a digital international mobile data service (eSIM). You buy online, receive a QR code, and activate your plan on your compatible phone — usually within minutes.

This saves you from buying local SIMs at airports or depending on insecure, limited public Wi-Fi.

Our affiliate program allows agencies, tour operators, content creators, and hospitality businesses to earn commissions for every activation they generate.

4. Transparency & Support

Before payment, we show compatibility, coverage, price, and duration. After payment, you receive your QR code and installation instructions. If anything goes wrong, we’ll resolve it with you in real time.

If we were unable to provide service (for example, if the eSIM never worked and no data was used), we apply refund or store credit rules according to our Refund Policy.

Our goal is simple: to help you travel connected and stress-free.
